Ubuntu Feisty - Sound was working, but mysteriously stops working after reboot.
Hi there...I'm running Ubuntu Feisty. I installed a fresh copy of Feisty a few months ago. When I installed, the sound worked great. "All of a sudden" the sound stopped working. The GNOME volume control shows a little "crossout" sign (like what's in front of a butt for a no smoking sign...you know) and you can't access the volume control. So I used this guide to try and diagnose the problem:
swoods@newcomb:~$ aplay -l
aplay: device_list:222: no soundcards found...
swoods@newcomb:~$ lspci -v
[NOTE: various devices omitted here...]

I haven't recompiled ALSA because I figure it works already as packaged with Ubuntu.
I got fed up and tried reinstalling, but to no avail. It worked well for awhile, but then I rebooted and the sound didn't work. Maybe there's an error log somewhere? I tried looking in syslog, but...nothing....
Look in dmesg (that is under /var). Have you tried running the command
alsaconf
from a terminal? I don't know whether this is still available on Ubuntu but it works well enough on Debian. You may need to install alsa-utils first.
Yep. LiveCD and initial Ubuntu install work fine. I tried thinking of all the changes I made between when it was working and when it didn't work, but I don't think I made any, really...I just rebooted. Perhaps something "took effect" on reboot.
Either way we should be able to diagnose it somehow.
I had this exact problem, and had also tried all the steps you mentioned. In my case, it turned out to be a permissions issue. For some reason, my user account wasn't in the "audio" group, so I didn't have the correct permissions to (I think) /dev/dsp.
I was having essentially the same problem as Woodsy934, except mine came after I created other accounts. The parent account worked fine, but no sound on the child accounts. I ran across a suggestion to restart alsa-utils (sudo /etc/init.d/alsa-utils restart) and chmod the permissions to the sound directory(sudo chmod 666 /etc/snd/*). These worked fine, until I rebooted, then I would be back to the no sound icon on the volume control. I strongly suspected I had a permissions issue but had no idea how to resolve that issue on a permanent basis. Tim J's message gave me that answer, and now all the accounts now have sound.
Thanks Tim J!
I know this is an old thread but I was having intermittent sound problems on my HP EliteBook 8540p running Ubunutu 10.04 and Tim's solution of adding my account to the audio group in /etc/group seems to have fixed it.
