[Proxmox] Onboard audio + GPU Passthrough makes WIndows 10 crash

Software & Operating Systems VFIO

Hello there,
I am running Proxmox host trying to passthrough my motherboard onboard audio to a Windows 10 guest, but every time it boots it crashes on blue screen; I have successfully passed through the nVidia GPU from the first slot, more details following

the lspci --nnk output for the audio card I want to passthrough is

00:1b.0 Audio device [0403]: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller [8086:3a3e]
Subsystem: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller [8086:0041]
Kernel driver in use: vfio-pci
Kernel modules: snd_hda_intel

while the graphic card is

        Subsystem: Micro-Star International Co., Ltd. [MSI] GP106 [GeForce GTX 1060 6GB] [1462:3283]

        Kernel driver in use: vfio-pci
        Kernel modules: snd_hda_intel

grub options are set as follow

GRUB_CMDLINE_LINUX_DEFAULT=“quiet intel_iommu=on pcie_acs_override=downstream,multifunction video=efifb:off”

As far as I can understand each device has its own IOMMU group (12 for the audio card, 22 for the GPU and 23 for the audio device integrated in the GPU), cause from

find /sys/kernel/iommu_groups/ -type l

relevant line output are

/sys/kernel/iommu_groups/12/devices/0000:00:1b.0
/sys/kernel/iommu_groups/22/devices/0000:03:00.0
/sys/kernel/iommu_groups/23/devices/0000:03:00.1

and checking the respective folders are the only device in there

Before trying this I successfully passed through the host video card to the guest, following the indication on both the manual and the wiki;

trying to passthrough the audio card I added to /etc/modprobe.d/blacklist.conf the last line (the previous 3 are for the GPU passthrough)

blacklist radeon
blacklist nouveau
blacklist nvidia
blacklist snd_hda_intel

I also added the second line to /etc/modprobe.d/vfio.conf (again, previous one for the GPU)

options vfio-pci ids=10de:1c03,10de:10f1 disable_vga=1
options vfio-pci ids=8086:3a3e

and updated initramfs, then i edited
/etc/pve/qemu-server.201.conf (201 is my VM device ID) adding
hostpci1: 00:1b.0
(while hostpci0: 03:00.0;03:00.1,pcie=1,romfile=GTX10606Gb.rom is the line for the GPU passthrough)

Without the hostpci1 line the VM boots fine, as long as I try to configure the audio card adding that line I get blue screen on boot.
I also tried installing Windows from scratch, it boots fine as long as the GPU drivers are not loaded, but as soon as I try to load gpu drivers it crashes with blue screen, in both cases with

Stopcode: SYSTEM SERVICE EXCEPTION or SYSTEM THREAD EXCEPTION NOT HANDLED
What failed: nvlddmkm.sys

Also worth noting that the passing through the audio card alone doesn’t make the system crash, and also that I’ve tried that audio+gpu combo and without virtualization it does boot without an issue
am I missing something? Is there something else I should add? How can I circumvent the problem?

Also worth noting that I don’t strictly need to passthrough the audio card, what I really need is getting the audio output in the backplate jacks of the host, in order to get sound on my 5.1 setup, and passing through the audio card is the only way I know of doing it, any other way to do it is welcome

Thank you in advance
Roberto

p.s. the GPU I am passing through is a GTX 1060 Gb, the Motherboard whom audio I wanna passtrough is an Intel DX58SO2 and the CPU is an Intel Xeon X5670, running latest version of Proxmox (installed it about a week or 2 ago)

In a situation like this, I usually try to work around the problem rather than tackle it head on. IOTW., I would use USB or HDMI audio instead of trying to muck around with the onboard audio.

A Xeon X5670? Is this an old Dell T3500/5500/7500 by chance? I don’t think I’ve had trouble passing through Intel audio on those old 5520/X58 chipsets.

4

It’s a Desktop I built years ago, kept upgrading over time, it has a consumer Intel Board (Intel Extreme Dx58so2).
I can’t use a PCI sound card because all the internal slots are taken, with the GPU, a LSI 9210-i raid card, an Intel network card and/or a second video card to passthrough to the TV/a VR headset (still gotta decide on that); the USB solution would mean wasting the onboard audio card, because the other appliance I’m gonna virtualize on that machine won’t use it (a NAS OS like Xigmanas or OMV and a pfsense, and the TV/VR solution will use the HDMI audio), I can do it, but I’d keep it as the last resort; any suggestion on which USB card in that scenario?
I’d rather obviously solve the problem with the onboard sound card to either learn more about proxmox/passthrough and how it works, and what I may have done wrong (First time playing with it)

The fact, I may not have made it clear and I am sorry about it, is that if I try to passthrough only the audio it works flawlessly, same for the sound card, problems arise as soon as I try to passthrough both the audio and the GPU. Imma try passing through another device, maybe the wifi card or the raid card, and see if the Issue still happen

Occasionally I’ve had to grab PCIe IDs with a kernel option, in addition to vfio.conf. So in /etc/default/grub you’d add:

GRUB_CMDLINE_LINUX_DEFAULT="[whatever was here before] vfio-pci.ids=8086:3a3e"

You could optionally add the other devices you want to pass through on this line too.

Final question - If you do “lspci -kv” what drivers does it show grabbing the onboard audio? If it’s anything other than vfio you’ve got a problem.

EDIT: I think it’s a bit odd that your GPU and GPU HDMI audio are in separate IOMMU groups. Can anyone else comment on this? Seems kind of weird, but it’s been a while since I passed through audio.

6

I think the above is your problem. snd_hda_intel is trying to grab your onboard audio as well as vfio-pci. Even though you’ve blacklisted it, it’s still trying to load. Try adding the following to your /etc/default/grub on GRUB_CMDLINE_LINUX_DEFAULT:

rd.driver.blacklist=snd_hda_intel module.blacklist=snd_hda_intel

This will prevent the Intel audio driver from loading from your initial ramdisk…hopefully. And don’t forget to run update-grub or grub2-mkconfig

7

I’ve just finished trying the fix you suggested, my /etc/default/grub now looks like this

GRUB_CMDLINE_LINUX_DEFAULT=“quiet intel_iommu=on pcie_acs_override=downstream,multifunction vfio_iommu_type1.allow_unsafe_interrupts=1 video=efifb:off rd.driver.blacklist=snd_hda_intel module.blacklist=snd_hda_intel”

I updated grub, but sadly I got the same error as above

Meanwhile I tried passing through both the PCI network card and the wifi card with both the GPU and the onboard audio passed through and they work well, it’s seems like that it’s only the gpu+onboard audio combo that is crashing, but I can’t figure out why, or how to resolve that.

I suspected it had something to do with the HDMI audio integrated in the GTX 1060 6GB GPU, so I’ve tried passing through only the video component (deleting the 03:00.1 passthrough) but that didn’t solve the problem as well.

While thinking about how to solve the problem I though, is there a way to use a virtualized audio card instead of a passthrough and still get the output on the backpanel ports of the motherboard? Because I don’t need performance or anything like that, just the 3 jack output for the 5.1 stereo.

8

So can you run ‘lspci -kvn’ one more time and let’s make sure that snd_hda_intel isn’t still trying to grab your onboard audio?

And I’d also suggest trying to take out some of the parameters you’ve entered before the snd_hda_intel ones. In particular, I think the unsafe interrupts option may be causing problems.

You may be right about the GPU and HDMI audio being in separate IOMMU groups. The only way I know to fix that would be a mobo BIOS upgrade, or maybe even downgrade. A different GPU might have them in the same IOMMU group. As a test it might be worth it to try a different GPU and see if the problem persists.

I’d also check the output of the lspci command above to see if any other drivers are grabbing your GPU or it’s audio.

Removing the line didn’t work, still the same error.

The GPU, GPU’s HDMI Audio and Onboard audio are indeed in 3 different IOMMU groups, and there’s no BIOS update available (I’m on the latest version anway), downgrade are not an option too because Intel took down their legacy BIOS. I don’t have any other GPU worth passing through laying around, somehow gotta fix it with this one.

Any idea on how to find out more details on what is causing the crash?

Last time I looked there weren’t any good Windows audio hosts that could use PulseAudio as a network client. Looks like that’s changed.

There’s also a VM config example on the Arch wiki that I can’t copy paste on my phone ATM. I’ll try to add a link later.

Instead of bashing our skulls against this brick wall, I propose we try one alternative you thought of a few posts ago.

Edit: here’s the relevant Arch wiki link:
https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF#Passing_VM_audio_to_host_via_Scream

Ok, this is the way I’m trying to do it, but I find myself pretty stuck bashing my head against the differences between an Arch install with OVMF and a Proxmox Install.

I installed pulseaudio, set it as a service (because I don’t have another user aside from root), enabled and started it, creating /etc/systemd/system/pulseaudio.service

[Unit]
Description=PulseAudio system server

[Service]
Type=notify
ExecStart=pulseaudio --daemonize=no --system --realtime --log-target=journal

[Install]
WantedBy=multi-user.target

but running

systemctl status pulseaudio.service

I get the following output

● pulseaudio.service - PulseAudio system server

I also commented the lines in /etc/modprobe.d files that blacklisted the intel sound drivers, added the -device strings to my VM config files.

-device ich9-intel-hda,bus=pci.0,addr=0x1b -device hda-micro,audiodev=hda -audiodev pa,id=hda,server=unix:/tmp/pulse-socket -device usb-audio,audiodev=usb,multi=on, -audiodev pa,id=usb,server=unix:/tmp/pulse-socket,out.mixing-engine=off

so my vmid.conf file args line looks like this

args: -cpu ‘host,+kvm_pv_unhalt,+kvm_pv_eoi,hv_vendor_id=NV43FIX,kvm=off’ -device ich9-intel-hda,bus=pci.0,addr=0x1b -device hda-micro,audiodev=hda -audiodev pa,id=hda,server=unix:/tmp/pulse-socket -device usb-audio,audiodev=usb,multi=on, -audiodev pa,id=usb,server=unix:/tmp/pulse-socket,out.mixing-engine=off

The Windows OS see the audio devices, but there’s not sound.
I’d like to test the audio in the host, because I suspect the above error s might be the issue, how do I fix that and confirm the audio is working correctly on the host?

So having root as your only system user can be a problem. I’m not sure if it’s the cause your inability to stream audio, but pulseaudio could be confused. It’s used to running as a ‘normal’ user and may not like running as root.

Is having only root as your primary user a Proxmox default? If so I’m surprised.

At any rate, I found this tutorial by @GrayBoltWolf on Youtube for Scream. He usually works with Debian (Proxmox’s ‘parent’ distro) and I’ve used his Debian passthrough tutorial in the past to set up PCIe pass thru on Proxmox. I should note though that I had a full Linux desktop and dedicated GPU. Proxmox can be expanded into a full Debian desktop, or at least it used to have that capability. And an old crappy GPU will do for the Linux side of your solution.

Somehow my machine refuse to boot if I try to start it with two GPUs, now I’m downloading a collection of old BIOSes (because Intel removed everything from their website) ti check if some BIOS update for my motherboard

(an Intel DX58SO2)

says something about multi GPU sopport, I’ll open another topic about it in case I won’t be able to solve the Issue this way.

Meanwhile I kind of surrended on onboard audio and bought a Creative Soundblaster Audigy FX Pcie audio card. The system boots but it’s giving me huges audio artifacts.
I’ll try enabling MSI interrupts and other solutions across the web, in case I won’t be able to solve should I keep asking Here for help or should I open a new topic?

Thanks anyway for the immense support and patience, it’s really am awesome community here!

I’m coming across this topic because I noticed a virus in my system . I kind of feel like it used pulse audio. To escalate privileges on the dbus. It looked like the system proceeded to direct memory write it different addresses across the bus.
Specifically
Usb keyboard
Mouse/TouchPad
Nvidia
Etc

Literally everything that loads -2 zone

Now when I do lspci -Q -vvv
My host bridge controller is giving a sound driver subsystem ID 380b

Lsmem doesn’t show all my memory missing block 13-64 not hidden or error just missing

Also the Intel controller is trying to load expantion rom into virtual environment.

There’s more I forsure have a rootkit. It’s actually persistent between installs.
