how to connect USB-Audio adapter in order to use Mic to VM (Windows)

xentester123

The VM installed with Windows OS.
Right now the Sounds settings - Recording has no Mic.
I have USB-audio adapter pass-thru, then a microphone is attached to the jack.
however, the Mic is not listed still.

I can use this USB-audio adapter to VMWare workstation.

XCP-ng is far from being similar to a Type 2 hypervisor (like VirtualBox or VMware workstation). It's meant for servers, not desktop VMs with multimedia.

Also, the jack on the physical machine is probably only visible in the Dom0, not the VM. I wonder if you can pass the sound card device in PCI passthrough directly to the VM, that might do the trick

@olivierlambert
do you have guidance steps on how to do it?
i can make it works easily on VMWare workstation. The windows detects the USB media.

olivierlambert

Again, VMware workstation is a type 2 virtualization solution, so it's very different than a type 1 "server virtualization" platform.

Check https://docs.xcp-ng.org/compute/#pci-passthrough for more info on PCI passthrough

i followed the guidelines but did not find the device when sending command in host CLI "lspci"

Just there in your lspci:

0b:00.3 USB controller: Advanced Micro Devices, Inc. [AMD] Renoir USB 3.1
0b:00.4 USB controller: Advanced Micro Devices, Inc. [AMD] Renoir USB 3.1

This is your USB controller, using 2x PCI addresses (probably half of the ports are on the first and then the rest on the second one). You can pass it through your VM.

@olivierlambert
i have pass thru the USB as screenshot on above.
however windows does not see the mic still.

olivierlambert

USB passthrough is not PCI passthrough. As I said earlier, what you can try to do instead of USB passthrough, is to directly PCI passthrough the USB controller to your VM.
