Public bug reported: Hello,
I am not sure if the is a alsa-driver problem, or a pulseaudio problem. I have had problems with my on-board sound a few times in the past, but up until today I always found a solution on the net. The problem started like the times before: I used the computer, turned it off, and when I turned on the PC the next time, there was no sound. No drumbeat on the login page, and no sound coming from any application. I tried playing around with the Sound Settings, PulseAudio Volume Control, as well as the alsamixer via terminal. No luck. I removed and re-installed alsa-base and pulseaudio a couple of times, I also upgraded alsa to the latest version, no luck. I tried going back 1 kernel version, still no sound. I removed the latest kernel (3.2.0.58) and tried removing and re- installing alsa and pulse audio using kernel version 3.2.0.57 , still no sound. Then I installed the latest 3.8 kernel version, and this time something changed. I now can activate the microphone via alsamixer in terminal, and I can hear it on the speakers and the headset, but still no sound coming from any application, also the speaker test in the Sound Settings had no sound. Clueless at this stage. One thing I'd like to mention... the first time the sound stopped working, I read that Ubuntu had issues with that chip (892), so I bought a Soundblaster 5.1vx pci card, which worked fine after I followed this tip (http://www.webdesignblog.asia/operating-systems/linux- os/soundblaster-5-1vx-activate-all-speaker-channels-ubuntu-12-04/), then one day it just disappeared. I mean it is still plugged in, but Ubuntu couldn't find it anymore. To my surprise the onboard sound was working, I guess it was fixed during an update, so I just started using the onboard sound. The Soundblaster is still plugged in now, but even during all the troubleshooting I did the past hours. it was never recognized by the system...
