I also noticed the described behavior since upgrading to 11.10. I have searched high and low and found this bug - and also https://help.ubuntu.com/community/HdaIntelSoundHowto in which I found that adding a line to /etc/modprobe.d/alsa-base.conf options snd-hda-intel model=eeepc-p701 made the volume controls work well on my eee-machine. Perhaps you can also work around the issue by setting the model parameter manually...

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.
