UPDATE:

I bought the Xonar DG (DGX is the same but on PCIe). Plugged it in and it recognized as:

04:00.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 41)
05:00.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]

/sys/kernel/iommu_groups/13/devices/0000:04:00.0
/sys/kernel/iommu_groups/13/devices/0000:05:00.0

But it worked straight away when i passed only 5:00.0 through. Now i am happy

Most likely your device doesn't support the INTx disable, but you can check that with the attached script.

Save it somewhere and SSH to your server and go to the folder you saved the file.

You now get a message if INTx disable is supported or not.

If you want to see what is on the same IRQ to see if you can disable that device, issue this command and post it here:
cat /proc/interrupts

not available

intel_pstate=disable

What's that bit in bold for? Tried it without that?

That is just to fix the non throttling of Intel CPU's.

[glow=red,2,300]HEY EVERYONE!!! COME AND HAVE A LOOK AT THIS, ANOTHER CLUE ABOUT 6.2!!!![/glow]

Yeah, look at the Clue and my wierd MoBo

January 13, 2016

Tried it with both of your Configs. (Mine doesn't say (GUI) at all)

default /syslinux/menu.c32
menu title Lime Technology
prompt 0
timeout 50
label unRAID OS
  menu default
  kernel /bzimage
  append intel_pstate=disable vfio_iommu_type1.allow_unsafe_interrupts=1 iommu=pt pcie_acs_override=downstream initrd=/bzroot
label unRAID OS Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Memtest86+
  kernel /memtest

Both of the times the same error as without your config. :'( :'( :'(

Doesnt work when i remove the internal audio.

Also tried it with qemu params instead of hostdev. same error

January 12, 2016

I dunno tbh. let me test without it

January 12, 2016

By the way, why would you want to pass the onboard audio through?

Because i want audio ?

I think i misunderstood the question

January 12, 2016

It seems you are out of luck. The Xonar card is still in the same group as the bridge and that means you will not be able to pass it through.

Unless jonp has something up his sleeve

I hope so.

The other PCIe slot i have doesnt work at all. not even posting

Enabled ACS override didnt crashed my Windows on is own now.

Just tried it with Xonar, internal Audio and Graphicscard audio passthrough.

Same error as before:

I have the PCIe Version.

Will post my configuration later when I am back at home

(i passed the graphics card and on board audio via the drop down menu. Didn't passed the amd audio there)

When you get back home, enable ACS override, pass through the AMD HDMI device also and check if your VM is stable. Then you can go ahead and pass through the Xonar. You could try the Xonar also right away just to see if the ACS override works, but better take one thing a time.

I will do that right now (Currently backing up my win vm disk)

I have the PCIe Version.

Will post my configuration later when I am back at home

(i passed the graphics card and on board audio via the drop down menu. Didn't passed the amd audio there)

January 11, 2016

I'm passing through a HD7850 (my only graphics card, don't have internal graphics also) and currently the on-board sound card.

EDIT:

Also forgot to say that I have only 2 PCIE slots

Have you enabled the ACS override setting in Settings --> VM Manager?

I tried ACS override once but then my Windows VM freaked out.

January 11, 2016

Hello unRaid-Community,

------------------------ Current Status

Doesn't work with ACS Override. Passed through Onboard Audio + Graphicscard Audio.

Waiting for JonP?

------------------------

i have a problem with passing my Soundcard (ASUS Xonar DGX) to my Win10 VM.

06:00.0 PCI bridge: ASMedia Technology Inc. ASM1083/1085 PCIe to PCI Bridge (rev 03)
07:04.0 Multimedia audio controller: C-Media Electronics Inc CMI8788 [Oxygen HD Audio]

/sys/kernel/iommu_groups/13/devices/0000:06:00.0
/sys/kernel/iommu_groups/13/devices/0000:07:04.0

If i only add the hostdev entry for 07:04.0

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x07' slot='0x04' function='0x0'/>
      </source>
    </hostdev>

i get the following error on Launch

internal error: early end of file from monitor: possible problem:

And if i pass the Bridge also, i get the following error:

Failed to bind PCI device '0000:06:00.0' to vfio-pci: No such device
