Hi,

I wrote an aidio driver for dreamcast, and I post it to netbsd-bugs.

  http://mail-index.NetBSD.org/netbsd-bugs/2003/08/19/0008.html 

* AICA has 64 PCM channels. but this driver support only 2 channels
  as left and right.
* 4bit ADPCM, Signed Linear 8 and 16bit PCM supported
  (Other encodings are emulated)


Unfortunately there's not enough speed to decode mp3.
Will somebody please optimize mpg123 for SH4? :-)


enjoy
