I solved the problem for me with the Links from Daniel T. Chen
It's the "volume=" statement in the "analog-output*" files /usr/share/pulseaudio/alsa-mixer/paths/.
Now the only problem i still have is that some combinations of master and pcm volume generates a high frequency noise, but this seem to be a problem of the alsa driver for my xfi soundcard.
