Try to specify full port/irq/vector line here. In prefect case this must
not match sb0 values (like PAS does), or you need ALOW_CONFLICT_IRQ
or disable sb0

/dev/dsp1 will works if U have two cards, f.e. PAS & SB.

/dev/dsp{16} is very different from /dev/audio, /dev/dsp provide raw
access to soundcard DSP while /dev/audio do SUN-like ULAW convertion
additionly, mixing them does nothing good.
It looks like /dev/dsp is broken now, at least Ugen reports some
problems with tracker.
