I've commited it (and will pullup -9 later).

In 8.99.39 audio(4) has been changed to attach with the number of maximum
channels that hardware supports.  But auvia(4) had following mismatch:
- auvia_round_blocksize returns 512 bytes (in most case).
- audio(4) layer requires that round_blocksize returns a multiple of
  framesize, (precision/8 * channels).
This is not a problem for 2ch/4ch, but is a problem for 6ch.

Thank you for reporting.
