Re: [gentoo-amd64] sudden sound loss

[Raffaele BELARDI <raffaele.belardi@st.com>]

I had the same problem on an NVIDIA 430, alsamixer levels ok, sound
unmuted, no syslog errors, after boot sound was ok but when I tried to
change the volume it muted and I had to reboot to get it back. It turned
out that the default card model for the alsa driver had changed to one
not compatible with mine (6 jacks vs 3 jacks). I added one option on the
kernel command line ('snd-had-intel model=3stack', default is 6stack)
and now it is again ok.

I doubt it applies to your case, but better than nothing... You might
try to check
the /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt for
any changes that apply to your driver.
