On macppc, the audio driver is at major 48, not 42...

Not that I know of... but hopefully, the MAKEDEV script has the correct
info in it. (cd /dev; sh MAKEDEV audio) should do the right thing... The
macppc MAKEDEV says:

audio*) 
        unit=${i#audio}
        audio=audio$unit
        sound=sound$unit
        mixer=mixer$unit
        major=48
[ ... ]

You could also look at the devsw table in sys/arch/macppc/macppc/conf.c:
        cdev_audio_init(NAUDIO,audio),        /* 48: generic audio I/O */

(42 is the USB generic driver, ugen, BTW).
