I've tested again the demo 4musiK (Dune ;) with the latest version of the sources.

The music starts with a clear expected sound.

After ~10 seconds, the quality starts to  decrease and it becomes noisy and glitchy.

After a few more seconds, the sound starts again to become clear and good.

And it repeats like this in loops.

My demo uses the DSP as the sound source for the crossbar.

The other demos I listed, where the bug is still apparent, do not need or use DSP (I'm using "--dsp none").

Something to dig here maybe ?

I'll continue to check some demos tonight.

I found some code from a few years back;

I'm a noob about setting up the Falcon sound system but it does play 16 bit stereo 49170 Hz OK on my Falcon in 030 and 060 modes.
In Hatari it will get distorted sound that comes and goes.


thanks, that's just what I needed, it will be easier to fix/improve falcon sound with a "simple" program that just play sound and wait for a key.

One bug was fixed, related to the new CycInt code ; sound is now better, at least during 20 sec when using your falcsmp.tos test.

After that, it becomes noisy again, some bugs remain to be fixed :)

I can confirm that in the beginning the sound seems now OK.

In case of the "Brainstorm: Mouse" demo, sound loop is so short that one does not hear the issue any more.

In the other problematic demos one can still hear the issue after a while.  In Django "Red Drops" song probably soonest.
