There is a hardware volume knob which should take care of that. Anyway ... I will try to fiddle with that channel map ... it did not occur to me before, but maybe that setting could be wrong?

I have always used pulseaudio -k for disabling it entirely, but this might be useful. You have asked whether this DAC works well in some other OS without some special drivers. The answer is, to the best of my knowledge, no. I have only tried that DAC on friend's laptop with Windows Vista and it did not work (same issue - silence). And since there are no special drivers (the website states that it should work out of the box on Windows and Mac OS X... ) we have given up trying. So, I suppose that if channel map settings do not change anything, I will end up debugging the usb communication.
