[MX666, playback] Underruns, dropouts or crackling sound

[Denise Jaimes]

Playback on YouTube exhibits occasional popping and crackling every 3-5 seconds when first pairing the MX666 bluetooth headphones. [killall pulseaudio] seems to fix this and provides a temporary workaround, but needs to be repeated every time the bluetooth device is paired.

Didn't have this problem on Ubuntu 21.10. Started to happen after upgrading to 22.04
