Yes, I already saw problem like this : in fast forward mode, dma sound 
and cpu are not in sync sometimes. Dma sound doesn't seem too much 
"compatible" with fast-forward for now, I need to work on this (for 
example, in fast forward mode, dma sound is not sped up as is ym sound, 
which is not correct).

This is part of some fine tuning I need to finish on dma sound.
