I'm not sure, if it's possible in a simple way. The extra voice is
required to do the proper interrupt acknowledge. If I remember correctly,
the interrupts are going faster than voice position otherwise.

Anyway, it wouldn't be a big problem to update driver and create a new 
(ONE!) PCM device with multiple mixed channels (up to 63).
