Right? I remember trying it on win11, and it fact it seemed different from what we're used to. Not sure about reduced quality... would love a quick recording of the two (though, if you're running win11, that might not be possible

).
As for the reason, the audio is routed through a different audio library than dsound - openal. So the calls to dsound are handled by openal, though, it depends on how well the peeps at dsoal (dsound to openal) have handled this translation.
