I can confirm that this issue has been resolved by @rachid596 over a team-viewer session. The solution as suggested was a custom kernel loaded onto the Unraid flash drive and after a reboot and passing through the onboard audio i had fully working sound within my Windows 10 VM. No more Unraid crashes and tearing my hair out. I just hope the Unraid folk patch this in the next update as it is most certainly a bug with an x570 board when paired with the Unraid OS. Thank you once again to @rachid596

Is it possible for me to grab a copy of your kernal and use it on my own machine? I've never patched or built a kernal before. Or is that something that shouldn't be done?

I've got an Asus Rog Crosshair Viii motherboard and im paired with an MSI 2070 super GPU. Motherboard BIOS is up to date, running latest stable unraid. I've had to do the PCIe ACS override option to get Windows 10 to accept my GPU. Otherwise it just won't pass through. (i think because the GPU has a usb controller and serial bus controller on it as well as the regular gpu and audio under the original iommu group and i cant figure out how to pass the 2 additional through to the VM). So on to the problem... i have the 2070 selected for GPU, then i select the 2070 for audio pass through and when i select a 2nd sound card (my mainboard's sound) and start the VM it stays on stopped (with the spinning icon) and the VM section of unraid hangs and becomes completely unresponsive. If i try shut down the VM it doesn't give me an option. When i open a second page and head to the main dash it shows my VM as "paused" and if i try start or stop it just hangs the dashboard page as well. Eventually all of unraid hangs and i need to do a hard reboot to get it going again. If i remove the onboard audio the VM boots up fine. for reference im trying to pass this through: IOMMU group 38:[1022:1487] 0b:00.4 Audio device: Advanced Micro Devices, Inc. [AMD] Starship/Matisse HD Audio Controller Any suggestions for audio short of forking out for a pci-e sound card?
