Hi Everyone, thanks in advance for you help and suggestions.
I’ve been running my kvm/qemu virtual machine with an RTX 2080 and a VIA USB 3.0 PCIe controller passed through to Windows 10 for quite some time, but have never been able to get a USB audio device to work with it.
If I select the USB device in Discord, then the whole USB controller stops working until I reboot the host. If I only use a headset as an output device, then it may work for a minute or so, then go all distorted and cause issues in the VM where apps will freeze while it disconnects/connects itself. I’ve tried an Astro A50, a regular audio device with optical output and an Astro A20. The VM behaves the same way for all of them.
Note however, I have a 2.4 GHz wireless adapter, Bluetooth 4.0 and a Serial device all plugged into the USB 3.0 card and they’re working fine.
Google hasn’t offered much success in finding anyone who’s had an issue similar to this so I’m not sure where to begin with troubleshooting.
At this point I’m not sure whate other information I can provide, please let me know if you need to know more.
