As the co-author of that driver, it pains me that it's broken. 
Unfortunately,
my only maestro3 hardware was in a laptop that no longer works.  If anyone
has the hardware as a PCI add-in board and is willing to loan it to me, I'd
be very grateful.

Another thing to try would be to edit the driver source and reduce it's play
channels to 1 by changing M3_PCHANS.  This wouldn't fix the problem, but
in the past the driver has been very fragile with multiple channels enabled.
