I am seeing this same behavior with my SBPRO. I *know* that the SB is
being configured for irq10, (boot message) and the parallel port is
at irq7.  I have not said much about this as I am way too busy to look
into the problem.  My behavior is slightly different. cat'ing *.au >
/dev/audio hangs. Sending something to the printer on /dev/lpa0 will
cause it to flush bits of high speed sound to the audio.
