bob,
The switch of the NAD to front:CARD=Audio,DEV=0[ALSA]NAD USB Audio,Front Speakers
worked to get the NAD to play. I haven't tried all 13 NAD choices on the list... I think this was my 4th try. Is there some ranking to get this right? I have at least 1 3CD set of 24bit files. I don't remember the data rate. I'll check that out.
