Thank you for bringing this to my attention, let me help you on this matter.
I understand you are getting choppy sounds through Bluetooth device.
At this point, please make sure there is no other Bluetooth device connected or paired.
You can try loading default settings in Bios by pressing F9 key and save the changes with F10.
Load latest graphics drivers version 4849
Additionally, try reinstalling the Bluetooth driver version 20.0
Please let me know your findings.
