5.1-channel USB sound device on 8.0-RELEASE

[MIHIRA Sanpei Yoshiro]

Hi.

  I tested below device on 8.0-RELEASE with patch.

>*1 Kyo-On DIGI(sorry,this page was writtin in Japanese)
>http://www.area-powers.jp/product/usb_product/product/kyo-on/u1soundt4.html

  This device is 5.1-channel USB sound device.

  Without patch, ``No playback!''
ugen0.6: <vendor 0x0d8c> at usbus0
uaudio1: <vendor 0x0d8c product 0x0006, class 0/0, rev 1.10/0.10, addr 6> on usbus0
uaudio1: No playback!
uaudio1: Record: 48000 Hz, 2 ch, 16-bit S-LE PCM format
uaudio1: No midi sequencer
pcm1: <USB audio> on uaudio1

  With patch:
uaudio1: <vendor 0x0d8c product 0x0006, class 0/0, rev 1.10/0.10, addr 6> on usb
us0
uaudio1: Play: 48000 Hz, 8 ch, 16-bit S-LE PCM format
uaudio1: Record: 48000 Hz, 2 ch, 16-bit S-LE PCM format
uaudio1: No midi sequencer
pcm1: <USB audio> on uaudio1

  But I could not play with mpg123, only noise.
  How can I use this device on 8.0-RELEASE.

Cheers.
