There's no way that commit causes change to sound output.

fwiw there used to be an issue with these specific qsound games requesting an invalid (negative?) number of samples, which was worked around as it was outright crashing MAME at the time and nobody knew where / why those requests were originating as they were basically random.

Given recent discoveries I think it's more likely the recent sound.cpp changes in that area have caused this along with the things MASH reported. ( https://github.com/mamedev/mame/issues/3603 )

Will acknowledge for now since it seems there's recorded proof. I wasn't able to confirm on my end after playing ssf2xj for about an hour.

I think this should have been fixed already with the .201 Qsound HLE rewrite, as the original problem seems to be related to the sample position not properly saturating after the refactors to the OLD hle (which has been replaced now).

yes, quite likely
