One thing confuses me, that the analogue device on the card is 0,0 and
the digital out is also 0,0 (per the asoundrc file). If this works for
other users, I guess this is correct, but it just seems odd (at least
to me). Also, are there any mixer controls that could be interfering
with the AC3 passthrough? I think only a current SB Live user could
answer these questions (my SB Live is still in my Win2K workstation.)
