editar o ficheiro /var/lib/bluetooth/3C\:77\:E6\:EB\:A2\:EE/C0\:2C\:A1\:F8\:03\:29/info e acrescentar no final o que se segue:
[ConnectionParameters]
MinInterval=6
MaxInterval=9
Latency=0
Timeout=216

[bluetooth] module-bluez5-device.c: Skipping 10841 us (= 1912 bytes) in audio stream

I was encountering this same issue on Gentoo. It appeared to be at random times but persistent once it started. I realized that it only happens if 'gnome-control-center bluetooth' is open. I would often leave this open after pairing the device, not really thinking about it. As soon as I close it the "module-bluez5-device.c: Skipping..." messages stop and the choppy sound goes away.

Posting in case it helps track this down.

nano /lib/systemd/system/bluetooth.service
ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap

stretch:
nano /lib/systemd/system/bluetooth.service
ExecStart=/usr/lib/bluetooth/bluetoothd -E -d
systemctl daemon-reload
systemctl restart bluetooth.service
