No sound with INTEL Comet Lake PCH cAVS and current kernel
Closed, ResolvedPublic



on a fresh install i have no sound at all (and no microphone) with Intel Comet Lake PCH cAVS on a lenovo X1 extreme Gen 3 core I5 and GPU and audio Intel with current kernel 5.10.1-162. The audio card is not detected but it is well indicated with lspci command : 00:1f.3 Multimedia audio controller: Intel Corporation Comet Lake PCH cAVS

dmesg errors :
[ 1.875686] sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cml.ri failed with error -2
[ 1.875688] sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cml.ri failed err: -2
[ 1.875689] sof-audio-pci 0000:00:1f.3: error: failed to load DSP firmware -2
[ 1.881811] sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -2

That is a regression because all is ok with the default kernel on Solus 4.1 downloaded on the website (5.4 kernel version).

Thanks for your help

Is this still an issue with the latest kernel and alsa? We've updated alsa-lib, alsa-firmware, and linux-current since then.

Still an issue for me

I thought I would post this here given that the other issues are closed.

Intel Comet Lake.

I just did a new install of Solus Budgie and installed sof-firmware and no luck.

Followed the old procedure and installed the v1.9 driver from and they worked.

No clue why or why not.

Just a follow up.

sof-firmware installs sof and sof-tplg to the /lib/firmware folder. I believe that the correct folder is /lib/firware/intel. I cut and pasted the sof and sof-tplg folders into /lib/firmware/intel as a quick check and now the sound works. I haven't bothered with symbolic links or whatever.

P.S. Solus Gnome this time.

@riffer: Interesting. Seems like during the initial inclusion that folder was changed, when it was updated to version 1.7 (between and
But the instructions upstream clearly state [...]/firmware/intel/

Maybe an accident that has been propagated until now? Which is strange because I thought I saw people remark that the package worked.

@TClark77 Could you maybe take a look at this? I don't know if you have hardware to test this yourself, but I'm sure @riffer could help out.

I'll take a look at this in the next few days. My laptop does have an Intel audio device. I don't have any errors but I can look at the folder issue.

If it helps, this is what I do to get the driver's work (Sorry for the "sof for dummies" instructions, but I document everything I do and once it works I stick with it. I don't have enough knowledge to optimize).

Add rsync from software

sudo nautilus remove any sof files from /lib/firmware/intel/ maybe /usr/local/bin/sof-* as well?

		press latest release, go to bottom, download tarball
		sudo nautilus
		create directory /usr/local/bin

terminal Go into v1.9.x directory

		sudo rsync -a sof*v1.9   /lib/firmware/intel/
		sudo ln -s sof-v1.9      /lib/firmware/intel/sof
		sudo ln -s sof-tplg-v1.9 /lib/firmware/intel/sof-tplg
		sudo rsync tools-v1.9/*  /usr/local/bin
		reboot, turn up system sound

I end up with the following files:

I'd be willing to test any changes.

@Staudey , @livingsilver94
After looking at the at, the upstream maintainers recommend moving certain files leftover from installations < 1.7 to a backup directory. Has Solus done this kind of thing in the past, and if so, what's a recommended directory path? It looks like the cp commands in the package.yml should be replaced with mv. We should also clean up files that were installed incorrectly to the wrong directory. After this is decided it should be easy enough to change the install directory to the correct place.

I think for now it would be fine to simply change the corresponding parts of our package script to

install -dm00755 $installdir/lib/firmware/intel
cp -a sof-v$version "$installdir/lib/firmware/intel/sof"
cp -a sof-tplg-v$version "$installdir/lib/firmware/intel/sof-tplg"

i.e. with the /lib/firmware/intel path, instead of simply /lib/firmware

@darkben The change that should hopefully fix the issue you were seeing has merged. Would you be able to test it out? Let us know if you still see issues.
