• External SATA drive does not work without the optional USB cable *also* connected

  - by Software Monkey

  I have Vantec NST-260SU external eSATA/USB drive enclosure (which came with an optional separate power supply) connected to a relatively new Windows 7 computer. The drive should work as a SATA drive with either the separate power supply or using a USB cable solely for power. I would prefer to use the external power supply because I have used all my rear USB ports. Now, if I connect both the eSATA and USB cable, then: The drive shows in the BIOS list of AHCI drives (and not in the list of attached USB devices). Everything I can see about it in Computer Management seems to show it as a SATA driver (for example, it shows as "Location 0 (Channel 5, Target 0, Lun 0)" like my other SATA drives (and not "on USB Mass Storage Device" like my USB flash-drives). It seems very fast, very much faster than my USB flash drives. However, if I disconnect the USB cable and attach the power adapter instead, the drive does not show in the BIOS list and cannot be seen by Windows. The power LED on the enclosure is lit, and the drive enclosure becomes warm after running for a bit, so I am sure it is receiving power. Does anyone know if this device requires both the USB and eSATA cable, and if so, why? Or is there possibly something I need to do to reset the enclosure to not need the USB - the install instructions are pretty clear that you must connect the SATA cable before connecting the USB cable in order for the drive to function as SATA, which I am sure I did. PS: I have reviewed the small manual which came with it, which has not been of help.

• Display issue with fresh install of windows server 2012

  - by Tony

  I installed windows server 2012 last night on my home "server". I use server loosely. From the get go I had display and graphic issues. The image was fuzzy and jumbled up during the install. This continued once booted into the install. I did installed Server 2012 twice now as the first time, I only installed "core". I know this is not a busted graphics card because it worked fine in Win7, during boot, and fine in "core" mode. Once booted into "GUI" install of Server 2012, the image was messed up again. To make things even more weird, the windows "loading" screen looks fine. Once the login screen appears the image is fuzzy and jumbled. My guess was that it was a driver issue. I did try to install the win8 x64 drivers from nvidia. This caused the system to become unbootable and I had to restore to a previous working point and uninstall the driver. I did try two different monitors and cables. Also both ports on the back of the video card. I did manage to get RDP running and that works fine. I rarely work directly on this machine but it would be nice to have the option back. Geforce 210, AMD 4600+, 4 gigs of ram.

• Software raid 0 with six disks performance

  - by user134880

  I have some problems with disk performance. I have 6 x WD 500Gb RE4 disks. Each disk gives 135Mb/sec throughput. All measurements are made with hdparm with options "-tT" (I know that it is just synthetic test, but I need some start point to make measurements). I have controller with Sil3124 x 4 ports PCI Express 1x So... RAID0 on controller with 2 disks gives 200Mb/s - ok, pcie limit. RAID0 on motherboard with 2 disks gives 270Mb/s - niceeee :) RAID0 on contorller with 4 disks gives 200Mb/s - ok, pcie limit. RAID0 on controller with 4 disks + 1 disks on motherboard = 340Mb/s ... :( RAID0 on controller with 4 disks + 2 disks on motherboard = 300Mb/s .... why? Any ideas? Maybe need more cpu power? Now there is Pentium D Dual core 2.8Ghz, 4Gb RAM. It is dedicated box for storage.. no other activity.

• Capabilities of business and SOHO routers

  - by Q8Y

  I'm currently studying for the CCNA certifications (especially for Cisco routers and configuration). I know that business routers provide more features than SOHO routers, the processing speed and RAM can be enough. Assume I need to connect a number of users through a network (accessing internet, share files, printers, ...). I have a high speed connection to the internet and I already applied QoS. How can I find out how many users such a single (SOHO) router could handle? In my case I'd attach to it multiple switches until I have the number of ports needed. Would everything work well and smoothly with 50 users? What about 300? At which point would I need a business router instead? If I implemented VLAN here, would it make any difference in the performance? When do I really need to use more than one router? (Both SOHO and business) I'm thinking that I may need them only if I want to increase the performance (instead of replacing the existing one) and if I have multiple locations, so in this situation I need to have multiple routers, right? Put differently: Is there is a need to have another router if my business all in one place?

• DVI splitter not working as expected/confusion between DVI-D and -I

  - by Freakishly

  Hey guys, thanks for looking. I have an ATI FirePro™ V3700 in my desktop machine, and I have been running a dual-monitor setup quite effortlessly, thanks to the two DVI ports on the card. I came upon a third monitor, and wanted to extend my desktop to 3 screens, so I purchased a DVI splitter from Amazon. Now, I can only duplicate the second monitor onto the third, not extend it. I've tried all possible combinations of input to no avail. Here's the setup: The ATI FirePro™ V3700 has two Dual-Link DVI-I outputs The splitter splits a single Dual-Link DVI-I port into two Dual-Link DVI-I outputs Two of the monitors are NEC E222W, and the third monitor is a Dell 2001FP. Each monitor has one D-Sub and one Dual-Link DVI-D input. Cables going from the video card to the monitors are two Dual-Link DVI-D to the NECs and one Single-Link DVI-D to the Dell. Is the problem likely with the DVI-D/DVI-I mismatch? Or is it with the cable on the Dell that is only a Single-Link? The cables are easily replaceable, the monitors not so much. Thanks for your time, I really appreciate it. http://www.amd.com/us/products/workstation/graphics/ati-firepro-3d/v3700/Pages/v3700-specs.aspx http://www.amazon.com/Cables-Unlimited-DVI-D-Splitter-PCM-2260/product-reviews/B000H09RFM/ref=dp_top_cm_cr_acr_txt?ie=UTF8&showViewpoints=1 www dot newegg dot com/Product/Product.aspx?Item=N82E16824002495 accessories dot us dot dell dot com/sna/PopupProductDetail.aspx?cs=19&l=en&c=us&sku=320-1578 Apologies for the fudged links, I'm new here and they won't let me post more than two :P

• A router that supports connecting with 2 different wifi networks

  - by Allan Deamon

  I Have the following setup in one place: We have a small local ISP through wireless. I have a external parabolic antenna, connected to a external usb wifi radio, connected through USB to a desktop old PC. The pc connects do the ISP wiki network, then do a Dial Up (PPPoE) connection through the this wifi setup. This will expand with others mobiles devices to be used. When I need, I take my home wireless router and connect though Ethernet in the PC, which is shares the internet. The problem is that the PC must be always ON and working. I would like to buy a wireless router which could be an AP to the mobile devices, notebooks, etc, as also could connect to the ISP Wifi/PPPoE network. So, this device must: Have one radio with detachable antenna to connect to the external antenna. It must connect as client to a network and then dial up the PPP Have another radio serving as AP (infrastructure) to the local place This can't be very expensive. I found a candidate: ( http://www.tp-link.com/en/products/details/?categoryid=1682&model=TL-WR2543ND ) It have 3 deatachable antennas, working with dual band. Officially, his firmware doesn't support it. My supposition: If internally there is 3 or 2 distinct wlan ports (like wlan0, wlan1), and there is support, i could use a OpenWRT, DD-WRT or Tomato to make this works. It also have 1 USB port, which I cold use to connect my actual USB Wifi card on it instead to the old PC. Another alternative, is a router that can do this out of box, with the original firmware. But I don't think this is a easy thing to find.

• Wired to wireless bridge in Linux

  - by adrianmcmenamin

  I am attempting to set up my Raspberry Pi as a bridge (but I think this is not a question specific to the hardware) - using Debian wheezy. I have a hostapd.conf: (some details changed for security)... interface=wlan0 bridge=br0 driver=nl80211 auth_algs=1 macaddr_acl=0 ignore_broadcast_ssid=0 logger_syslog=-1 logger_syslog_level=0 hw_mode=g ssid=MY_SSID channel=11 wep_default_key=0 wep_key0=MY_KEY wpa=0 (yes, I know WEP is no good) And this in /etc/network/interfaces auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 iface wlan0 inet manual wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf iface default inet dhcp auto br0 iface br0 inet dhcp bridge-ports eth0 wlan0 Everything seems to come up ok, but I cannot associate with the bridged wireless connection - even though the flashing lights on the USB stick suggest packets are being exchanged. I have read somewhere that not all cards/devices will run in hostap mode - they won't pass packets in one direction: is that right? (The info was a bit old)- this my card: [ 3.663245] usb 1-1.3.1: new high-speed USB device number 5 using dwc_otg [ 3.794187] usb 1-1.3.1: New USB device found, idVendor=0cf3, idProduct=9271 [ 3.804321] usb 1-1.3.1: New USB device strings: Mfr=16, Product=32, SerialNumber=48 [ 3.816994] usb 1-1.3.1: Product: USB2.0 WLAN [ 3.823790] usb 1-1.3.1: Manufacturer: ATHEROS [ 3.830645] usb 1-1.3.1: SerialNumber: 12345 So, what have I got wrong here?

• Configure linux machine as bridge/switch and end device

  - by leemes

  At my home, I have two desktop PCs in two rooms. The router / DSL modem is in one of these rooms. Now I want to configure a home server (having 2 LAN ports, running 24/7) in the corridor between the two rooms, using only one LAN cable at each door. This gives me the following physical configuration: (door) (door) .----/-/----. .-----/-/----------._ FritzBox | | | .----´´ DSL Router PC1 Server | PC2 As just said, the server has 2 network interfaces and is running Ubuntu. What I need now is a network configuration which enables both the server and PC1 to connect to the router. I think the server needs to serve as a bridge or switch. Currently, all computers are configured having static IP addresses. If I'm understanding it correctly, a bridge / switch doesn't have its own IP address, but as the server needs to be configured as an own end device, it needs to have one. My first question is, do I have to configure both interfaces separately, giving both the same static IP address? My next question is, how do I bridge the two physical networks into one? I have basic understanding (but am always confused again and again) of bridges and switches, but I don't know how to configure it in software. I only know that it's possible to do so :) The third question is: Is it possible to configure this in a way that network packets from/to PC1 to/from the router only go through hardware or only consume low CPU in the server? Can you help me? Thanks in advance!

• How to prevent eMule from jamming up the router?

  - by the searcher

  Usually, when eMule is started, after some time, I find that the router is jammed, so the internet connection on that computer stopped working, or it seemed to be waiting for some port to be freed up before it can connect to a website. This sometimes affect even other PCs or Macs using the same router. Is there a way to prevent eMule from hogging too much resource or ports? I see that there is under Options -> Connection "Max Sources/File" and a "Connection Limits - Maximum Connections". Right now I set them to really low numbers: the first to 120 and the second to 200, but what are good numbers to fill in there so that it can work well without jamming up the router or use up the network resource of the PC or Mac? Or could it be that the number of files that are "Waiting" is too high, and used up too much resource? (If so, can emule automatically limit the number to 10 or 20 to prevent using too much resource?) (This happened before on Linksys router, Netgear router, and the AT&T U-verse router.)

• Port Forwarding to put my web server on The Internet

  - by Chadworthington

  I went to http://canyouseeme.org/ to check to see what my external IP address. Regardless of what port I enter, it tells me that the port is blocked. I have a LinkSys router that basically has the default settings with the exception that I have WEP encrptin setup and I have forwarded a few ports, including 80 and 69. I forwarded them to the 192.x.x.103 IP address of the PC which is running IIS. That PC runs Symantec Endpoint Protection, which I right mouse clicked in the tray to Disable. These steps used to make my PC visible so I could host my own web site in IIS on port 80, or some other port, like 69. Yet, the Open Port tool cannot see my IP when it checks eiether port and when I navigate to http://my external ip/ I get "page cant be displayed" At first I was thinking that maybe Comcast is blocking port 80, but 69 doesnt work eiether. I do not see any other blockking set up in my router and, as I mentioned, I went with teh defaults except where discussed. This is a corporate PC and Symantec End Point Protecion is new to it (this previously worked on teh same PC with Symantec Protection Agent), but I thought that disabling Sym End Pt from the tray, that that would effectively neutralize it. I do not have the rights to kill the program itself. Any suggestions on what else to try to make my PC externally visible?

• XenServer 5.5 running WHS.. trying to add local or network printer/scanner/copier

  - by ProstheticHead

  Hi guys. Just wondering if anyone has prior experience in sharing a multifunction printer across a (mostly windows) network? My situation at the minute is complicated.. I DID have the printer attached directly to a Windows Home Server box and was able to scan to a share and print across the network from my other computers. Compatibility problems have forced me to virtualize WHS on XenServer 5.5... This is actually quite useful because I can now run other things on the same box, but the problem is that now WHS doesn't get direct hardware access so it doesn't see a USB attached PSC... Grrrr! So now I have a choice to make. I've read somewhere that I can buy an add in PCI USB controller and somehow set up a passthrough to one VM at a time. To me, this sound complicated but if it's likely to work reliably I'd prefer this method. I've read about another approach, which I'm not sure about either, but I guess sounds plausible. A Network USB server, (NOT a print server) that can somehow make a USB port accessible across a network. My worry here is that it likely needs some kind of 3rd party software to work.. so not ideal. If there are any other methods you can suggest I'd be happy to hear them... I need your help guys. I'm also in the market for a PCI express SATA controller, nothing flashy, just need up to 8 ports, JBOD and 100% compatability.. Any suggestions? Regards Kevin

• No Wireless Networks, BCM4313 [duplicate]

  - by TalonPlz

  This question already has an answer here: How to Install Broadcom Wireless Drivers (BCM43xx) 38 answers Just bought this little Asus 10 inch laptop that came with Ubuntu 12.04. Everything at my home was fine: Wireless identified and connected. As soon as I went to my girlfriend's house the trouble started. I couldn't connect to wireless (authentication... times out and asks for authentication) I started doing internet searching, tried a few solutions posted on line using terminal commands. No solutions. I decided to upgraded to 12.10-13.04 and that left me with a worse problem: I can no longer see ANY networks what so ever. Wireless card is ON, with out a doubt. Wired connection works.

• Windows Server 2008 - RAID 5 Fails on Reboot

  - by Adam

  Hey, I've got an install of Windows Server 2008 Enterprise. It's running software RAID-5 with five disks. The disks were originally formatted under Windows Server 2003, but came up fine once I installed Windows Server 2008. The issue I'm having is that every time I reboot the server, the RAID comes up with a "Failed Redundancy" - the data stays available. I have 4 disks on a PCI SATA controller, and one of the disks connected to the motherboard's on-board SATA ports. (The other on-board port has the system disk connected.) I was having Disk #4 fail consistently, so I tried swapping the cables on the controller end. I swapped the on-board RAID disk with one on the PCI controller. Same issue now, expect with disk #1. Once the system's up, I can reactivate the RAID, it will resync for a while, then go to "Healthy", and will stay that way for an indefinite amount of time - until I reboot. As soon as I reboot, the disk drops again. I've ruled out disk + cable with the recabling. I don't believe it would be the controller as it seems to work fine most of the time - only failing on reboot, and the other port on the same controller connects the system disk - which is clearly working. I did look in the event log, but didn't see anything particularly relevant (although I didn't know what I was looking for - just looked for anything with a "Warning" or "Error" symbol that looked disk-related :)). I'm not particularly familiar with RAID on Windows, does anyone have any idea why this might be doing this? Any idea how to fix it? Any suggestions appreciated! -- Adam

• How to host an ssh server?

  - by balki

  Hi, I have a broadband internet connection. I have an wireless modem (Airtel India). I don't have a static ip address. I want to host a ssh/web/ftp server to be visible to the outside world just for testing and learning purpose so I can ask my friend to connect to my current ip address and test. My modem has an admin interface which allows to port forward and open ports. I set up ssh server as shown and checked if port 22 is open using this website , Port Scan And port 22 is open. I have an openssh server running and it works if i do, ssh [email protected] which is my local ip address but doesn't work if i do ssh [email protected] where 122.xx.xx.xx is my external ip address of my modem which i checked from whatismyipaddress.com. Since it looks like the port is open, I wonder if there is some setting I need to change in my server config to expose my server. How should I go about solving this?

• Unable to connect to server after a certain amount of time

  - by Troy

  I am a business FIOS subscriber with 5 static IPs. I have the following network setup: Verizon provided ONT Dlink switch Dell server running Ubuntu 12.04 with iptables enabled and a static IP address. The makes/models of hardware are: FIOS ONT Alcatel-Lucent I-211M-H ONT D-Link D-Link Web Smart Switch DES-1228P Server Dell Optiplex 755 (Ubuntu 12.04 Server) I have iptables running on the server with http, https and ssh ports open. I can connect to a website on the server from an external computer, but after a certain amount of time (mins to hours), I can no longer connect. All I have to do to re-enable connectivity is connect to the server via SSH from a computer INSIDE the network. I don't have to actually login, I just have to establish a connection. I can then access the website externally again. I did some googling and it seems some of verizon's equipment had an ARP bug where the ARP entries would expire after a certain time period, but those issues all seem to be from back in 2009 - 2010. I know the switch has an 'auto learning Mac address' feature, but I'm not sure if that could be the problem or not. Does anyone have any ideas or advice on how I can troubleshoot this? Thanks!

• Apache Server Status page in port 8443

  - by batman

  I'm very new to apache. I tried to enable the server status page of apache. I added the status.conf and status.load to mods-enabled directory. I changed the config of apache2.conf to include all mods-enabled directory. This is the config of staus.conf: <IfModule mod_status.c> # # Allow server status reports generated by mod_status, # with the URL of http://servername/server-status # Uncomment and change the "192.0.2.0/24" to allow access from other hosts. # <Location /server-status> SetHandler server-status Order deny,allow Deny from all Allow from 127.0.0.1 ::1 # Allow from 192.0.2.0/24 </Location> # Keep track of extended status information for each request ExtendedStatus On # Determine if mod_status displays the first 63 characters of a request or # the last 63, assuming the request itself is greater than 63 chars. # Default: Off #SeeRequestTail On <IfModule mod_proxy.c> # Show Proxy LoadBalancer status in mod_status ProxyStatus On </IfModule> </IfModule> The default settings. I restarted my server. I'm redirecting all ports to 8443. Which in turn turns my requests to localhost:8443/server-status. Which does throw an 404 error. Are there any way to get around this? Thanks in advance.

• Server resolve issues not consistent

  - by bobthemac

  I am having some weird issues with my web server. It has a public ip address and is set-up on an openVZ virtual machine. Accessing in to the site works fine every time but when trying to access out from the server I can't always connect out. Sometimes I can connect out and resolve addresses, sometimes I can't. The issue is visible in both ssh when trying to do a wget command on Google; sometimes it works and I get the index.html page and sometimes I get nothing. The issue is more visible in wordpress where you can't view themes but after a few presses of the try again button you can then view them. I have searched google and found nothing about this issue. Does anyone here have any ideas what could be causing this strange behaviour? Ports 80 and 2222 are open for web and ssh.

When I launch a mapper only job using: hadoop jar /usr/lib/hadoop/contrib/streaming/hadoop-streaming*.jar -file /usr/src/mystuff/mapper.py -mapper /usr/src/mystuff/mapper.py -input /incoming/STBFlow/* -output testOP hadoop duly decides it will use 66 mappers on the cluster to process the data. The testOP directory is created on HDFS. A job_conf.xml file is created. But the job tracker UI at port 50030 never shows the job moving out of "pending" state and nothing else happens. CPU usage stays at zero. (the job is created though) If I give it a single file (instead of the entire directory) as input, same result (except Hadoop decides it needs 2 mappers instead of 66). I also tried using the "dumbo" Python utility and launching jobs using that: same result: permanently pending. So I am missing something basic: could someone help me out with what I should look for? The cluster is on Amazon EC2. Firewall issues maybe: ports are enabled explicitly, case by case, in the cluster security group.

• Expresscard Not Detected in PCI-E Adapter

  - by maxpower47

  I'm trying to put an expresscard TV tuner (Avermedia HC82) into my HTPC using this expresscard to PCI-E adapter. I've verified that the tuner works fine in my laptop. The motherboard is a Biostar TF7050-M2. When I install it and turn it on, the light on the back of the adapter comes on fine (there are two indicator lights on the back to show if it is using PCI-E or USB communication, USB communication goes through a USB cable connected between the card and a header on the motherboard) showing that it is working in PCI-E mode. However, the device is never detected in Windows 7 Professional x64. The auto detect never happens, it doesn't show up in the device manager, and I can have it rescan for new hardware and nothing is found. I tested the whole setup (tuner + adapter) in another PC (also using Win 7 Pro x64) and it worked fine. I also tried: Plugging the adapter in to the PCI-E x16 slot on the motherboard (I verified first that the x16 slot worked by installing a video card in it) Booting into safe mode and rescanning Updating the chipset drivers Installing the tuner drivers first Using a different USB cable, plugged in to one of the known good ports on the back of the board Trying it without the USB cable plugged in Removing the other PCI cards that were installed on the board Looking through the BIOS for any setting that might be disabling it somehow to no avail. I'm at a loss for what else to try. I really don't want to RMA it (the shipping back to newegg will be almost as much as it cost to buy in the first place. Any ideas?

• Issues Deploying Functional WAR to Elastic Beanstalk with Tomcat7

  - by BFar

  I am currently deploying OpenTripPlanner (http://github.com/OpenPlans/OpenTripPlanner.git) to Elastic Beanstalk. I'm able to successfully build and deploy opentripplanner with my own customized settings on an ec2. I have set it up so that the appropriate WAR file can be placed in the Tomcat/Webapps folder, and when Tomcat is started up, it will auto-deploy, and even download open trip planner's graph.obj from an S3. All of that works just fine, except when I try to deploy to Elastic Beanstalk. When I upload to Elastic Beanstalk, the log shows that my WAR file is successfully unpacked & successfully downloads the graph.obj from my S3. The only difference is that then nothing happens and I can't load the site in my browser. The health is RED, and I can't figure out what is going on. I've tried looking into ports and dns issues, but I can't determine what's wrong. Anyone have any ideas? Why would a WAR that works on tomcat7 outside of Beanstalk fail to be accessible?

• Two servers, two domains, one ip. mod_proxy beginner

  - by Gutsav

  I run two virtual web servers (both running apache2 on debian). I have just one external IP, but two domains, and I want a domain going to each of the servers. I've understood that I need a Reverse Proxy, and I enabled both the mod_proxy and the mod_proxy_http modules on the "primary server". Do I need to enable anything on the "secondary server"? I also understood that I need to write some things in a virtual host file, but what? On the primary server, I have a virtual host file for one of the domains, and some for subdomains. I want domain1.tld to go to the primary server (port 80 is forwarded to it, so that works) and domain2.tld to go to the other server (internal ip 192.168.0.x). No ports needs to be forwarded to it, right? So, what to add and in which virtual host file? Or a new one? Other questions suggest adding ProxyPass and ProxyPassReverse, but I'm lost anyway, and I just don't understand the apache documentation. Thanks in advance

• Syntax error on line 494 of httpd.conf: Cannot load .../php5apache2_2.dll into server

  - by pikachu

  I have been learning PHP. I had installed Apache-server (not in a combination-suite like USBWebserver). Now I'm trying to put my sites on a portable stick, using USBWebserver. I already used that program before to carry MySQL databases with me (and Apache worked as well, cause I used the included PHPMyAdmin for managing the databases.), but now it doesn't work anymore. When I start the program, I keep having the text saying Apache is offline. I've tried to open Apache using the command line (don't know what that would do, but, it's just a try). I got an error message saying Syntax error on line 494 of C:/.../httpd.conf: Cannot load C:/.../php5apache2_2.dll into server: (The following is translated from Dutch) An initialization routine of the dynamic link library (dll-file) has failed. Line 494 says this: LoadModule php5_module "C:/Users/School/Downloads/USBWebserver v8_en/php/php5apache2_2.dll" My first Apache installation (its service) is not running. The ports are different. And I also uninstalled the service (using the httpd.exe -k uninstall command); What can be the problem? Thanks for help.

• PC -> TV HDMI suddenly doesn't work, any other option does

  - by XSlicer

  So my parents wanted to connect their PC to their TV, so they bought a 10m (35 ft) cable. It all worked perfectly. Then my mom tripped over the cable, breaking it. She somehow got a free replacement, but at the same time some more expensive one from an uncle. Now the problem is that this suddenly doesn't work anymore (TV saying "Format not supported"). I've tried several other things to pinpoint the actual problem, but none brought me something conslusive: PC (hdmi) to TV doesn't work (both cables) PC (hdmi) to TV doesn't work (short cable) Laptop (hdmi) to TV work (same cables) BluRay (hdmi) to TV works (same cables) PC (hdmi) to monitor works (same cables) PC (DVI w/ adapter HDMI) to TV works (same cables) I've tried different ports, tried Linux, reinstalling drivers (the graphics card is internal using an i5 sandy bridge. Normally it's running Windows 7 Home Prem, the TV being a Philips 37PFL7605H). So basically, everything works, except that thing what we want. The only things I am thinking of is that the sound is interfering or that the HDMI-output is somehow broken. Or is it anything else? I'm kind of lost.
