No sound after upgrade to 10.4

[ChiefSmash]

Hello everyone-
I am relatively new to the world of Ubuntu and I know others have had very similar problems but I have yet to find a solution. I recently upgraded to 10.4 and lost my sound. I tried installing and uninstalling PulseAudio and various ALSA utilities but I have not been able to resolve my issue. Strangely, when I try to play an mp3 in an application like VLC and then open up the PulseAudio volume control, I can see a playback bar as if an audio signal is going out. I am not, however, able to hear any sound via internal speaker, analog headphones, usb headset, etc.

I ran aplay -l and got the following result:

aplay -l

I also ran an lspci -v and got:

Any tips or help would be greatly appreciated.

Thanks in advance

Use the alsa-info-script to provide detailed information.
Run this command in a terminal:

wget http://www.alsa-project.org/alsa-info.sh -O alsa-info.sh && bash alsa-info.sh

Enter your user password when prompted. Choose the upload option and provide a link for the output.

Cool...I got it! Thanks a lot

Ok thanks again for the help! Here's a link to the output of alsa-info.sh:

You might try upgrading your alsa install using the link in my sig. First uninstall alsa-backports and make sure you have installed build essential:

sudo aptitude install build-essential

Also, what is the output of this command:

sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*

[ChiefSmash]

Ok I uninstalled the backports and ran the upgrade download/compile/install script from your sig. I also ran the build-essential install. Everything seemed to go well.

The output of the command you mentioned is:

sudo fuser -v /dev/dsp* /dev/snd/* /dev/seq*
                     USER        PID ACCESS COMMAND
/dev/snd/controlC0:  myusername    2470 F.... pulseaudio
/dev/snd/pcmC0D0p:   myusername    2651 F...m chrome
/dev/snd/timer:      myusername    2651 f.... chrome

So I guess PulseAudio is not gone afterall.

The last kernel update broke my sound. I had to go back to 2.6.32-23.

lspci -v

A little similarity there. I don't mean to high-jack, just suggesting that you might be able to go back to an earlier kernel.

EDIT; solved my problem thanks to this post http://ubuntuforums.org/showthread.php?t=1557572
For some reason my user wasn't part of the audio group, witch doesn't seem to matter with the earlier kernel.

Try removing your old config files.
Using a Terminal="Applications->Accessories->Terminal"

rm -r ~/.pulse ~/.asound* ~/.pulse-cookie 
sudo rm /etc/asound.conf

Logout/in.
Ignore any not found errors.

Ok I just decided to re-test with my headphones plugged into the front jack and, voila, I have sound! So somewhere along the way my audio started working again through the front headphone port and rear speaker port. I just need to get it coming through my internal speaker again and I'm all set. Thanks everyone for the help!

Is this a laptop? I thought it was a desktop, in which case no internal speakers.
