Hi Roger.

I usually go for pulseaudio as the usual suspect, but it appears to be 
behaving itself on my Ubuntu Intrepid 8.10 install, on a machine using hda 
intel soundcard.

Have a go at opening alsamixer on Gnomes terminal, as user, as below. there 
was a problem where the PCM control was either being muted, or set back to 
zero when rebooting. I believe that was fixed with a kernel update, but you 
never know.

alsamixer -D hw:0

Perhaps you'd also post the output from the following commands.

cat /proc/asound/cards
grep ^Codec /proc/asound/card?/codec*
lsmod | grep snd

Don't give up. Most sound problems are resolvable.

Nigel.
