Description sorbus 2023-07-24 18:10:44 UTC 
I use bluetooth headphones (jabra elite 3) with an HP laptop. 
With kernel 6.2 everything is OK.
With kernel 6.3 or 6.4, the sound is choppy or jerky. 


Reproducible: Always




I've run "sudo journalctl -r -u bluetooth.service" for each kernel (6.3 same result as 6.4)

see bluetooth_6.2.txt and bluetooth_6.4.txt

-> DISABLING WIFI POWER MANAGEMENT SOLVES THE PROBLEM.
