When I connect 2 Bluetooth speakers to S20+and play music, audio is slightly out of sync. I am sure this is not a speaker problem because everything different speaker is falling back. But this does not happen always. Issue is only some times.
Figured out that the issue is when one of the speaker is google nest mini. Other speakers work fine even if different brand. Now I have to test with some other smart speaker to check if issue comes only when one is smart and other's not.
