What do you mean exactly? I've just used default settings. I'm reporting the bug in that situation. I suppose the development team can use that info to try to locate the issue.

I just tried GTK3VICE-3.10-win64-r46176.7z with the exact same sequence as I described above, here I CAN hear the digi music after the undump. This confirms the bug is real and is present in GTK3VICE-3.10-win64.zip, but not in GTK3VICE-3.10-win64-r46176.7z

Right. I start with a fresh Vice 3.10 release version, default settings. I enter the monitor, break 080d, then x, RUN, which enters the monitor, then g, and first part of the demo runs, then g, which runs the second part with the DIGI and Vocoder. When the vocoder starts, I hit ALT-H to enter the monitor, and I do a dump. When I execute x the demo continues as expected. Now I powercycle the emulator, enter the monitor, and do an undump, followed by g. The demo continues running, I then hear the Vocoder...

I'm using GTK3VICE-3.10-win64.zip . Cannot find any 'trunk' version', maybe you could try to reproduce with this release version?

Did you try this PRG? As it might be related to either a SID or CIA specific issue.

OK, so if reSID is still in the release version of 3.10, then that can't be the source of the issue. Any other idea what this can be? Or is this accepted behavior?

Can't find a Setting for that; how to select reSID instead of reSIDfp?
