Well the sound player I wrote works more like MP2 decoder: streams data
in over SSI and plays back over SSI. 030 is not really involved and
there are no synchronisation points in the code. Once DMA is started on
030 side it should tick along nicely.
The other thing is that I was never able to get MP2 playback work in any
demo with hatari. Could this be down to my laptop being to slow? (it's
i7-3820QM).
Could be ; as a comparison, do you get correct sound with the demo '030'
by DML ? In all the parts, even those using the DSP ?
When DSP is enabled and run some program, performance will get impacted
due to the high number of instructions per second to emulate.
In Hatari's UI for CPU settings, you can try to untick "prefetch" mode
and "cycle exact" mode, this should use less ressources.
