Hi , I am testing 6.3.0 rc4 an trying to pass thru the (onboard)sound card but get the following error :

You wont be able to pass that through when there are other things in the same IOMMU group.

 

If youve not enabled PCIe ACS Override in Tools>VM settings, give that a try and see if it gets its own IOMMU group. If not, you'll not be able to pass it through to a VM.

You'll need a seperate PCIe sound card (choose carefully, Some dont play nice). Or if you pass through a PCIe USB card, use a USB DAC instead connected to a port on there instead.

I  enabled the PCIe ACS Override setting , but the soundcard is still in IOMMU group 10, does anybody have some advice for a sound card ( USB od Pci-e)

FYI - you may have better luck posting in the KVM section rather than in prerelease support.

I had the same issue; you won't be able to pass-through the sound card that is grouped with other devices. You will either have to invest in a separate sound card or use HDMI audio from your graphics card. You could post in other forums but I do not believe you will get anywhere.

 

If you do go the route of a separate sound card, please double check your motherboards specifications on how the PCI (PCI/PCI-e) lanes are configured because it will bundle the sound card with another group which has another PCI device in it depending on that configuration and depending on your device assignment to VM(s) that might not be the solution. This happened to me and hence stopped me from being able to use an external sound card. My mobo is an Azuz z710-a.

 

 

I have bought a Asus Xonar ( C-Media Electronics Inc CMI8788 [Oxygen HD Audio] | Multimedia audio controller ) and everthing is working :-)

My mobo is an B150M-BAZOOKA.

the failsafe option is to use a USB DAC and use it with a passed through USB controller.

That is the first successful audio card pass through I have seen!

I'm using Asrock x99 and passing through my soundblaster Z PCIe card with no issues. Much better than the on board realtek btw!

Yeah, a lot of people have had trouble passing through this card and I'm glad to hear it worked for you. Might be because of the updated QEMU and libvirt versions in the 6.3 RC series as I think most have tried on 6.2.4 and earlier versions of unRaid.
