 Going to test on a couple of other systems before I close the ticket but
 my initial attempt with the latest daily build of HEAD shows the issue
 as resolved on a 14" iBook G4.

 My test was 'audioplay my.wav'

 obio0 at pci1 dev 23 function 0: addr 0x80000000
 snapper0 at obio0 offset 0x0: irq 30,1,2
 snapper0: codec: TAS3004
 audio0 at snapper0: full duplex, playback, capture, mmap
