 FWIW, on four real sparc machines I get:
 
 Sparc Station 20:

 The latter ist not very informative, ktrace says:
 
   2038   2038 t_ossaudio CALL  ioctl(3,AUDIO_SETINFO,0xe7fff188)

   2038   2038 t_ossaudio RET   ioctl -1 errno 22 Invalid argument
 
 
 The hardware is:
 
 audiocs0 at ebus0 bar 14 offset 0x200000 line 3: CS4231A
 audio0 at audiocs0: playback, capture, full duplex
 audio0: slinear_be:16 -> slinear_le:16 2ch 48000Hz, blk 7680 bytes (40ms) for playback
 audio0: slinear_be:16 <- slinear_le:16 2ch 48000Hz, blk 7680 bytes (40ms) for recording
 
 
 So I would claim this is a QEMU bug.
