When using a piece of audio in your blender file (VSE) and you enable audio scrubbing, every time the value of the exposure (or gamma) slider changes the audio at your current frame plays.

#97003 (Regression: Blender doesn't allow to animate any Colormanagement setting (e.g. Exposure)) / 35aedd87e7 are probably related

Nope, this was also the case before 35aedd87e7.
Updating colormanagement settings just happens to notify the sequencer, which in turn seeks the audio.
Would still think this is somewhat a bug.

Don't think this is because sequencer is notified. This happens with other properties as well like use_simplify or use_freestyle which do not update sequencer. These do tag scene dependency graph for update. Scene is also tagged in rna_ColorManagement_update. WM_main_add_notifier should cause only redraw.

I guess this could be fixed if sound scrubbing would be handled by scrubbing operator. I can try to do that.

Ah, OK, so it is the (too general) tagging of scene via DEG_id_tag_update(id, 0)

@Sergey suggested P2882 in related #97003, seems to fix the issue here, too

That sounds reasonable as fix. My thought was to untangle sound code just a tiny bit. and maybe learn something in the process. Since have I started already, I will submit fix too.
