Public bug reported:
When changing the volume Up and Down in Ubuntu 11.10 oneiric, the audio volume
does not change at all.
If you, for example use KWin (or alsamixer) to lower the "Master volume" from
100% to 0%, the volume does not decrease at all, until it reaches 0%. There it
is muted. Alsamixer, Kwin, volume button, they all make the same behaviour. It
is probably a gstreamer problem, or parameter for the kernel module
snd-hda-intel.
If you change the volume of the PCM output sound in alsamixer, it works,
reflecting the actual value. But master volume doesn't.
