• How to unit test with lots of IO

  - by Eric

  I write Linux embedded software which closely integrates with hardware. My modules are such as : -CMOS video input with kernel driver (v4l2) -Hardware h264/mpeg4 encoders (texas instuments) -Audio Capture/Playback (alsa) -Network IO I'd like to have automated testing for those functionalities, such as integration testing. I am not sure how I can automate this process since most of the top level functionalities I face are IO bound. Sure, it is easy to test functions individually, but whole process checking means depending on tons of external dependencies only available at runtime.

• Implications of Cisco open-sourcing H.264? [on hold]

  - by Suman

  Cisco has announced that it will license and open-source the H.264 video codec. As a result of this, Firefox will be embedding H.264 playback functionality in future versions of Firefox. What implications, if any, will this have for programmers building software and/or hardware dealing with video (and WebRTC in particular)? (And if programmers.SE isn't the right forum, please feel free to suggest a better option.)

• How do I rip a dvd including menus and extras to a menu driven divx file (or any lossy format that supports menus)?

  - by John Baber

  I am asking exactly this question for the same reason, but would like to archive dvds as small, low quality video, while preserving the menu choosing experience. I would like to rip my dvds to something that has the same menus but whose video is in a much more compressed format. I do not want to copy a dvd to an .iso image. How can this be done in the most automatic (hopefully CLI) way possible? Any format is fine so long as playback on linux is possible.

• No sound on Dell Inspiron 6400n

  - by yanski

  After a clean install of Ubuntu 12.04 on my Dell Inspiron 6400n Laptop there is no sound on any application I use apart from the log in screen ready noise. If I click on the speaker icon on the top panel then sound settings it tells me that the default playback device is S/PDIF. In alsamixer the slider is set to zero. I am sure it should be HDA intel or similar. How can I get the sound working please...?

• What is causing random hard freezes on my system? Kaspersky?

  - by Christian Ivicevic

  The last few weeks I experienced a new strange behavior of my computer. Sometimes Windows 7 just freezes with no real reason at all. While listening to music for example the playback hangs and you can hear a very nasty sound. Neither mouse nor keyboard input is handled and everything is just stuck. Using Ubuntu this does not happen, so I think it is just a matter of driver issues or a Windows 7 bug. Furthermore I am really suspicious about Kaspersky (Internet Security 11) and so I let it perform a complete virus scan while no other app is running. At about 50% it happened again and I needed to restart the computer by holding the power button the bad way... A really weird thing is that playing Skyrim this happened once, however music playback did not stop. Only the framerate dropped to 0 and sometimes for a few seconds I am able to move. Therefore I am really confused as furthermore no bluescreen pops up. Memtest told me that everything seems to be alright... Can anyone explain me which data you need about my hardware and software (and which tools tools to use to gather the informatik) to be able to provide any help on my problem?

• Htpc aka "Media Center": cheap and *silent*?

  - by Unknown

  It may be me, or the place I live (Italy), but it seems pretty hard to get a build or a prebuilt nettop or a laptop that fits the need. I need something silent able to playback all h.264 fullhd content without stuttering, and well (and not loosing the hw acceleration because of softsubs...) silent not ugly silent and (possibly) cheap. I'm going the linux route, therefore i'm moving towards a cpu-based or nvida-integrated solution (i don't think ati hw accelerated playback - or the intel "hd" acceleration - is useable yet). Ion nettop; it's either the Acer Revo (but here it's incredibly pricey and it's hard to find the dualcore version) or the Asrock Ion 330, that in the current version is rated "silent" at 26Db. 26. Sounds pretty noisy to me!!! the previous version was even worse. was this product really aimed at htpc market?? the Dell Zino - i think it's ATI based unfortunately. Laptop: correct me if I'm wrong: sub 600€/$ units are quite loud under full load (because of the tiny fans). ULW laptops are indeed quite similar: tiniest fans = high pitched noise and the cpu still lacks power for non hd-accelerated video decoding Handmade build: little money can be saved with underpowered cpus, a low-midrange cpu would help in the case of non-hw-accelerated content the cases are quite pricey the PSU one has to get ranges between 100/150 €/$ minimum to keep the noise down a low-mid build, all included, sums up to over 650 €/$ for a still-looking-ugly-unit, without the blu-ray drive. Please help. What do you advise on this? ;) Am I ignoring laptops too much, maybe? Are low-priced Acers that noisy/high pitched under full load?

• mplayer (mplayerhq.hu) repeats ending audio frames

  - by kamikatze

  mplayer (from mplayerhq.hu) on windows repeats the last few audio frames upon exit. When the video ends, before you can see Exiting...

• AviSynth ChangeFPS: combining videos with different framerates

  - by Daniel Saner

  I have two video recordings of the same scene, but with different framerates, that I would like to combine using an AviSynth script. One video is recorded at 30fps, the other at 120fps. What I would like to do is to keep them temporally synchronised, meaning that for each frame of the 30fps video, the output should display 4 frames from the 120fps video. I would like the final output video to play at 30fps so that the duration is 4 times the original recordings. From AviSynth's documentation, it seems ChangeFPS is the function I'll need, since it removes and duplicates frames, while 'AssumeFPS' just changes the playback speed (and my plan is basically to quadruple every frame of the 30fps clip). However, the filter does not seem to do what it says. If I try: clip30 = AviSource("0326.avi").ChangeFPS(120) clip120 = AviSource("0326-120fps.avi") it doesn't affect the playback speed or frame count of the 30fps clip at all, but removes every fourth frame from the 120fps clip, which is not at all what I want. Unfortunately, appending .ChangeFPS(7.5) to the clip120 instead does not have the same inverse effect—in that case, it does exactly what's to be expected. Alternatively, if I try: clip30 = AviSource("0326.avi").AssumeFPS(7.5) clip120 = AviSource("0326-120fps.avi") there is no effect at all, both clips are played back at 30fps, meaning that only a quarter of the 120fps clip has been shown by the time the 30fps clip is over. So how can I combine these two clips in the manner I want? I was unable to find any other internal or external filters that would help me do that. It seems to me that if ChangeFPS did what the manual says, it would be the right one for the job.

• Opening Skype, Opera, OpenOffice logs me off

• Queued Loadtest to remove Concurrency issues using Shared Data Service in OpenScript

  - by stefan.thieme(at)oracle.com

  Queued Processing to remove Concurrency issues in Loadtest ScriptsSome scripts act on information returned by the server, e.g. act on first item in the returned list of pending tasks/actions. This may lead to concurrency issues if the virtual users simulated in a load test scenario are not synchronized in some way.As the load test cases should be carried out in a comparable and straight forward manner simply cancel a transaction in case a collision occurs is clearly not an option. In case you increase the number of virtual users this approach would lead to a high number of requests for the early steps in your transaction (e.g. login, retrieve list of action points, assign an action point to the virtual user) but later steps would be rarely visited successfully or at all, depending on the application logic.A way to tackle this problem is to enqueue the virtual users in a Shared Data Service queue. Only the first virtual user in this queue will be allowed to carry out the critical steps (retrieve list of action points, assign an action point to the virtual user) in your transaction at any one time.Once a virtual user has passed the critical path it will dequeue himself from the head of the queue and continue with his actions. This does theoretically allow virtual users to run in parallel all steps of the transaction which are not part of the critical path.In practice it has been seen this is rarely the case, though it does not allow adding more than N users to perform a transaction without causing delays due to virtual users waiting in the queue. N being the time of the total transaction divided by the sum of the time of all critical steps in this transaction.While this problem can be circumvented by allowing multiple queues to act on individual segments of the list of actions, e.g. per country filter, ends with 0..9 filter, etc.This would require additional handling of these additional queues of slots for the virtual users at the head of the queue in order to maintain the mutually exclusive access to the first element in the list returned by the server at any one time of the load test. Such an improved handling of multiple queues and/or multiple slots is above the subject of this paper.Shared Data Services Pre-RequisitesStart WebLogic Server to host Shared Data ServicesYou will have to make sure that your WebLogic server is installed and started. Shared Data Services may not work if you installed only the minimal installation package for OpenScript. If however you installed the default package including OLT and OTM, you may follow the instructions below to start and verify WebLogic installation.To start the WebLogic Server deployed underneath of Oracle Load Testing and/or Oracle Test Manager you can go to your Start menu, Oracle Application Testing Suite and select the Restart Oracle Application Testing Suite Application Service entry from the Tools submenu.To verify the service has been started you can run the Microsoft Management Console for Services by Selecting Run from the Start Menu and entering services.msc. Look for the entry that reads Oracle Application Testing Suite Application Service, once it has changed it status from Starting to Started you can proceed to verify the login. Please note that this may take several minutes, I would say up to 10 minutes depending on the strength of your CPU horse-power.Verify WebLogic Server user credentialsYou will have to make sure that your WebLogic Server is installed and started. Next open the Oracle WebLogic Server Adminstration Console on http://localhost:8088/console.It may take a while until the application is deployed and started. It may display the following until the Administration Console has been deployed on the fly.Afterwards you can login using the username oats and the password that you selected during install time for your Application Testing Suite administrative purposes.This will bring up the Home page of you WebLogic Server. You have actually verified that you are able to login with these credentials already. However if you want to check the details, navigate to Security Realms, myrealm, Users and Groups tab.Here you could add users to your WebLogic Server which could be used in the later steps. Details on the Groups required for such a custom user to work are exceeding this quick overview and have to be selected with the WebLogic Server Adminstration Guide in mind.Shared Data Services pre-requisites for Load testingOpenScript Preferences have to be set to enable Encryption and provide a default Shared Data Service Connection for Playback.These are pre-requisites you want to use for load testing with Shared Data Services.Please note that the usage of the Connection Parameters (individual directive in the script) for Shared Data Services did not playback reliably in the current version 9.20.0370 of Oracle Load Testing (OLT) and encryption of credentials still seemed to be mandatory as well.General Encryption settingsSelect OpenScript Preferences from the View menu and navigate to the General, Encryption entry in the tree on the left. Select the Encrypt script data option from the list and enter the same password that you used for securing your WebLogic Server Administration Console.Enable global shared data access credentialsSelect OpenScript Preferences from the View menu and navigate to the Playback, Shared Data entry in the tree on the left. Enable the global shared data access credentials and enter the Address, User name and Password determined for your WebLogic Server to host Shared Data Services.Please note, that you may want to replace the localhost in Address with the hosts realname in case you plan to run load tests with Loadtest Agents running on remote systems.Queued Processing of TransactionsEnable Shared Data Services Module in Script PropertiesThe Shared Data Services Module has to be enabled for each Script that wants to employ the Shared Data Service Queue functionality in OpenScript. It can be enabled under the Script menu selecting Script Properties. On the Script Properties Dialog select the Modules section and check Shared Data to enable Shared Data Service Module for your script. Checking the Shared Data Services option will effectively add a line to your script code that adds the sharedData ScriptService to your script class of IteratingVUserScript.@ScriptService oracle.oats.scripting.modules.sharedData.api.SharedDataService sharedData;Record your scriptRecord your script as usual and then add the following things for Queue handling in the Initialize code block, before the first step and after the last step of your critical path and in the Finalize code block.The java code to be added at individual locations is explained in the following sections in full detail.Create a Shared Data Queue in InitializeTo create a Shared Data Queue go to the Java view of your script and enter the following statements to the initialize() code block.info("Create queueA with life time of 120 minutes");sharedData.createQueue("queueA", 120);This will create an instantiation of the Shared Data Queue object named queueA which is maintained for upto 120 minutes.If you want to use the code for multiple scripts, make sure to use a different queue name for each one here and in the subsequent steps. You may even consider to use a dynamic queueName based on filters of your result list being concurrently accessed.Prepare a unique id for each IterationIn order to keep track of individual virtual users in our queue we need to create a unique identifier from the virtual user id and the used username right after retrieving the next record from our databank file.getDatabank("Usernames").getNextDatabankRecord();getVariables().set("usernameValue1","VU_{{@vuid}}_{{@iterationnum}}_{{db.Usernames.Username}}_{{@timestamp}}_{{@random(10000)}}");String usernameValue = getVariables().get("usernameValue1");info("Now running virtual user " + usernameValue);As you can see from the above code block, we have set the OpenScript variable usernameValue1 to VU_{{@vuid}}_{{@iterationnum}}_{{db.Usernames.Username}}_{{@timestamp}}_{{@random(10000)}} which is a concatenation of the virtual user id and the iterationnumber for general uniqueness; as well as the username from our databank, the timestamp and a random number for making it further unique and ease spotting of errors.Not all of these fields are actually required to make it really unique, but adding the queue name may also be considered to help troubleshoot multiple queues.The value is then retrieved with the getVariables.get() method call and assigned to the usernameValue String used throughout the script.Please note that moving the getDatabank("Usernames").getNextDatabankRecord(); call to the initialize block was later considered to remove concurrency of multiple virtual users running with the same userid and therefor accessing the same "My Inbox" in step 6. This will effectively give each virtual user a userid from the databank file. Make sure you have enough userids to remove this second hurdle.Enqueue and attend Queue before Critical PathTo maintain the right order of virtual users being allowed into the critical path of the transaction the following pseudo step has to be added in front of the first critical step. In the case of this example this is right in front of the step where we retrieve the list of actions from which we select the first to be assigned to us.beginStep("[0] Waiting in the Queue", 0);{info("Enqueued virtual user " + usernameValue + " at the end of queueA");sharedData.offerLast("queueA", usernameValue);info("Wait until the user is the first in queueA");String queueValue1 = null;do {// we wait for at least 0.7 seconds before we check the head of the// queue. This is the time it takes one user to move through the// critical path, i.e. pass steps [5] Enter country and [6] Assign// to meThread.sleep(700);queueValue1 = (String) sharedData.peekFirst("queueA");info("The first user in queueA is currently: '" + queueValue1 + "' " + queueValue1.getClass() + " length " + queueValue1.length() );info("The current user is '"+ usernameValue + "' " + usernameValue.getClass() + " length " + usernameValue.length() + ": indexOf " + usernameValue.indexOf(queueValue1) + " equals " + usernameValue.equals(queueValue1) );} while ( queueValue1.indexOf(usernameValue) < 0 );info("Now the user is the first in queueA");}endStep();This will enqueue the username to the tail of our Queue. It will will wait for at least 700 milliseconds, the time it takes for one user to exit the critical path and then compare the head of our queue with it's username. This last step will be repeated while the two are not equal (indexOf less than zero). If they are equal the indexOf will yield a value of zero or larger and we will perform the critical steps.Dequeue after Critical PathAfter the virtual user has left the critical path and complete its last step the following code block needs to dequeue the virtual user. In the case of our example this is right after the action has been actually assigned to the virtual user. This will allow the next virtual user to retrieve the list of actions still available and in turn let him make his selection/assignment.info("Get and remove the current user from the head of queueA");String pollValue1 = (String) sharedData.pollFirst("queueA");The current user is removed from the head of the queue. The next one will now be able to match his username against the head of the queue.Clear and Destroy Queue for FinishWhen the script has completed, it should clear and destroy the queue. This code block can be put in the finish block of your script and/or in a separate script in order to clear and remove the queue in case you have spotted an error or want to reset the queue for some reason.info("Clear queueA");sharedData.clearQueue("queueA");info("Destroy queueA");sharedData.destroyQueue("queueA");The users waiting in queueA are cleared and the queue is destroyed. If you have scripts still executing they will be caught in a loop.I found it better to maintain a separate Reset Queue script which contained only the following code in the initialize() block. I use to call this script to make sure the queue is cleared in between multiple Loadtest runs. This script could also even be added as the first in a larger scenario, which would execute it only once at very start of the Loadtest and make sure the queues do not contain any stale entries.info("Create queueA with life time of 120 minutes");sharedData.createQueue("queueA", 120);info("Clear queueA");sharedData.clearQueue("queueA");This will create a Shared Data Queue instance of queueA and clear all entries from this queue.Monitoring QueueWhile creating the scripts it was useful to monitor the contents, i.e. the current first user in the Queue. The following code block will make sure the Shared Data Queue is accessible in the initialize() block.info("Create queueA with life time of 120 minutes");sharedData.createQueue("queueA", 120);In the run() block the following code will continuously monitor the first element of the Queue and write an informational message with the current username Value to the Result window.info("Monitor the first users in queueA");String queueValue1 = null;do {queueValue1 = (String) sharedData.peekFirst("queueA");if (queueValue1 != null)info("The first user in queueA is currently: '" + queueValue1 + "' " + queueValue1.getClass() + " length " + queueValue1.length() );} while ( true );This script can be run from OpenScript parallel to a loadtest performed by the Oracle Load Test.However it is not recommend to run this in a production loadtest as the performance impact is unknown. Accessing the Queue's head with the peekFirst() method has been reported with about 2 seconds response time by both OpenScript and OTL. It is advised to log a Service Request to see if this could be lowered in future releases of Application Testing Suite, as the pollFirst() and even offerLast() writing to the tail of the Queue usually returned after an average 0.1 seconds.Debugging QueueWhile debugging the scripts the following was useful to remove single entries from its head, i.e. the current first user in the Queue. The following code block will make sure the Shared Data Queue is accessible in the initialize() block.info("Create queueA with life time of 120 minutes");sharedData.createQueue("queueA", 120);In the run() block the following code will remove the first element of the Queue and write an informational message with the current username Value to the Result window.info("Get and remove the current user from the head of queueA");String pollValue1 = (String) sharedData.pollFirst("queueA");info("The first user in queueA was currently: '" + pollValue1 + "' " + pollValue1.getClass() + " length " + pollValue1.length() );ReferencesOracle Functional Testing OpenScript User's Guide Version 9.20 [E15488-05]Chapter 17 Using the Shared Data Modulehttp://download.oracle.com/otn/nt/apptesting/oats-docs-9.21.0030.zipOracle Fusion Middleware Oracle WebLogic Server Administration Console Online Help 11g Release 1 (10.3.4) [E13952-04]Administration Console Online Help - Manage users and groupshttp://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e13952/taskhelp/security/ManageUsersAndGroups.htm

• How to associate newly created SurfaceHolder to MediaPlayer

  - by fayerth

  In my code, I want to be able to temporarily hide (and subsequently show) a video. I am using a SurfaceView + MediaPlayer combination instead of the VideoView due to requirements. However, I am facing difficulties in getting video playback to occur as expected after I show the SurfaceView. My code excerpts includes the following: public void show() { if (mSurface != null) mSurface.setVisibility(View.VISIBLE); } public void hide() { if (mSurface != null) { if (isInPlaybackState()) pause(); mSurface.setVisibility(View.INVISIBLE); } } @Override public void surfaceCreated(final SurfaceHolder holder) { mHolder = holder; openVideo(); } @Override public void surfaceDestroyed(final SurfaceHolder holder) { // After this, the surface can't be used again mHolder = null; } private void openVideo() { if (mAssetPath == null || !mAssetPath.isEmpty() || mHolder == null) { // Not ready yet; try again later return; } // Pause music playback service Intent i = new Intent("com.android.music.musicservicecommand"); i.putExtra("command", "pause"); getActivity().sendBroadcast(i); if (mPlayer == null) { initializePlayer(); } else { mPlayer.setDisplay(mHolder); } } Based on the above, when I call hide(), surfaceDestroyed(SurfaceHolder) gets triggered. When I later call show(), surfaceCreated(SurfaceHolder) gets triggered, which will call openVideo() and associate the player with the newly provided SurfaceHolder. The above works as expected, and I believe this should be the correct process; however, when I call mPlayer.start(), I would hear the video's audio playing without any video and see the following error messages (which eventually causes the media playback to stop and complete, as noted by the disconnect logs): 10-23 11:29:42.775: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.795: E/MediaPlayer(4204): Error (-38,0) 10-23 11:29:42.805: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.810: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.810: V/MediaPlayer(4204): callback application 10-23 11:29:42.810: V/MediaPlayer(4204): back from callback 10-23 11:29:42.825: E/MediaPlayer(4204): Error (1,-2147483648) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer-JNI(4204): getCurrentPosition: 671668 (msec) 10-23 11:29:42.850: V/MediaPlayer(4204): message received msg=100, ext1=1, ext2=-2147483648 10-23 11:29:42.850: E/MediaPlayer(4204): error (1, -2147483648) 10-23 11:29:42.850: V/MediaPlayer(4204): callback application 10-23 11:29:42.850: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): stop 10-23 11:29:42.875: V/MediaPlayer(4204): stop 10-23 11:29:42.875: E/MediaPlayer(4204): stop called in state 0 10-23 11:29:42.875: V/MediaPlayer(4204): message received msg=100, ext1=-38, ext2=0 10-23 11:29:42.875: E/MediaPlayer(4204): error (-38, 0) 10-23 11:29:42.875: V/MediaPlayer(4204): callback application 10-23 11:29:42.875: V/MediaPlayer(4204): back from callback 10-23 11:29:42.875: V/MediaPlayer-JNI(4204): reset 10-23 11:29:42.875: V/MediaPlayer(4204): reset 10-23 11:29:42.900: V/MediaPlayer-JNI(4204): release 10-23 11:29:42.900: V/MediaPlayer(4204): setListener 10-23 11:29:42.900: V/MediaPlayer(4204): disconnect 10-23 11:29:42.910: V/MediaPlayer(4204): destructor 10-23 11:29:42.910: V/MediaPlayer(4204): disconnect Has anyone encountered this issue before and found a workaround?

• DirectX works for 64-bit but not 32-bit

  - by dtbarne

  I'm trying to play a game (Civilization 5) which was previously working but no longer. I believe I've narrowed it down to a DirectX issue because I get an error running dxdiag.exe in 32 bit mode. My goal (at least I believe) is to get Direct3D Acceleration "Enabled" in dxdiag (as it is in 64 bit dxdiag). A very similar issue is here: http://answers.microsoft.com/en-us/windows/forum/windows_7-gaming/direct3d-acceleration-is-not-available-in-windows/4c345e6e-dc68-e011-8dfc-68b599b31bf5?page=1 The proposed answer, which looks very promising, doesn't seem to work for me. Like other users in that thread, HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D\Drivers does not have a SoftwareOnly key to change. I even tried manually adding it as a string and dword, to no avail. I have a NVIDIA GeForce GT 525M, and before you ask, yes I've tried updating (also uninstalling, reinstalling) my drivers. I've also tried doing the same with DirectX (and Civilization 5 for that matter). Been debugging for some 4+ hours now after a full day of work and I've run out of ideas. I'm hoping somebody knows the solution here! :) Here's what I see when I open dxdiag: DxDiag has detected that there mgiht have been a problem accessing Direct3D the last time this program was used. Would you like to bypass Direct3D this time? No - Crash Yes - Works, but in Display tab: DirectDraw Acceleration: Disabled Direct3D Acceleration: Not Available AGP Texture Acceleration: Not Available If I click "Run 64-bit DxDiag", all three are "Enabled". I should also note that I've tried the following steps as Microsoft suggests, but I'm not able to do so as the "Change Settings" button is disabled. Some programs run very slowly—or not at all—unless Microsoft DirectDraw or Direct3D hardware acceleration is turned on. To determine this, click the Display tab, and then under DirectX Features, check to see whether DirectDraw, Direct3D, and AGP Texture Acceleration appear as Enabled. If not, try turning on hardware acceleration. Click to open Screen Resolution. Click Advanced settings. Click the Troubleshoot tab, and then click Change settings. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. Move the Hardware Acceleration slider to Full.

• No HDMI Audio with GeForce 9600GT and nForce board

  - by Bobby

  I've been trying to get HDMI with sound working for the last few days, and I'm a little bit out of ideas. (I've verified that the hardware/Setup works via Windows.) aplay does not list my HDMI device: $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: NVidia [HDA NVidia], device 1: ALC662 rev1 Digital [ALC662 rev1 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 I've already compiled the alsa drivers (1.0.24) from a snapshot (with --with-oss=no) and added the line options snd-hda-intel model=auto # Tried 3stack-dig and 6stack-dig too to /etc/modprobe.d/alsa-base.conf. Still, the device does not show up. If it is important, the HDMI TV is at the moment not configured to be part of the X session (I've tried that to, at least with X restart, and it didn't change anything).

• Getting Audio from a Zone

  - by bleonard

  Now that I have Firefox and Java Web Start running from a zone, the last piece of the puzzle was audio (essential because most Flash content is accompanied by sound).  In the global zone there's a nice little utility called audiotest for testing your sound: bleonard@solaris:~$ audiotest Sound subsystem and version: SunOS Audio 4.0 (0x00040003) Platform: SunOS 5.11 snv_151a i86pc *** Scanning sound adapter #1 *** /dev/sound/audio810:0dsp (audio engine 0): audio810#0 - Performing audio playback test... <left> ................OK <right> ...............OK <stereo> ..............OK <measured sample rate 47727.00 Hz (-0.57%)> *** All tests completed OK *** Of course, before you can try audiotest in a zone, it must be installed: root@myzone:~# pkg install audio-utilities Packages to install: 1 Create boot environment: No DOWNLOAD PKGS FILES XFER (MB) Completed 1/1 6/6 0.4/0.4 PHASE ACTIONS Install Phase 20/20 PHASE ITEMS Package State Update Phase 1/1 Image State Update Phase 2/2 However, we'll need to do more than just install audiotest: root@myzone:~# audiotest /dev/mixer: No such file or directory The device file is missing from /dev. The audio devices also need to be added to the zone. For this we modify the zone configuration as follows: bleonard@solaris:~$ sudo zonecfg -z myzone Password: zonecfg:myzone> add device zonecfg:myzone:device> set match=/dev/audio* zonecfg:myzone:device> end zonecfg:myzone> add device zonecfg:myzone:device> set match=/dev/sound/* zonecfg:myzone:device> end zonecfg:myzone> add device zonecfg:myzone:device> set match=/dev/mixer* zonecfg:myzone:device> end zonecfg:myzone> add device zonecfg:myzone:device> set match=/dev/sndstat zonecfg:myzone:device> end zonecfg:myzone> verify zonecfg:myzone> exit Then reboot the zone: bleonard@solaris:~$ sudo zoneadm -z myzone reboot After which, audiotest should work: root@myzone:~# audiotest Sound subsystem and version: SunOS Audio 4.0 (0x00040003) Platform: SunOS 5.11 snv_151a i86pc *** Scanning sound adapter #1 *** /dev/sound/audio810:0dsp (audio engine 0): audio810#0 - Performing audio playback test... <left> ................OK <right> ...............OK <stereo> ..............OK <measured sample rate 48208.00 Hz (0.43%)> *** All tests completed OK *** You can also examine /dev/sndstat for additional information: root@myzone:~# cat /dev/sndstat SunOS Audio Framework Audio Devices: 0: audio810#0 Intel AC'97, ICH (DUPLEX) Mixers: 0: audio810#0 Intel AC'97, ICH AC'97 codec: SigmaTel STAC9700 However, when testing the sound from Firefox (from a user account other than root), such as this recent Flash presentation on Solaris availability, you may still be disappointed. This is simply a permissions problem, as the devices only have read and write permissions for root: root@myzone:~# ls -l /dev/audio* crw------- 1 root root 99, 3 Jul 1 10:21 /dev/audio crw------- 1 root root 99, 4 Jul 1 10:21 /dev/audioctl To address this: root@myzone:~# chmod 777 /dev/audio* root@myzone:~# chmod 777 /dev/sound/* And you should be all set.
