Sound Card Detected, Supported, No Sound

**EdSquareCat** · 02-22-2009

My sound hasn't worked since I installed Ubuntu 7.04. I'm currently running Ubuntu 8.10. My on-board card (nVidia Ck804) is supported by ALSA. Here: http://www.alsa-project.org/db/?f=9c...ec7345557e3e4f is my alsa-info.sh results. Any suggestions?

When you go into the volume control, are the slider's up for both master and PCM, and are they both unmuted? Are you sure your headphones/speakers are plugged into correct port?

Under system->preferences->sound what is the defaul mixer set to? what is sound playback for each item set to? If they are set to autodetect, try setting to alsa, then press test button and see if you hear sound, also try the other options on the list as well

Yes, those sliders are up. My speakers are plugged in correctly; the sound works in Windows. The default mixer is set to NVidia CK804 (ALSA mixer) Surround. All sound playback settings are set to ALSA, although when I test it gives me this error for some settings:

Code:

audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! 
gconfaudiosink: Could not open audio device for playback.

And a similar error for others:

Code:

audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! 
gconfaudiosink: Could not open audio device for playback. Device is being 
used by another application.

And this error for PulseAudio:

Code:

audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! 
gconfaudiosink: Failed to connect: Connection terminated

I don't know that I am using sound in another application. The only thing opened right now is Firefox.

I am at a loss, did a little bit of googling, this is the first thing I found notable. Save this in a file, pulse.sh

Code:

#!/bin/bash
# fix for PulseAudio auto-start broken

sleep 8
killall -9 pulseaudio
sleep 5 pulseaudio&
sleep 5
paplay /usr/lib/openoffice/share/gallery/sounds/space.wav

Then execute it in a terminal, you will have to chmod +x the file first. See if that does anything. I google for

Code:

gconfaudiosink: Could not open audio device for playback.

I actually found the same file shortly after posting. Executing gives the error

Code:

sleep: invalid time interval `pulseaudio'
Try `sleep --help' for more information.

derrr, thats my fault for not seeing the problem with that script

Code:

#!/bin/bash
# fix for PulseAudio auto-start broken

sleep 8
killall -9 pulseaudio
sleep 5
pulseaudio &
sleep 5
paplay /usr/lib/openoffice/share/gallery/sounds/space.wav

try running it with sudo, see if that changes anything, i'm really at a loss, don't know what else to say, sorry

**EdSquareCat** · 02-24-2009

Using sudo gives the same error. Thanks for the help though! You aren't the first
