I recently purchased an ISP-16 sound card from MediaMagic Inc. 
This card claims SoundBlaster Pro compatibility, and comes with
some nice Windows bundled software.

Anyway, after struggling to get things configured in my kernel,
wondering why the sound wasn't working - I think I hit on the issue.

If I run (under DOS) the MediaMagic supplied initialition program
(ISPINIT.EXE), then boot FreeBSD; things appear to work.  The probe
(usually) finds a SoundBlaster Pro.

If, however, I turn off the machine; turn it back on and boot FreeBSD,
the probe finds a SoundBlaster 2.1; and nothing works.  (cat'ing
a .au file to /dev/audio simply sits there until I hit cntrl-c.)

So, I'm guessing there's something in the probe which should initialize
the card before determining exactly what it is...   

Does anyone have any ideas?
