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've run all of them that did not have clear sound with Hatari Git,
also with Hatari v2.3.1.
(I tested them with EmuTOS v1.1.1 512k version as that's supported by
both Hatari versions, and boots *much* faster than TOS v4.)
As audio in all of these has regressed, issue is not DSP related:
* An cool: The Keff demo
* Brainstorm: Mouse
* ICE: Tron2001 [1]
* Opium: Falcon Flight
* Rabenauge: Chipo Django 1 [2]
* The Respectables: Cebit 93 demo
* Trio: 124 beers later
[1] This has regressed also otherwise. It shows just the intro stuff
at beginning, but exit when its tron2001 game demo should start. It's
not recent regression though as same issue is there with v2.3.1.
[2] This works both on STE & Falcon, so if you want to compare those
too, it might be good to test against 16Mhz 030 STE. IMHO you hear
issue best at start of "Red Drops" song (press "3" for it).
If these had audio issues, diff was not clear enough for me to hear:
* DHS: 4orce (4K)
* Impulse: Bugs from Outer Space [3]
* New Beat: Flu (4K)
Anders, as I assume you to be familiar with "4orce", maybe you could
check it better? :-)
[3] I thought it had sound also in rest of the demo, not just start,
but that's same with v2.3.1. Maybe it has same issue as Opium's
"Chrome Dragon", which has been missing music completely since v1.8?
