Hello all,

I have a GMKtec K9 with a core ultra 5 125 H chip in it that I am using for a OBS production studio. I am running Ubuntu 24.04. Everything but sound is working great. Kernel is the 6.8 standard for 24.04

When running lspci I see the sound card is detected

00:1f.3 Audio device: Intel Corporation Meteor Lake-P HD Audio Controller (rev 20) (prog-if 80)
DeviceName: Onboard - Sound
Subsystem: Conexant Systems, Inc. Meteor Lake-P HD Audio Controller
Flags: bus master, fast devsel, latency 32, IRQ 16, IOMMU group 14
Memory at 48202c0000 (64-bit, non-prefetchable) [size=16K]
Memory at 4820000000 (64-bit, non-prefetchable) [size=2M]
Capabilities: [50] Power Management version 3
Capabilities: [c0] Vendor Specific Information: Len=14 <?>
Capabilities: [60] MSI: Enable- Count=1/1 Maskable- 64bit 
Kernel driver in use: sof-audio-pci-intel-mtl
Kernel modules: snd_hda_intel, snd_sof_pci_intel_mtl

So it looks like the card is detected. Looking at dmesg I see this

But apay -l shows:

aplay: device_list:277: no soundcards found...

Does anyone have any thoughts. I'm not finding much with google.
