not able to passthrough intel onboard audio

[Danny08]

hi,

so i tried to passthrough intel onboard audio but im getting the typical iommu group error:

internal error: qemu unexpectedly closed the monitor: 2018-12-20T21:05:24.547859Z qemu-system-x86_64: -device vfio-pci,host=00:1f.3,id=hostdev2,bus=pci.0,addr=0x9: vfio error: 0000:00:1f.3: group 10 is not viable Please ensure all devices within the iommu_group are bound to their vfio bus driver.

 

This is the group:

IOMMU group 10:[8086:a2c9] 00:1f.0 ISA bridge: Intel Corporation Z370 Chipset LPC/eSPI Controller

[8086:a2a1] 00:1f.2 Memory controller: Intel Corporation 200 Series/Z370 Chipset Family Power Management Controller

[8086:a2f0] 00:1f.3 Audio device: Intel Corporation 200 Series PCH HD Audio

[8086:a2a3] 00:1f.4 SMBus: Intel Corporation 200 Series/Z370 Chipset Family SMBus Controller

 

so, actually i dont have any of these devices assigned to something or is the chipset automatically used by unraid?

i already tried the ACS Override, with the settings downstream and both, but group 10 stays the same.

 

Is there anything i can do or do i have to get the audio out of the GPU?
