Ubuntu PulseAudio Problems
PulseAudio depends on ALSA
Well, after months of successful Hardy, my audio just died! Silence!
Panic stricken, I booted into XP and sighed in relief as the all-too-familiar-and-hated windows sound came from my 2 year old Dell 6400 laptop.
Ok, so confirmed it was not hardware related, I booted back to Ubuntu 8.04 and the silence. Time to Google!!
I found various interesting things including the paprefs and pavucontrol packages for configuring and diagnosing specific problems, but the final solution came from PulseAudio themselves: Check the alsamixer levels! Ok!
So I found the PCM levels in the ALSAMixer at 0, raised them and we're done!
