Is it possible to limit maximum volume in PulseAudio? Currently, PulseAudio sets PCM channel too loud which results in distorted sound. I use aumix to turn volume down, but whenever any other sound is played (IM notification etc), PA plays with knobs, turning master volume down and PCM up.

aumix  ++++++++++++++++++++O+++++<Vol      
       ++++++++++++++++++++O+++++ Pcm            ++++++++++++O+++++++++++++

becomes:

aumix  ++++++++++++++++O+++++++++<Vol  
       ++++++++++++++++++++++++O+ Pcm            ++++++++++++O+++++++++++++

I use OpenSUSE 11.2, pulseaudio 0.9.21, ALSA 1.0.21 and ALC889A sound codec.
