I'm also getting this problem on 12.3.1 on an M1 Max MacBook Pro. Also, my AirPods Max will only play a second of audio before stopping. There's obviously a bug in the connection. Tried all the fixes but still can't get them to work with my MacBook. For some reason they add "-Find My" after the AirPods name after reconnecting. Working fine on iOS devices.

Also experiencing this. Interfaces are working fine on their own, but pure digital mess when used in an aggregate device. Changing sample rate doesn't solve. Work at 48k, M1 max.

Yeah, update has done nothing. I've got the most recent flagship MacBook Pro, and the most recent flagship AirPods Max, and I can't use them together. Feeling pretty robbed at the moment to be honest.

This still isn't fixed in 12.4. M1 Max, AirPods Max.

No change in 12.5. Losing income because of this now.
