Public bug reported:
I've just upgraded one of my machines to Ubuntu 8.04 and something
seems to be wrong with the sound. Needless to say it was working fine
before, but now I get sound, but I'm unable to control it, i.e. I'm
unable to raise/lower or mute it. I.e. if I open volume control and
try to lower the volume bars they just jump back up to the top. This
is fairly important for this machine because it also acts as a mythtv
frontend.
The output of "alsamixer":
alsamixer: function snd_mixer_load failed: No such file or directory
and "lsmod |grep snd":
~$ lsmod |grep snd
snd_hda_intel 344728 0

And "$ lspci |grep Audio" is:
00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio
(rev a2)
and output of "$ aplay -l" is:
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC861 Analog [ALC861 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
Just in case any of that helps.
Any suggestions appreciated!
