Hello! 

Thank you in advance, ive had several days of trying to tackle this issue. Im in the process of creating a emulation VM on windows, with some gaming dabbled in there. Ive got everything working except for passing through the audio portion of the GPU, it throws error 

 

Execution error

internal error: qemu unexpectedly closed the monitor: 2023-09-12T17:49:46.783708Z qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:21:00.1","id":"hostdev1","bus":"pci.0","addr":"0x6"}: vfio 0000:21:00.1: failed to setup container for group 86: Failed to set group container: Operation not permitted

 

Ive enabled both multifunction and downstream, as well individually enabling. Ive enabled unsafe interruptions. SeaBIOS or OVMF, Q35 or i440fx. core isolation and not isolated. Honestly i just dont quite know how to fix it and hoping someone might have struggled in the same boat and can point me in a direction. I will attach my diagnostics, as well as my XML layout. Please let me know if you have any questions at all and ill try to help.

 

Thank you again!!
