Add ability to change audio device type
This needs support in bluez similar to Alias
that would override the audio class and/or appearance.
This would fix icons and device type as used in Pipewire as used in the Sound settings, and gnome-shell's sound level and keyboard shortcuts popup. Depending on the setup, this could also be considered when making decisions for audio routing.
