I'm not really sure if is pulseaudio of bluez issue. Playback (from Gnome Settings sound test and Firefox), volume change, mute/resume is delayed for 2sec or bit more. I've verified this on two Ubuntu 20.04 laptops. To verify the AV receiver, I've paired MBP 2019 with OS X Catalina 10.15.7 and there are no audible delay.
