Hmm... I remember a while back (2.0.3x series) when I had a PAS16, I had problems
with the right/left output getting reversed. I've since moved to a SB16, but I'm
fond of the PAS (better mixer controls etc) - I was thinking of dropping it into
one of my other systems. Could someone check this out and see if it's still a
problem, or if I just have a buggy hardware?
