Call-for-testing: Asynchronous audio device detach

Hello,

A few weeks I added support for asynchronous device detach for audio
devices [1][2], something that many people with detachable audio devices
(e.g USB) have been asking for for years [3][4][5][6][7][many more...].

Now that 14.1-BETA1 is out, I would like to ask you to give it a try and
let me know if everything works properly.

Christos
