MacBook Air M1, Sound Device Connected in Bluetooth, but not showing in Sound.

Hi,

I have a MacBook Air M1. I am trying to connect a bluetooth audio device, firstly its getting disconnected on it own, MacBook and Audio Device both have more than 70% charge, bluetooth device works find with iPhone.

I have tried connecting other bluetooth sound device, getting the same problem, I connects it and it gets disconnected automatically.

After trying to do connection many times it finally connects to bluetooth but the device does not show up in Sound Section and cannot be used while playing YouTube or anything else.
