Bug Description
Binary package hint: pulseaudio
When pulseaudio is running, it forces my "PCM" volume (as seen in "alsamixer") to 100%.
This is not acceptable, since my (laptop) speakers sound terrible unless the PCM volume is turned down.
I tried following the instructions in bug 410446 to stop pulseaudio, reset my mixer settings (also tried "alsactl store 0" to save them), and restart pulseaudio. But the PCM volume always goes back to 100% as soon as pulseaudio restarts.
I have used several Ubuntu releases before Karmic, and none have had this problem.

I can't reproduce this symptom using the same HDA codec and revision.
Also, please try the ~ubuntu-audio-dev PPA.
