I have a tower with intel 9th gen with integrated gpu and a dedicated nvidia 30 series, and I'm passing through the integrated gpu to my virtual machines
Today I updated my system to the latest kernel 6.7 and I lost the sound on my host machine
I still have kernel 6.6lts installed, and with it the sound works without issues
On kernel 6.7 if I disable all the kernel modules related to vfio and iommu, the sound works again
And I use pipewire as my audio server.
Any ideas?

hmmmmm, Am I posting in the correct forum but no one knows how to resolve the problem?

Or no one has yet ran into the same issue.
Compare/post kernel logs between working and not working.

Today I updated the package linux-firmware to the latest version, and the problem persists.
Removing vfio.pci.ids=xxxxxxx from the bootloader parameters resolves the sound issue but disables the gpu isolation, so it is not a real solution
running
inxi -A
returns that the onobard intel sound card has no driver available
For now I'm sticking to the lts kernel until I find a solution
I will not mark the topic as Solved becuase it's NOT!!

I'm facing a similar issue.
On 6.7, my speakers work just fine, but headphones are not detected when I plug them in, and I get no sound. Everything works fine on 6.6.12 LTS.

Interesting!
I am running a i9-19300HX CPU, and also lost sound on the 6.7 series of kernels.
On this machine, the following option needed to be passed in /etc/modprobe.d/alsa-base.conf:
options snd-hda-intel model=clevo-p950
In the 6.7 series of kernel the sound cards were detected in a different order, and there is no sound from the internal sound card.
I have an open bug on the kernel bug tracker=https://bugzilla.kernel.org/show_bug.cgi?id=218409
There is no vfio.pci.ids in my kernel parameters, but I am passing nvida_drm.modeset=0 to get the nvidia card to detect the HDMI port on the laptop.
I'll go disable that and see if it helps in my case. If it does, then that open bug is either a wild goose chase, or will go in a different direction.
Edit: No change on my system, this might be a red herring too.
