Using "Galaxy Buds2 pro" , I noticed that a ok sync is at about -0.5s
I applied it during video playback - all is fine.
Then I cancelled it, and applied it to global settings for bluetooth.
Next time I started the app, I again had bad sync - but now selecting -0.5 in the movie/track menu made it worse.
I removed the global BT-delay setting - and now the -0.5s worked as expected.
