That's good news! So the Mk2 fixed the multiple device issue? You can find the link in the original post, what it says is

I'm using an Asus PRIME X470-PRO. I was using another board at the time of the righting of this post (mentioned in original post). I understand that not all motherboards use the entirety of the PCIe Bus when many devices are used. My guess is that the "Strix" line doesn't support PCIe as well as the board I just mentioned. I noticed this when I tried to add a third card to the last slot and I started to get the same PCIe Bux limitation on the last card. I suppose it's a good reason to go with a ThreadRipper. In my case, I managed to pass a 2070 Super and a capture card to the VM, but that's it. I can't pass in a USB hub so for the webcams I'm using Unraid's USB device selector prior to booting the VM.

I only have this [12ab:0710] 0a:00.0 Multimedia controller: YUAN High-Tech Development Co., Ltd. Device 0710 I passed it through using PCIe ACS Override under "Both", under the Advanced VM Manger settings.

Hey I solved the issue. I changed the motherboard. It now supports the passthrough and works like a charm

Hey there everyone, I've recently managed to create a Windows 10 VM for streaming and I managed to do a passthrough of an ElGato 4K60 Pro Mk.2 using vfio-pci binding and alongside a Nvidia 970. At start I was getting an image issue since I was getting an odd green screen and I began to look into using ElGato's 4K Capture Utility to see if I got the same image that I was getting on OBS and I did... I started looking into the setting I noticed that if I changed the EDID mode to 'Display' the error would be fixed. Now, here's what I found so far and where I'm asking help. After looking into the matter, I realized that if you go to higher resolutions, the capture card will not work correctly. That EDID mode pretty much states the resolution of the capture, and the 'internal' capture is 4K. When it goes that high, it doesn't work giving the green bars from the image above. I tested this by trying to capture a high-resolution display and it gave the same issue. I looked up this error, and lucky enough I think I found the problem. It seems that the VM that was created is not passing in the Capture card with the correct PCI-e Bus. I checked the motherboard specs, and it says that that all PCI-e slot is a Gen 3, it shouldn't be a problem (Asus ROG STRIX B550-F GAMING second PCI-e slot). Here's the discrepancy I'm trying to resolve. The ElGato Documentation states that the card should sit on a Gen2x4 connection. But mine is registered as Gen2x1. Is there a way I can change the specs on how the card should be passed through and force it to be the correct PCI GEN? Elgato 4K60 Pro MK.2 - Green or distorted video – Elgato VM

I had this same issue and what I did was to pass the drive vias it's IOMMU Group and assigned the drive as the main boot drive (the first it checks on boot). If it's not the main boot drive, I get that message. Hope this helps.

Hey guys, I managed to update my XML to have the sound card set on a separate bus. I managed to boot the VM with the sound card but now I'm getting this error. I tried changing the bus and I still get the same error.

Hey guys, I stumbled on the same issue and was wondering if there was a solution. I did made as far as getting the error out of the way. I found this post on the forums and it cleared the error.
