Nice :)

Well, mp3 decoding is pretty CPU-intensive ( at least for machines of
this age ) - it's eating about 40% CPU time on my 110MHz microSPARC II.
And then - did you compile mpg123 with -mcpu=3Dv8 and so on?

Yeah, at 100% CPU load that's expectable :/

Hmm, this means the driver couldn't put the codec into control mode, but
that's only necessary to set parameters like sample format and -rate,
shouldn't happen during playback. I guess I should add some logic to
avoid unnecessary data/control mode transitions.

have fun
