I did found out that my sound card for WL500gP has some serrious issues with BASS. In mpd i have workaround this using software mixer and decreesing volume into 30%, and on hifi device setting the volume so i could hear.
As lastfm does not work for me in mpd ( maybe someone how why?) i have been using shell-fm 0.6 however i cannot set the volume there ( shift+, shift- does not work / * i complity shutdown volume).

So i got a question - Is it possible to set the mixer spectrum somehow on system level, or set the default volume which is used ?

Thanks in advance.
