I wonder if you have some sort of codec conflict going on here. Try adding the
following line to /etc/modprobe.d/alsa-base, and rebooting.
options snd-hda-intel probe_mask=1
That will just select the first codec, which should be the one for your
soundcard, if there are more than one codec in the equation.
If that doesn't work, and the next time you get the sounds up and running,
post back the output of the following stuff.
cat /proc/asound/cards
cat /proc/asound/version
grep ^Codec /proc/asound/card?/codec*
If the probe_mask option does work, post back the output of the above stuff as
well, as it may be helpfull in getting a solution to the problem.
All the best.
Nigel.
