If you don't do this, you will have to attach the Bluetooth controller
manually to `disp-sys-audio` after it has started and also run `blueman-tray`.
#### How to attach the Bluetooth controller to the AudioVM persistenly
If using Bluetooth, you probably want to have it persistently attached to the
AudioVM. Bluetooth devices are held by the USB stack, thus you need to attach

[not be able to start](https://github.com/QubesOS/qubes-issues/issues/8877)
without first starting the backend holding the USB stack. You can move the
controller from the USB qube to the Audio qube, but this would decrease your
system security.
First, start the qube holding the USB stack:
```sh
qvm-start disp-sys-usb
