Bluetooth audio stutters horribly when trying to use A2DP. The HSP
profile works okay, but the quality is horrible then.
This has been the case for as long as I can remember (at least from
Ubuntu 14.04 days or so, probably earlier), with multiple laptops and
multiple Bluetooth headset models. Everything works fine with Android,
so it's the Bluez/Pulseaudio/Alsa stack, whichever component.
At present time using Ubuntu 18.04 LTS with latest upgrades, Bus 002
Device 010: ID 04bf:0309 TDK Corp. Bluetooth USB dongle and a ATH-M50xBT
headset but as said, this is hardly specific to these versions and
pieces of hardware.
