Also for a ich6 sound device? Thought the msi interrupts was a 'pass
through' setting when you use the hdmi audio device? Anyway, it's not
listed in regedit in the PCI tree as the amd & virtio devices are so not
sure what to do.
I have to set it to CD quality, any better or worse and the crackles get
really bad

Also ensure msi Interrupts enabled.

That would be interesting to see indeed. Actually I bought the
RX460 because first I wanted to use my old HD7850, but then my pc
didnt even want to boot (linux, didnt try windows). It just hanged
seconds after grub loading with a lot of those PCIe Bus Error's.
Then I tried a couple Nvidia NVS295's I had but I couldnt get them
to work properly (driver issues which caused mismatching colours).
Probably there is just something wrong with that MSI RX480, as it
gave those PCI-E Bus Error's also when it was the only GPU in my
system (while I was waiting for the RX460). But then again, it's
strange that the rom could be extracted correctly with GPU-Z under
Windows.
I did a Unique Heaven test and the results where not bad, ~1350
points and 53fps. But during some scenes it seemed the camera
movement slowed down and then sped up significantly a couple of
times. It didnt look like that was intentionaly but that said
there was no drop in fps. Will do some more tests tomorrow as I am
also not yet really happy with the sound quality (too much noise
sometimes).
Yes, I extracted the uefi bios from
edk2.git-ovmf-x64-0-20170120.b2426.gaa961de.noarch.rpm. See xml below.

I think you have a tougher time because you have two AMD cards.
I am able to blacklist the AMD driver completely because my
"other card" is Intel.
Are you using the uefi bios for your virtual machine?

depending on the Polaris being a reference card
Thanks for your comments, but it seems the MSI Gaming X
series is not a reference card (its factory overclocked).
So the vBios being bricked by the manufacturr should be
also kept in mind.
I dont think this is the case here, as using GPU-Z under
Windows shows a valid EFI rom. It seems a Linux issue only, I
have submitted a case with MSI to see what they say.

Thanks, if I add the rom (the one I saved using GPU-Z under
Windows) my display turns on.
Unfortunately it didnt work then yet, as my dmesg was flooded
with the following message:
vfio-pci 0000:01:00.0: BAR 0: can't reserve [mem
0xc0000000-0xcfffffff 64bit pref]
This was caused due grub loading vesafb for the RX480 as the
graphical terminal was enabled. So in /etc/default/grub I had
to add GRUB_GFXPAYLOAD_LINUX="text" and disable
'GRUB_GFXMODE' (not sure about the last one as maybe thats
implicit but it doesnt hurt either).
Unfortunately that does mean I cant use ddccontrol it seems,
as that complains about missing a framebuffer driver.
Therefore I've also asked Asus whether they plan to support
choosing the primary vga slot like Gigabyte does and they
said 'they will discuss this internally'.
My Asus support agent actually had never heard of vfio before
and repeatedly said that Asus only supports multiple GPU's
when using SLI/Crossfire. So maybe if more people would
contact their local Asus support agent and request this
feature they are more willing to look at it? Who takes the
hint? ;)
I had to install the driver twice as the first time the
install failed, but at the moment the GPU appears to be
working correctly. Now first on to sound before I do some 3D
testing.

In the mean time, do you know which bios revision
your card has?
The other revision is

So is it 113-MSITV341MH.151 or 113-MSITV341MH.152 ?

That's a simple question but a difficult

Anyway, I got the following results after
