[Pkg-alsa-devel] Bug#615225: alsa-base: NVidia CK804 with ALC850 goes missing during wheezy upgrade

Package: alsa-base
Version: 1.0.23+dfsg-2
Severity: normal

My system was working fine with Squeeze, all the way through to the final
release.  Sound works fine using the "NVidia CK804 with ALC850" integrated in
my motherboard.

As soon as I upgraded to the wheezy testing release, however, the sound
stopped working.  KDE reported that "NVidia CK804 with ALC850" had been
removed. It did, however, find "HDA ATI HDMI" which seems to be the HDMI port
on my video card -- I believe that was also present under Squeeze but I can't
be certain.

The fix turned out to be to set "probe_mask=1" for snd-hda-intel in
/etc/modprobe.d/alsa-base.conf.  That then causes both the ALC850 and the HDMI
port to be found.

This seems to be some sort of regression in wheezy as I did not need to specify
that in squeeze.
