Intel 245k iGPU passthrough - no hdmi audio

adolfotregosa · 2026-08-24T12:57:30+0200

Did anyone manage to get HDMI audio working using a similar CPU/iGPU? Yes, I have both the iGPU and audio device passed through to the VM. Inside the VM, I can see in dmesg that when snd_hda_intel maps everything, the HDMI/DP ports are missing, only the analog audio shows up. I remember in the past having to give the audio device a romfile as well, but as far as I know, there's none available for Ultra CPUs.

Thank you.

I'm using an Intel Core Ultra 265k, and I tested this on Windows 11.

It appears that the HDMI audio device isn't displayed when no monitor is connected to the HDMI port, but I've confirmed that it does appear once a monitor is connected.

Code:

mv 6-14-qemu10.rom /usr/share/kvm/

qm set 929 -args '-set device.hostpci0.bus=pcie.0 -set device.hostpci0.addr=0x02.0 -set device.hostpci0.x-igd-gms=0x0 -set device.hostpci0.x-igd-opregion=on'
qm set 929 -hostpci0 0000:00:02.0,pcie=1,romfile=6-14-qemu10.rom
qm set 929 -hostpci1 0000:80:1f.3,pcie=1
qm set 929 -cpu host
qm set 929 -bios ovmf
qm set 929 -machine pc-q35-9.2+pve1

Interesting. You are using 6-14-qemu10.rom and not ultra-1-2-qemu10.rom
Let me try it out.

@uzumo Unfortunately no hdmi audio but hdmi display works with 6-14-qemu.rom, ok.. lol

HDMI audio output is missing on the VM.

It works like this on Windows, but it might be different on Linux.

If I have time, I’ll try it on Linux too, but I’m not very familiar with Linux (especially the GUI version, which I’ve only recently started using), so I don’t think I’ll get results right away.

*Ideally, someone else would come up with the results in the meantime, though.

If you don’t mind, could you let me know which distribution you’re using?
If I'm going to try it, I'd like to try the same thing, so...

I've tried Windows before, and I also didn't have HDMI audio. It's a very simple test: boot the CachyOS live ISO. You'll either have audio or you won't when you reach the KDE desktop. What motherboard are you using with your 265K?

uzumo · 2026-08-24T16:22:57+0200

I'm using the Asrock Z890 Pro RS WiFi White.
As for the OS, I'll download it and give it a try.

I don't get it. My Bios is now 3.24, still no hdmi audio. I installed windows 11 and those two "HD Audio Driver for Display Audio" never show up for me. You will have audio in linux. Do you have anything special on proxmox ? custom kernel? pve-test enabled ? anything ?

uzumo · 2026-08-24T17:30:52+0200

I tried booting the LiveCD on the exact same virtual machine, and the result was the same as yours.

I'll try a few different things.

I tried booting the LiveCD on the exact same virtual machine, but I got the same result.

I'll try a few different things.

Sometimes it only shows up a little more bellow. Did you see any audio device on KDE ?

I tried switching the driver to “xe,” but it seems the same issue you're experiencing is still occurring.

Code:

There's a line through the speaker icon, and “Playback Audio” is set to “Dummy,” so playback isn't possible at all.

Code:

I think the issue described below—which appears in both cases—is the problem, but I couldn't figure out how to fix it...

Code:

[   26.356501] i915 0000:00:02.0: [drm] *ERROR* GT1: GSC proxy component didn't bind within the expected timeout
[   26.356506] i915 0000:00:02.0: [drm] *ERROR* GT1: GSC proxy handler failed to init
or
[   27.757982] xe 0000:00:02.0: [drm] *ERROR* Tile0: GT1: GSC proxy component not bound!

Since this is what is displayed on the physical machine, we believe the above error is the cause of the problem.

Sometimes it only shows up a little more bellow. Did you see any audio device on KDE ?

There's a line through the speaker icon, and “Playback Audio” is set to “Dummy,” so playback isn't possible at all.

I think the issue described below—which appears in both cases—is the problem, but I couldn't figure out how to fix it...

Code:

Since this is what is displayed on the physical machine, we believe the above error is the cause of the problem.

We can provide any type of Windows-related configuration.

Yeah, pretty much what I see. Do you still have audio in windows 11? I don't. I was never able to see the hdmi audio devices on the device manager.

uzumo · 2026-08-24T18:45:38+0200

I accidentally deleted the disk from the virtual machine I was testing a moment ago, so please give me a moment.
On the N100 I use separately, Windows 11 works with HDMI audio using the same procedure, and since the display is the same, I think the sound should work.

Same over here. I always had hdmi audio working on previous intel cpu/igpu. On this 245k I don't either on windows or linux.

uzumo · 2026-08-24T19:12:31+0200

I tried reinstalling it in PVE using the 265k.

It appears that the audio is playing fine via HDMI.

I have no explanation. I get no audio in windows.

uzumo · 2026-08-24T19:32:00+0200

If there are any differences in PVE and virtual machine settings, I think they’re limited to the version of Windows OS, the drivers being used, and… probably just the monitor.

Just to be sure, please let me check your VM.conf file and the results of running the following command.

Code:

cat /etc/kernel/cmdline
cat /etc/default/grub
cat /etc/modprobe.d/*
cat /etc/pve/qemu-server/<vmid>.conf

・I’m using Windows 11 25H2 Enterprise Evaluation—which version are you using?
・I’m using the gfx_win_101.6647 driver—which driver are you using?
・I’m using the pikvm monitor (with HDMI audio enabled)—which monitor are you using?

If there are any differences in PVE and virtual machine settings, I think they’re limited to the version of Windows OS, the drivers being used, and… probably just the monitor.

Just to be sure, please let me check your VM.conf file and the results of running the following command.

Code:

cat /etc/kernel/cmdline cat /etc/default/grub cat /etc/modprobe.d/* cat /etc/pve/qemu-server/<vmid>.conf

・I’m using Windows 11 25H2 Enterprise Evaluation—which version are you using?
・I’m using the gfx_win_101.6647 driver—which driver are you using?
・I’m using the pikvm monitor (with HDMI audio enabled)—which monitor are you using?

Thank you but I won't use windows, I'll wait for a solution in the future, hopefully.
Even so I did try using your gfx_win_101.6647 driver, same result.
Kernel cmd is untouched from stock. I tried i440 and q35 and all the args related to intel igpu. No audio on VMs, I only have hdmi audio with bare metal.

I'm gonna give up for now.

Intel 245k iGPU passthrough - no hdmi audio
