[BUG] Audio not working on HP Omen Transcend 14 (2025) with Intel Core Ultra 7 255H (ARL) - driver is requesting wrong topology file.

[jkfids]

Description
The sof-audio-pci-intel-mtl driver on the HP Omen Transcend 14 (2025) with the Intel Core Ultra 7 255H (Arrow Lake) processor incorrectly requests a topology file that does not exist. The audio device loads with a "dummy output" because it cannot find the required firmware and topology files, leading to a -22 component load failure. To fix the issue on my end, I manually downloaded the meteor lake files sof-mtl.ri and sof-tml-rt711-l0-rt1316-l3-2ch.tplg from sof-bin and copied/renamed them to the directory expected by the kernel via the commands:

sudo cp /path/to/downloaded/sof-mtl.ri /lib/firmware/intel/sof-ipc4/arl/sof-arl.ri

sudo cp /path/to/downloaded/sof-mtl-rt711-l0-rt1316-l3-2ch.tplg /lib/firmware/intel/sof-ace-tplg/sof-arl-rt711-l0-rt1316-l3-2ch.tplg

Expected behavior
The kernel should load the correct firmware for the audio device, and sound should work.

Environment

1. Branch name and commit hash of the 2 repositories: sof (firmware/topology) and linux (kernel driver).
   • Kernel: v6.16
   • SOF: v2.13.x
2. Name of the topology file
   • Topology: The kernel requested sof-arl-rt711-l0-rt1316-l3-2ch.tplg, but the working file from the SOF repository was actually sof-mtl-rt722-l0_rt1320-l2.tplg.
3. Name of the platform(s) on which the bug is observed.
   • Platform: HP Omen Transcend 14 (2025) with Intel Core Ultra 7 255H (Arrow Lake)
   • OS: Arch, Garuda, Ubuntu 25.04, Fedora 42. Fix verified in Ubuntu and Fedora.

Looks like this topology is missing in https://github.com/thesofproject/sof-bin/tree/main/v2.13.x/sof-ipc4-tplg-v2.13
@bardliao fyi can the mtl topology above be renamed and reused ?

[bardliao]

@lgirdwood Yes, and PR #10190 added the topologies.

did you ever fix this? i recently put arch on my omen transend and find i have no audio

For me it works by creating symlinks from the ARL topology names to the existing MTL (Meteor Lake) topologies:

# to use the MTL topologies for ARL
cd /lib/firmware/intel/sof-ace-tplg/
sudo ln -s sof-mtl-rt711-l0-rt1316-l3.tplg sof-arl-rt711-l0-rt1316-l3.tplg
sudo ln -s sof-mtl-rt711-l0-rt1316-l3-2ch.tplg sof-arl-rt711-l0-rt1316-l3-2ch.tplg
sudo ln -s sof-mtl-rt711-l0-rt1316-l3-4ch.tplg sof-arl-rt711-l0-rt1316-l3-4ch.tplg

and reboot.

This works because PR #10190 configures ARL to use PLATFORM=mtl, meaning Arrow Lake uses the same topology configuration as Meteor Lake. The actual ARL topology binaries haven't been added to the sof-bin repository yet, so creating these symlinks is the temporary workaround until the next firmware release includes the built topology files.

I tested on my HP omen Transcend 14 (2025) with Intel(R) Core(TM) Ultra 9 285H
