Sorry, Konstantin,
I didn't. At this moment, I'm at my office's system and don't have 
access to my private box, I'll check this in the evening and report.

Best wishes,
Oliver

P.S. Just a stupid question: are the DACs of the M-Audio Revo 5.1 
capable of beeing initiated by an entry level of volume (or current in 
this aspect)? Maybe such a default level is choosen too low?
