This is because of the dead-simple (read: lame) playback loop
which can't keep up with the Ondio reading the MMC as well.
I now have a version which uses DMA for playback and does
buffering as well. Smooth playback on both recorder and Ondio.

I'll polish this a little more (possibility to stop, read
parameters from WAV file to play all 16bit PCM WAV files
correctly, restore the MAS so mp3 playback won't be broken
afterwards) then commit to cvs.
