I am running Arch Linux, ACS patch on a Skylake system. I have some
audio pop and crackle so wanted to try passing a sound card instead of
routing the audio from my monitor to my speakers. I purchased an Asus
Xonar PCI DGX. Chip is CMI8788. I can boot the host with it, or my USB
card. But not both. Error I get is as follows.

I added the address for all devices to my VFIO.conf under modprode.d
using options vfio-pci ids= to hopefully leave them only for the guest.
But I doubt that is helping because I can start them with one or the
other just not both. Other than the pop and crack occasionally the
guest runs great. Below are my IOMMU groupings with IDs. I am running
out of ideas, not that I am an expert and could use a bit of help.
