My DSP programming is pretty much nonexistent, but it does looks as though this chip might be up to Vorbis decoding? OK so I wouldn't expect some individual to rush out and build a player based on this chip, but once hardware becomes available that uses this chip, it might become easier to 'modify' the firmware to add Vorbis, no?

Cirrus's page on the chip:
http://www.cirrus.com/design/products/overview/detail.cfm?d=912

Chip specs:
http://www.cirrus.com/pubs/cs7410-1.pdf?DocumentID=894

Page says "Supports MP3, WMA, and other audio decompression standards 
upon request" -- anyone want to request?

This looks like all the hardware guts of a CD player, except of course 
the actual CD reading part, on one chip, plus DSP to do compressed audio.
