Is brokenish I think the BCM firmware is shit.
Used older BT usb dongle that came with something:
Bus 006 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Run: hciconfig hci0 down . . . Could not find a clean way to disable this thing. Probably should stuff it in systemd one-shot.
Error trying to play a test sound. The system said: "No such driver"
