Well, if you have Deneb and CSPPC in your A4000 you can connect cheap USB sound card to Deneb and do the mp3 decoding via PPC CPU. :smile:

MPEG device for Delfina DSP.
Device's DSP decoder core has been taken from DelfMPEG. Delfinampeg
device implements a standard mpeg.device interface, which can be used
with player programs, like AMPlifier, Frogger, and AmigaAMP (through the
MHI driver).
I have read somewhere else that this combination does work. During the Deneb installation procedure, somethings pop up about what clockport should be emulated according to the hardware you want to use with it.
