Hi I’ve installed endeavour os gnome on a lunarlake lenovo yoga slim 7i. It seems like the audio is not working. If I do inxi -A
Audio: Device-1: Intel Lunar Lake-M HD Audio driver: sof-audio-pci-intel-lnl API: ALSA v: k6.13.7-arch1-1 status: kernel-api Server-1: PipeWire v: 1.4.1 status: active
This shows up. Any solutions?

I also tried installing linux-firmware-git and lts and zen and mainline kernels, but the audio is not working with either. (mainline breaks wifi even) (also, bluetooth is not working on any of them)

@Sboykorea have you made any progress in the last days? Appreciate any hints, thank you!

Seems to be a general issue on Arch currently, according to this.

There is also an thread on the Arch Linux forum which might be worth following.

You could try to install alsa-lib, which is an alternative to the regular alsa implementation and includes the ALSA Use Case Manager configuration (and topologies) as a dependency which seems to have fixed the audio issues, at least on the 15" variant of the Yoga Slim 7 (15ILL9), according to this resolved issue over on github.

Hi @1093i3511 , thanks for your research, I didn’t look into the sof project repo, but that is exactly where the suggested fix you found worked for me. <3

In short, yay -Syu linux-firmware-git alsa-ucm-conf-git should solve the problem.

To skip building linux-firmware-git locally, I also included garuda’s chaotic aur as the lowest priority pacman source.
