Many demos suffers sound speed, glitches or unsynchro between sound and effects.

It seems that the effects run too fast, or the Falcon DMA sound too slow, I don't know.

the demos are often using dsp to play the music (mp2  decoder for example), which makes it harder to isolate the problem.

does someone know a demo (or a program) for falcon that just plays DMA sample using ff8903/05/07 (similar to the STE's DMA sound).

Demos listed in the compatibility list that are marked to:
* Use sound
* Not require DSP to function
* Music being there only if DSP is enabled

Are good candidates for that. I can go through them today with DSP disabled, to check whether any of them has bad audio.

As none of them is supposed to have problems, it's a good regression check in any case.


I would need to check DMA play mode->DAC first before checking DSP->DAC

Or if someone already has a simple asm code to init crossbar + play a small sample with dma , that would be handy too and would save me time instead of doing it myself :)

Laurent?
