  • How can I enable auto-switching HDMI sound on Ubuntu 12.04?

    - by João Ciocca
    I've just installed Ubuntu 12.04 on my Lenovo G550 notebook and decided to test the main thing I use it for, on Windows: watching movies and series on my living room TV. Plugged in the HDMI cable, screen auto-configured nicely - awesome. But the sound is coming through my notebook's speakers, instead of my TV. Searched for almost an hour on Google, found a couple of things - nothing that helped, though. Here are two links that made me sad: Another question on AskUbuntu "a better sounding world" post about HDMI On 2, David says that autoswitching was disabled... so how can I enable it?

    - by tam_ubuuser
    i am having an sony E series laptop.i have an HDMI port .at this stage ,i have tested my sound card , which provides audio out on my laptop i.e i could hear songs .my laptop has two sound cards amd 5450 and an intel-hda(alsamixer shows that as s/pdif) . i decided to connect HDMI output to my new HD-TV.but, i could get only visuals on my TV,NO AUDIO OUTPUT ( HDMI cable works fine with win 7).my laptop has two sound cards.but i couldn't switch output to other card.( i don't know ,how to do that) i decided to update alsa. complied the following code in terminal. sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily sudo apt-get update sudo apt-get install alsa-hda-dkms then,strangely no login sound, and no audio output on my laptop at all .then, started complied code from step1 sound troubleshooting procedure from offical ubuntu site.then, my speaker icon taskbar disappeared .obivously $aplay -l ,provided output as no soundcards detected . so , i implemented step 4 from that guide, it provides a output of all hardware devices in my laptop. *-multimedia UNCLAIMED description: Audio device product: Cedar HDMI Audio [Radeon HD 5400/6300 Series] vendor: Hynix Semiconductor (Hyundai Electronics) physical id: 0.1 bus info: pci@0000:01:00.1 version: 00 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi bus_master cap_list configuration: latency=0 resources: memory:f0040000-f0043fff *-multimedia UNCLAIMED description: Audio device product: 5 Series/3400 Series Chipset High Definition Audio vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 05 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: latency=0 resources: memory:f5e00000-f5e03fff that command displayed output name of the two cards . but , still i have no positive output on $aplay -l. so therfore, i think alsa couldn't detect my sound cards . is there solution to this problem? it could be better,if alsa would channel output from multiple sound cards ? how should install and configure alsa such that detects HDMI cable as soon i connect to my HD tv? is it possible to alsa and pluseaudio 2.0 to co-exist, if so how?

  • How can I add a custom item to the Sound Indicator?

    - by con-f-use
    One of the strength of Unity are the various standardized indicators. I want to customize the sound indicator with an additional menu entry that runs a small shell script. I'm not afraid of a little Python code and I hope someone can point me to the right subroutine in the right file. I suspect that will be fairly easy but all the indicators are just so bloated that I can't look through their code in a reasonable time. Any help is appreciated. I know it is possible as the marvelous Skype-Wrapper does it.

  • How to switch sound-drivers, and to which? [AMD] Hudson Azalia Controller

    - by Anders Martini
    System settings/sound does not open, freezes and I have to force close. Speaker symbol with volume control does not open scroll-down menu, and there is no sounds. Many people have problems with Hudson Azalia in Ubuntu, but I found no working solution. I don't really understand much of this, but here are some more details: aplay -l : **** List of PLAYBACK Hardware Devices **** (after running this one, it starts some kind of process that doesn't get any results, and doesn't stop, terminal has to be shut down) lspci -vnn | grep -iA5 audio: 00:01.1 Audio device [0403]: Advanced Micro Devices [AMD] nee ATI Device [1002:9902] Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at f0444000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel -- 00:14.2 Audio device [0403]: Advanced Micro Devices [AMD] Hudson Azalia Controller [1022:780d] (rev 01) Subsystem: Hewlett-Packard Company Device [103c:184c] Flags: bus master, slow devsel, latency 32, IRQ 54 Memory at f0440000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel It seems to me that I'm currently running hda Intel drivers on my AMD Hudson Azalia soundcard. I can't see what drivers this soundcard uses. Do I need any additional drivers for my soundcard, and where would I find them?

  • Why is my sound not working in Flash?

    - by animuson
    This is what I have as far as code, it is in the first frame of the movie. nature = new Sound(this); nature.attachSound("sound_naturally"); nature.setVolume(50); nature.start(0,0); nature.onSoundComplete = function(){ nature.start(0,0); } trace(nature); The trace outputs '[object Object]' at runtime. I have the sound exporting to ActionScript with the link identifier 'sound_naturally', not exported to the first frame. I don't understand why it's not working. I did like the exact same thing like 3 hours ago and it worked fine, but I lost the file so I had to redo it and now it won't work at all. Using Flash 10 with ActionScript 2.0

  • Sound not working in iPhone Simulator?

    - by pix0r
    Somehow my iPhone Simulator is unable to play sounds. First an app I'm working on using AudioServicesPlaySystemSound() stopped working.. I spent a while debugging this but sound is still working on the iPhone when I run the app on the device. I get the same results with other iPhone apps such as the sample Crash Landing app. I can't find a sound setting anywhere in the simulator or Xcode preferences. I've tried resetting the simulator through "Reset Content and Settings" menu item to no avail.

  • Bypass system sound setting objective c

    - by HiGuy Smith
    Hi. I have an app that Is supposed to play a AudioServicesPlayAlertSound(); but I've noticed on the iPod touch 1G, the sound will only play if the system sound setting is set to speaker or both. Is there a way to bypass this setting, because I know it works when the setting is not set to headphones. Also, if it is not possible, is there a way to alert the user to change this setting? I have a iPod touch 1G to test with, just incase. Wondering, HiGuy (CouleeApps)

  • Play sound in mobile browser?

    - by John
    I want to make myself a web based stop watch for training that I can use on my Blackberry mobile browser. The stopwatch should count 3 minutes, then ring a bell, wait 1 minute, then ring another bell and then repeat. My problem is I can't seem to get sound to work on my blackberry browser. I tried using <embed src="bell.wav"> which works fine in the browser of a normal computer, but it doesn't make a sound on my blackberry. Should I build this stopwatch with Javascript and HTML or should I build it with flash?

  • Randomly generate sound from onClick and onShake events?

    - by Aaron
    I've literally looked everywhere on the net and found very little clarification on how to do this. Pretty much, I have 8 sound files laid out in an array.xml file and I need to play a randomly chosen file ONCE per or onClick or onShake. First off, what technique should I use to achieve this? ARRAY-RANDOM- STRING-PLAY? RANDOM INT-PLAY? RANDOM INT-STRING-PLAY? Any kind of direction will help greatly cause I'm almost 3 weeks worth of research into this. *NOTE: MediaPlayer mp = MediaPlayer.create(JelloMan.this, R.raw.sound) ...is what I'm stuck on being you can't replace the "R.raw" part with a string...

  • trivial linux sound playback

    - by anon
    The classical C program is something like: int main() { fprintf(stderr, "hello world\n"); } a classical OpenGL program is: open up a window setup ortho view draw a colored triangle Now, I want to do the most basic thing for sound in Linux. I want to: 1) open up speakers 2) send a bunch of data, meant to be interpreted at 40Khz, 3) have pseakers play said data no midi, no instruments, ... just playing back raw data What is the easiest way to do this in a C program? [and what libraries; what's the equiv to OpenGL for sound?] Thanks!

  • Suggestion for creating custom sound recognition software to toggle audio

    - by Parrot owner
    I need to develop a program that toggles a particular audio track on or off when it recognizes a parrot scream or screech. The software would need to recognize a particular range of sounds and allow some variations in the range (as a parrot likely won't replicate its sreeches EXACTLY each time). Example: Bird screeches, no audio. Bird stops screeching for five seconds, audio track praising the bird plays. Regular chattering needs to be ignored completely, as it is not to be discouraged. I've heard of java libraries that have speech recognition with dictionaries built in, but the software would need to be taught the particular sounds that my particular parrot makes - not words or any random bird sound. In addition as I mentioned above, it would need to allow for slight variation in the sound, as the screech will likely never be 100% identical to the recorded version. What would be the best way to go about this/what language should I look into?

  • Sound sample recognition library/code

    - by Daniel Mošmondor
    I don't want sound-to-text software. What I need is the following: I'll record multiple (say 50+) audio streams (recordings of radio stations) from that recordings, I'll mark interesting audio clips - their length ranges from 2 to 60 seconds - there will be few thousands of such audio clips library should be able to find other instances of same audio clips from recorded sound streams confidence factor should be reported to used and additional input provided so the recognition could perform better next time Do you know of such software library? LGPL would be most valuable to me, but I can go for commercial license as well.

  • Windows 7 laptop's volume with headphones way too loud

    - by jcao219
    I have two headphones, neither has any amps or volume control, and both have the same problem with this computer. I normally have the volume on 10%, and that is optimal. I'm still very afraid that someday it will be at 100% and i'll accidentally have my headphones on. I tested how loud it is at maximum volume -- it's earsplittingly loud! In fact, it's so loud that if I lay the headphones down on the table, I can listen to a song perfectly clearly from meters away. Is there any way to make the volume control more safe for the ears?

  • Realtek "Microphone Effects" no longer working

    - by abc
    I have a mic plugged into my computer, and I was able to use the "microphone effects" tab here to enable/disable noise suppression and acoustic echo cancellation. Noise suppression off and acoustic echo cancellation on were the most recent settings I had on before the problem occurred. I disabled my mic in the windows 7 "recording devices" tab, then re-enabled it. When it came back, these options were grayed out, and remained so even after a reboot. I am not sure why this is or how to fix it, all other options are still the same (Settings are identical to when it was working). Any ideas whats wrong or how to fix it? edit: can't post image due to being new.

  • Ubuntu and surround sound

    - by keith
    I'm trying to connect my Logitech x.530 to my Dell studio 1558 and get 5.1 sound. I have 3 jacks and in Windows I automatically could switch between line in adn mic. Which means I could get 5.1 surround over these 3 jacks. Ubuntu does not realise that one of the three jacks should be switched to give sound to the center and LFE speaker. I tried all the tips in the forums, but nothing works. I can only select 4.0 sound in pulse audio. As the dell and the IDT 92hd89e chip for the sound are probably famous laptops I thought there must be someone who has similar issues in the 5.1 sound. I would like to stay at Linux but without this hardware support it's almost impossible.

  • Getting nice sound from Java

    - by Peter Lang
    I managed to play midi files using Java, but it produces some distracting noise. I figured out that this is caused by the poor quality soundbank file shipped with Java 6 SDK/JRE. How can I improve that quality? Here is what I have so far: MidiNote example using a Receiver works fine (sounds the same as when playing midi files with other players), so it does not seem to use the Soundbank shipped with Java but the fallback mechanism that uses a hardware MIDI port. Using SimpleMidiPlayer example to play a Midi file works, but the quality is poor. When I delete lib/audio/soundbank.gm, the quality is not bad any more, so the fallback is used again. When I put soundbank-deluxe.gm into the same directory, it is used and produces much better sound. Messing with the clients soundbank file as described in the official Installation Instructions certainly isn't an option, so I tried to put the new soundbank-file into the jar-file and load it: Soundbank soundbank = MidiSystem.getSoundbank( getClass().getResourceAsStream("soundbank-deluxe.gm")); if(synthesizer.isSoundbankSupported(soundbank)) { System.out.println(synthesizer.loadAllInstruments(soundbank)); } This prints true, but the sound remains unchanged. What am I doing wrong loading the soundbank file? Can I force the hardware MIDI port to be used instead of the standard soundbank file?

  • Notification doesn't play sound or show lights even though set to

    - by robintw
    In my android application I have the following code: Notification notification = new Notification(icon, tickerText, when); context = context.getApplicationContext(); CharSequence contentTitle = "UK Radio Guide"; CharSequence contentText = title + " on " + channel_id + " at " + start; Intent notificationIntent = new Intent(context, ViewSchedules.class); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); notification.ledARGB = 0xff00ff00; notification.ledOnMS = 300; notification.ledOffMS = 1000; notification.flags |= Notification.FLAG_SHOW_LIGHTS; notification.sound = Uri.parse("android.resource://com.robinwilson.radioguide/" +R.raw.chimes); notification.vibrate = new long[] { 0, 300, 200, 300, 400, 300 }; // Actually send the notification nm.notify(0, notification); As far as I am aware, I have followed the steps in the documentation to set it to play a sound from the resources folder, and to flash the lights. However, neither of these happen. It does, however, vibrate, as instructed. Any ideas what I'm doing wrong here? I've looked through the permissions that I can give the app in the AndroidManifest.xml file, but I can't see one for letting it flash the light or make sounds.

  • 5.1 sound in Unity3d 3.5

    - by N0xus
    I'm trying to implement 5.1 surround sound in my game. I've set Unity's AudioManager to a default of 5.1 surround and loaded in a 6 channel audio clip that should play a sound in each of the different audio spots. However, when I go to run my game, all I get is flat sound coming out of my front two speakers. Even then, these don't play the sound they should (front speaker should play "front speaker" right should play "right speaker" and so). Both speakers just end up playing the entire sound file. I've tried looking to see if there is a parameter that I have missed, but information on how to set up 5.1 sound in Unity is lacking (or my google skills aren't that good) and I can't get it to work as intended. Could someone please either tell me what I'm missing, or point me in the right direction? My audio source is situated at point (0, 0, 0) with my camera also being in the same point. I've moved about the scene but the same thing happens as I've already described.
