HI,
usually if I try to pass my matisse Audio controller my VM hangs, and this seems to be a common problem on AMD chipset (also older than mine)

if I comment this line:

[device "audio0"]
driver = "ich9-intel-hda"
bus = "pcie.0"
addr = "1b.0"
VM starts and in web interface I have this log in Tasks:
kvm: vfio: Cannot reset device 0000:23:00.4, depends on group 30 which is not owned. kvm: vfio: Cannot reset device 0000:23:00.4, depends on group 30 which is not owned. TASK OK
Problems with audio are the same (bad audio , not stable, scratchy
May I debug with others data to give here?

Thank you
 
Hi,

The audio dev "audio0" is a virtual device and not a physical passthrough.
The "23: 00.4 Audio Device" physical audio device is not isolated in its own IOMMU group.
Please send the output of

Code: 
find /sys/kernel/iommu_groups/ -type l
qm config <vmid>

In a Windows 64 bit Realtek USB 2.0 internal audio is perfect:

I can pass easily all my controllers in my rig but audio in osx is not working
To see audio device in OSX I have to pass single USB device in this way:
usb1: host=xxxx:xxxx
if I pass 23:00.4 controller I cannot see Realtek audio device
in usb single way I can see and select but audio is bad

I think of a sort of interferences between usb and audio bridge

If I comment audio0 device , I can pass 23:00.4 controller without FLR kernel patch

attached my lspci -nnk output:


Thank you again for your attention

Ok the IOMMU group is isolated.
But you have the Audio Dev in two different VM's.
Do you run them parallel?

No
I run 1 at once
OSX VM has audio problem
Windows 10 64 bit no problem at all
I think it is an OSX internal audio problem but I do not know how to solve for now
 
That could be possible. Maybe a Bios Update of the Mainboard will fix this in the future.
