Public bug reported:
Using an updated gutsy. I had just gotten my hda-intel sound to work,
then I got some synaptic upgrades which I installed and then it said I
needed to reboot. Once I had rebooted the machine my sound didn't work
anymore. I noticed that in this last synaptic upgrade I got a new kernel
(the new one was 2.6.22-12-generic).
In gnome volume control under "file::change device" I used to see two
devices (they were "HDA Intel" and "RealTek ALC268"). I had "HDA Intel"
selected when the sound worked. After the upgrade+reboot I only see one
alternative in this menu and it says "Realtek ID 268" (not quite the
same as before, small difference there).
Also, before I could launch "alsamixer" but now it just says "alsamixer:
function snd_ctl_open failed for default: No such device" and fails to
start.
I have seen some really weird messages in "dmesg" which I think is
related to this (see bottom of the attached file).
