@neXyon Should this be confirmed as known issue or bug?

@StickMeister125 , can you comment the audio device you are on (Edit -> Prefernces ->System ->Sound)?
Presently ~4 reports are reported on tracker which looks almost similar.

#88887 (Audio causes issues with Playback when PC put to Sleep, Hibernate or when Screensaver appears)
#88879 (Choppy audio)
#88875 (the video sequencer imported sound will not work when scrubbing through frames)
#88876 (Audio Static and Glitches in Blender and other applications on computer, when I play the Blender Timeline.)

(Anyways, I tried with diffrenet Sound API's and I am not able to reproduce this)

I can reproduce this with wasapi. So I could confirm this, I wanted to rather clarify where this report is on range from feature request to bug.

Ok, I can't really reproduce this on my setup here, but I have some ideas.

Could you first try to enable caching for the sound strips (you already have strip properties open in the video, where you enabled "Display Waveform"; there under "Source" you'll find "Caching", check that box for all sounds); does that help?

If not, @iss please try this hack, if it helps at all:

@neXyon Sorry I got a bit confused and I thought, this is #88887 so I was checking issues with hibernation.
So re-checked again:

Doesn't help

If not, @iss please try this hack, if it helps at all:

This works, but when I minimize and maximize Blender window, audio scrubbing stops until start/stop playback.
It seems to stop working even after some time delay.

It's a hack, but this behavior is still weird. Can you try D11778 and check if that solves the issue better? That's a more proper fix.

Ok, @iss doesn't have the issue anymore in the current master. @StickMeister125 can you try if you still have the problem in the 3.0 alpha daily build: https://builder.blender.org/download/daily/ ?
