-----------------------------------
after some further tests, it looks like the stuttering only happens "live".
I tried to video record the problem (using Hataris built-in recording),
and to my surprise there was no stuttering in the recorded video. I used
the MP2 example for testing.
So Hatari seems to be rendering the sound correct but somewhere in the
audio output it goes a bit bananas.
-----------------------------------
I.e. those issues seem related to host performance and/or SDL2 audio
processing rather than to Falcon emulation?
It's definitely not host performance. I tried running our Falcon030 demo "It's that time of the year" on my computer at work (i9-13900@5.8GHz/Windows) and I get the audio stuttering described by Anders in its original post.
