In Setup menu, set:
- Sound: STE stereo
- Music: STE stereo
-> Music you hear is almost pure noise.
I don't really remember what was the issue, maybe something about the DMA
play length being zero?

I'm nore sure.

Any idea to which version of Hatari?

OK. Any idea when did it start to work / what's the earliest version of
Hatari in which you remember it working fine?
I wonder was this something similar to issue Pure debugger apparently had
with the Gemdos emulation which was fixed for v1.4?

Me neither. I tested quickly Neochrome master in some earlier Hatari
version and didn't see anything, but without knowing what was the initial
issue, it's hard to say anything about it.
-> Maybe set the version to v1.3 where you did lot of video fixes...

Does the list have any (former) Protracker STE users who could check this?

Ok, in that case this probably needs to be mentioned in the release notes
and compatibility list needs to state something about it too.
 e.g. "Some DSP-timing sensitive Falcon demos that by luck happened to
work with Hatari v1.4, don't work anymore in v1.5 with the default AUE
CPU core. This is because while DSP cycle accuracy has been improved,
the default UAE CPU core isn't fully cycle accurate. The experimental
WinAUE core is needed to run them, please see Hatari README for more
information on that."
 e.g. "More DSP-timing critical demos, like the ones using DSP
MP2-player, work only with the experimental WinAUE core. Please see
Hatari README for more information on that.
README could also state that we hope to have the WinAUE core as default
in next Hatari release, but old AUE could still be (configured and) used if
speed is an issue.
