Does it work when

you set Playback > Sync > Play Every Frame OR
you set Preferences > System > Sound > Audio Device to None (or something else? what is this set to at the moment?)

@neXyon : mind checking? I know there are other reports, but this one does not involve imported audio at all and still blocks playback, so will set this to high prio

Please check if this also happens in the Blender 3.0.0 Alpha (https://builder.blender.org/download/daily/). The bug should be fixed there.

Hm, I swear I tested in 983280b014, but now cannot reproduce anymore (will try a restart soonish).
I also see this in my console (with no trace to blender sourcecode?):

Released audio card Audio0

OK, so even after restart, I cannot reproduce fully now [mystery to me].
I do get a slight stutter though, so maybe that is related.

@viadvena : how is it for you? Do you have the issue in https://builder.blender.org/download/daily/?
@neXyon : which were the commits in 3.0 (these could/should be backported?)

@lichtwerk

you set Playback > Sync > Play Every Frame

Doesn't work

set Preferences > System > Sound > Audio Device to None (or something else? what is this set to at the moment?)

Set to OpenAL device and it's working fine - sound and animation in all scenes (but it looks like the animation is a bit slower in playback) - it helps for the moment.
Set to None device is helping too with the animation in scenes.

Please check if this also happens in the Blender 3.0.0 Alpha (https://builder.blender.org/download/daily/). The bug should be fixed there.

3.0 just fine!

OK, @neXyon : so this is just about backporting your fixes, would be nice to know which these were (and if they can be backported at all)

Yes that should be possible: a112adf16a (not sure if that one made it already?) and a217e043be should do it.

Apparently both have not been backported yet, added them to the list #88449 (Blender LTS: Maintenance Task 2.93).
So these will (hopefully) be available with the next LTS release.
Think we can close this task now, thx everyone involved!
