Ubuntu Multimedia :: VLC Always Changes The Output Device
Jul 23, 2011
I am using a sound card with the C-media CMI8788 chip. This card has both analog and digital outputs, which Linux sees as two different output devices.
The Problem I am having with VLC is that it always changes the output device in its settings to analog. I constantly have to be going into VLC advanced settings and picking Alsa: Digital for the output.
After that the sound outputs fine.
This only happens with VLC. All other programs on my pc output sound perfectly fine. I am using Lucid.
How can I set the default to be the digital output?

I'm using FFADO on JACK in order to use my firewire device (M-Audio Profire 610) and I seem to have the opposite issue as others who have similar problems. Everything starts up fine, and I can record audio into Ardour using my inputs, but I can't get any output from any of my 8 line outs.
I've checked the connections using QjackCtl, and I tried to route audio from another program (Audacious) but I can't seem to pull audio out of the device (or the computer won't send my device audio?).

I have updated my Ubuntu to Lucid 10.04 from 9.10.
Although my sound disappeared in 9.10 only, I thought maybe upgrading might help, but there is no change.
I guess everything is installed fine.
But still aplay -l command shows "NO sound cards.. "
Moreover the sound preferences shows no hardware, no input and a dummy stereo output.
I have banged my head a lot trying various things written in forums and all but no success.
One more thing : When I test "osstest" , I get sound in both the earphones , but altogether there is no sound. I am very much confused.

I finally got audio working on my ubuntu 9.10 desktop... now I am having sound issues watching movies from a network share.The sound device continually randomly changes to "dummy output device" and then there is no sound output. The sound icon dissapears on the toolbar. To get it back and audio to start working I have to $sudo alsa force-reloadIt seems to happen everytime there is a network delay, the movie will stop for a second and then when it plays the sound is gone

I have a fresh install of Natty and i'm having some issues getting sound to work. My laptop has a built in sound card which works just fine. However, i also have a usb 5.1 sound card which isn't working at all. Both devices show up in 'Sound Preferences' but when i select the 5.1 device as the output device sound doesnt work. I ran the alsa-info.sh script and the output can be found here.

Running 10.10 and win 7 on my HP dv6-2150us laptop and I'm having a few issues.
First how do I get HDMI audio output to my TV? I think I have just a integrated Intel graphics card. It works fine in windows but I can't seem to get it to work in Ubuntu. I tried searching but couldn't find anything pertaining to this issue.

Is there any way to select which output device a program uses? I notice many Ubuntu programs lack the choice to choose where the sound is outputted, for example Rhythmbox and Exaile.I have 3 sound outputs (Internal, PCI, HDMI) connected and I'd like to for example use the PCI card as default audio device but play music from Rhythmbox through the internal motherboard output.

After a lot of messing around and research, I figured out how to actually get my bluetooth headphones to connect and stay connected. Although once I shut them off, remove the device and re-add it using Blueman.
Right now, `pavucontrol` shows "Headphones (unplugged)" and there is no sound coming out of the speakers. But there is no sound coming out of the headphones either. They are set to the fallback. I've opened `alsamixer` and made sure everything was turned up. Still, no sound.
Since `bt-audio` isn't on Jessie, I don't know what I should do. It seems like this may be the missing step but I am unsure.

I use ubuntu lucid x86_64 with pulseaudio. There seems to be some issues with how the audio is sent to the sockets. When playing an MKV with surround sound "front" recieves none of the actors voices. it almost sounds like it is the rear sound. Centre/subwoofer sound works correctly. I also get a problem with headphones and front where I cannot mute front and allow only headphones instead I can just mute headphone socket. This is entirely confusing so I hope someone can help me in the right direction.
Hardware: Nvidia 7600 gfx P5QL-EM mobo with 8 channel surround sound audio and hdaudio/ac97 cable which is set to hdaudio on mine in both bios and physically connected cable.

When I connect my Treo 650 with a USB cable it works sometimes and not others. A little investigation showed
that it always works when I see the Palm device listed in the output of lsusb. While trying to diagnose why it appears sometimes and not others, I discovered that it sometimes appears in /proc/bus/usb/devices and not
in lsusb. I didn't think that was possible!
I've tried running kudzu (the Red Hat hardware discovery tool) and killing and restarting udevd.

I finally decided to transition to a 64-bit install (AMD64). (same machine, just reinstalling as a 64-bit kernel starting w/ a Debian squeeze netinstall image) My audio chipset is nvidia MCP61, and it was working perfectly under a 32-bit kernel (I did the transition because a poorly-written system backup script (my fault) hosed /usr, /bin, and /sbin) When everything was up and running:
*: KDE4 only recognized the output device as ALC1200 Analog
*: kmix only had a single channel(master)
*: alsamixergui did recognize all the channels
*: some games (sauerbraten, for example) had no sound in KDE4.
*: some games (warzone2100, for example) did have sound in KDE4.
*: the games that had no sound in KDE4 did have sound in fluxbox.
I removed the following packages (some of which I had installed to try to get audio working properly):

I'm still trying to find out if my coby mp3 player will actually play mtv video files as is advertised.
ffmpeg -formats does list mtv but the only command I really ever used was one to convert a vid to an mp3 so I tried Code: ffmpeg -i test.mp4 -acodec copy output.mtv it returns Code: Unable to find a suitable output format for 'output.mtv' I can't find any mtv files online for purchase or free for that matter, so I know this is all pretty obscure but shouldn't there be a way to convert them since ffmpeg lists mtv format?

I've been having a recurring problem on Slackware64 13.1. If I open VLC (or any other media player available for Slackware) before I open Firefox, then my sound works 100% and there's never any problem, however, if I open Firefox first, and there happens to be a flash video loading, then any other media player (mplayer-plugin, Amarok or VLC) will fail to play sound. VLC tells me:
Quote: Potential ALSA version problem: VLC failed to initialize your sound output device (if any). update alsa-lib to version 1.0.24 or higher to try to fix this issue. Now, I'm happy to do that if it will actually fix the problem, though I'll have to figure out how seeing as I'm something of a n00b. The thing is that I've not really done anything to alsa except run alsaconf on my first boot, so I'm not sure if that's really the problem I've been using Slackware64 for a few months now, I'm on my first ever install and for the most part I'm loving it. Been working through the little things that have been annoying me, and for the most part I've managed to find solutions either by reading the Slackbook, by browsing LQ or by doing a quick Google search. However, I can't seem to find any reference to this specific problem anywhere and I'm not sure what I should do.

I just upgraded from Ubuntu 9.04 to 9.10 today, and went to watch a movie on my hard drive. I typically do this with an S-Video cord on my TV. In Ubuntu 9.04 I did so simply by plugging in the S-Video cord, then pressing FN+F4 on my keyboard. Worked like a charm.
After the upgrade the same key combination just changes my resolution setting.

According to 'man luvcview', if I do this:
Code:
luvcview -o testvid.avi
then luvcview should capture the video to the .avi file. However, when I try it, no output file is created. Grabbing a raw stream or raw frames works fine, but not the creation of AVI files. Am I missing something?

I work at a television station and we recently purchased a System76 Meerkat ION with the intended purpose of using the HDMI out port for broadcast purposes. We have an existing AJA HA5 box which is capable of converting HDMI to HD-SDI (HD-SDI being the baseband standard in professional broadcasting).
The converter is only willing to accept the following values:
1920 x 1080 @ 29.97
1280 x 720 @ 59.94
I am wondering if it is possible to manually configure Xorg.conf (or whatever file is being edited by NVIDIA X Server Settings) to tell the HDMI output to only produce the latter resolution (1280 x 720).

On an Asrock ION 330HT-BD box Im running Ubuntu 9.10 (2.6.31-17-generic) with the nVidia driver 185.18.36. The Asrock box uses the nVidia ION chip and the nVidia driver appears to be working without any problems.
My problem is, that I what to use the box as a MythTV frontend with an (old) SD Plasma screen as display, which have a native resolution of 852 x 480 and I cant get the box to output a 852 x 480 signal. The Plasma is connected with a HDMI -> DVI cable. No matter what settings I have tried in the /etc/X11/xorg.conf file, the box keeps outputting a 1024 x 768 (or higher) signal
Questions:
1) Is the nVidia ION chip capable of outputting a 852 x 480 signal?
2) If Yes to above, how do I configure my xorg.conf file?
