Summary0001460: WASAPI: Stutter on playback when clicking button 'Play From Start' or pressing F6

On my system: Ubuntu 20.10, wine-6.8 (Staging), PulseAudio 13.99.2, emu01k1 sound blaster live soundcard, Ryzen 3600 processor

Playback noticeably stutters when I start playback with 'Play From Start' feature, either by clicking on the button or pressing F6.
It doesn't stutter when I press F7.

DBZ FOREVER!!! !!! !!! !!!

Steps To Reproduce

Open a song with a sound at the start such as a kick drum.

Start playback with F6.

It sounds like the kick drum plays twice really quickly.

Additional Information

Looking at Pavucontrol, the 'audio stream' number for openmpt increases every time I start playback via F6.
But it stays the same when I start playback via F7.
I thought that was interesting and might be relevant.

I tried capturing audio into audacity by recording from 'monitor of emu10k1' to give an example of what I'm hearing.
Interestingly the captured audio is also bugged, but in a different way from what I'm hearing - I hear the sound stutter as if the first few ms are played twice, but in the recording it's like the first few ms aren't there at all.


TagsNo tags attached.
Has the bug occurred in previous versions?
Tested code revision (in case you know it)
