Audio went out for the on board device?
 
I'm running xubuntu 12.04 desktop and my audio was working just fine until recently. The issue seems to be with the onbaord audio card as my wireless USB headset works.

I know the module is installed and the system detects the hardware for my audio device. I've checked alsamixer to make sure nothing was muted as well as the pulseaudio.

Any ideas why the system just would stop working with the onboard audio?

Code:

$ sudo lspci -v |grep -A7 -i "audio"

the first thing I would try is to boot another os (windows or livecd) and test if it can use that device.
Also you can check bios settings and log files.

I checked just to be sure but I knew I didn't change my BIOS settings since it started.
Also I booted in to both windows7 and Slackware14 and the audio worked fine.

For some reason my user account was removed from the audio group. I've looked back in my history to see what might have caused this and the only ones I can tell would be apt-get commands. Its working now though, should have checked the groups first.

Thanks for the reply thought I was going crazy with all the things I checked and the results.
