[ubuntu-za] Post intrepid 'no sound' problem - ALSA, PulseAudio, & drivers

[Hannes Coetzee]

Hi Péter

I've noticed on some of my boxes that the GUI apps for ALSA does not 
always work properly. Run alsamixer from the terminal and see if 
anything is on mute. If all else fail you can always compile a driver 
for your card and it's really not that difficult. Just make sure you 
check what version of ALSA you have installed and download only the 
source for that version. Trying to compile later versions can be a 
nightmare. Everything you need to know can be found on the sound trouble 
shoot page you looked at.

Regards
Hannes
