The only thing that ended up fixing my usb headset was purchasing a PCIe USB 3 card and passing that through. Works like a charm, and supports hot plugging. I didn't want to do the trial & error in bios trying to split up the onboard controllers. Despite having 4 usb buses listed, every port (front panel and on the motherboard, usb2 and usb3) was showing up on the same bus as the unraid flash drive.

The Nvidia audio had the similar static, but I fixed that by enabling MSI and no more static (it isn't perfect audio, but no static anymore). Thank you. Could you elaborate on "isn't perfect audio"? MSI didn't solve my issue (improved, like you said, but didn't "fix"). I've got a Marantz A/V receiver and expect every audio format to perform exactly the same whether it's played from a VM or bare metal. It's unfortunate that I purchased unraid for exactly this purpose and it doesn't work. Edit: I don't mind adding a PCIe USB controller if required to fix my usb audio, but hdmi audio is a deal breaker in my application

You should be able to experience hardware related noise as you describe whether there's virtualization going on or not. If the OP used that exact headset, port, and OS (bare metal) without issue, it points towards kvm or config. That's what's going on with mine at least.

Did the Nvidia audio ever exhibit similar static? Can you confirm that the Nvidia static actually went away with MSI enabled? Because I spent hours thinking it was just my usb headset. Removed it, and now I have the exact same issue on the HDMI audio. DPC latency is coming back terrible. I'll follow your thread closely.
