You can set up usb passthrough through virt-manager or VirtualBox. After you do that, the guest gains complete control of that usb device and it should work/behave like it wasn't even in a vm. 

I can confirm that you can use USB Passthrough to send the USB sound cards to the Virtual Machine which then can use them without limitations. This is also valid for MIDI USB controllers.

I think that with using the USB Passthrough strategy, the PipeWire could be also tested on VMs.

I will update the test cases.

 

You can get there through "Show virtual hardware details", "Add Hardware", "USB Host Device", then choose a device you wish to hand of to the guest. Beware that the selected device won't be available on host for use while the vm is up and running.

TRIED AND PERSONALLY TESTED, ERGO TRUSTED.

yeah, Thanks...... but this email seams to be strange...

For I didn't ask anything about USB Passthrough or GPU passthrough,I made it work a long times ago, and I wrote my email to apply to join the QA group for contribution...

Anything wrong?
