A final update, just in case anyone else is bothered by the same weird sound issues on their systems that plagued me: I could solve all problems I described here by ultimately going back to Steem SSE 4.0.2. The sound is completely ok for me in that version and is (tested) the same performance as Hatari on my system. Even the minor issues I still had with 3.9.3 are gone. Also, the thing I mentioned about configuration files in the end is also working in 4.0.2. I can create batch files and shortcuts...

Ok, had no luck with those settings. Vsync settings (Auto Vsync on/off, Vsync on/off in all combinations) didn't change anything, increasing hard loop didn't change anything, and checking microseconds seemed to make it worse. But possibly running those programs without HDMI connection only on Laptop may have made it better. It's hard to say, because the Laptop speaker is not really giving any good clear sound anyway. Maybe something with my hardware and setup that's hard to pinpoint may be the root...

Oh, you're right. I stopped Emulation and could check "Emulation Thread" box finally. And now I actually hear differences - the filter changes the sound from high to low pitched, old filter settings have a somewhat different sound etc. Dumb noob problem lol. Unfortunately, the pops / clicks are still there, also with changed filters and the other settings. Old Filter and new filter settings or unchecking the other source options don't have an effect on the crackling. But I will check hard loop timing...

Ok, thank you very much ! Will try these settings tomorrow. Just one question: I got a Laptop attached to a Full HD TV Screen via HDMI. Could that have anything to do with a problem like this? But that setup doesn't give me any sound problems with other programs and emulators and, as I wrote, also doesn't occur that much with 3.9.3.

I had a look at the options you named and noticed: I apparently can't even change YM-2149 and digital sound, if I uncheck, I noticed now it's checked again if I start the program anew. I can change Low-Level, though. but the changes don't change anything about the sound. I checked high pritority, but it doesn't change anything. It was already at 16-bit / 44.1 khz. Changing to 48 khz didn't change anything. Run Speed was already at 100%. Emulation Thread is greyed out for some reason. I can't check...

Oh, I forgot: Low-Level /YM-2149 makes no difference, also going into the older filter version or turning the newer to the left side of that filter control doesn't make any difference either. Also machine and TOS options from St to Ste to Mega St to Mega STE with the recommended UK TOS version in your manual didn't do anything as well.

Thanks a lot for your reply! Attached here is trace.txt from the current version that has crackling sound in a more intense way (I'm not sure if it helps if I also post the 3.9.3 trace.txt, of course I can do that, too.) I will check modifying the options you named a little later tonight and post if there was any difference. One good example I can name right now of software that shows the versions' sound performance differ quite much is a game "Skull Diggery". It has clicks in the title melody sequence...
