I'm having the same issue on LEONA. My issue started after a kernel update. Alsa and friends were updated the next day and it did not fix it. I've re-run the script and it is still not functional.

I'm not sure what type of log would be most helpful, but here's dmesg:

Arch Linux, LEONA

Same problem for me.

Same here. Updated Arch today and broken audio.

Y'all tried re-running the script?

[2DSBrewer]

Yes, or at least I did.

[ninelore]

Just making sure nothing silly on arch side did touch ucm.

Smells like an upstream alsa issue to me

[tails1154]

yea I have no idea what yall are talking about but

1. I did rerun the script, did nothing
2. when I went to do pacman -Syu it complained about some conflicting file, I made a copy of it and deleted it, rebooted. No sound. I put my backup file back there and rebooted. Nothing.

I hope this gets fixed

[tails1154]

(i think) alsa just got a update. I'm updating now

[tails1154]

nope did not fix anything.

Same issue on eldrid with fedora 41

[ninelore]

everyone just downgrade the package for now. refer to your distros docs on how

[slimx]

downgrade alsa-ucm-conf to version 2.12.

[mikaelvz]

I'm on Fedora 41 :

• with latest commit, no sound, there is only the dummy device
• with previous commit (2002c72), I have sound

[WeirdTreeThing]

The issue most of you seem to have is related to the dmic split. I was just able to reproduce this issue myself and found that removing the dmic split fixes it. I'll look into how to properly fix this issue.

@mikaelvz What board name? Must be one where the dmic split isn't needed.

@WeirdTreeThing sorry, forget to mention it, I'm on KLED board

[WeirdTreeThing]

Looks like the fix is to increase the syntax version. Try ./setup-audio --branch syntax-7 and see if that works.

[CoolPenguin27]

I can confirm that using the syntax-7 branch fixed the issue for me.

[tails1154]

let me try that

[tails1154]

yup, running ./setup-audio --branch syntax-7 fixes it for me on CROTA

[mikaelvz]

Using syntax-7 branch also work for me with on KLED, thanks.

[mikezila]

The "branch-7" fix mentioned above did not work for LEONA.

@tails1154 Please don't close the issue just yet. While you may have found a workaround others are still running into the problem.

[WeirdTreeThing]

leona doesnt use the dmic split so it would have a separate issue

[tails1154]

ok I will reopen it I guess

[2DSBrewer]

Yup. On dragonair it works now.

No joy with Arch on SNAPPY.
sudo pacman -Syu upgraded the kernel to 6.12 after I removed the conflicting file similar to @tails1154 mentioned.
I downgraded alsa-ucm-conf to version 2.12.
I reran the script, adding the flag mentioned above: ./setup-audio --branch syntax-7 using the sof option.
I only have dummy output when checking pavucontrol.
I ran the diagnostic script mentioned above: wget https://raw.githubusercontent.com/chrultrabook/linux-tools/main/debugging.sh; bash debugging.sh and added its output. Hoping that the extra info helps troubleshoot. I appreciate the work--it's above my paygrade!

I too have no audio on Arch Linux (Snappy, HP x360 G1)
Kernel version 6.12.4-arch1-1
Did the same steps as mentioned here, only have a dummy audio output with SOF drivers, and no audio interface at all with AVS (with headphones plugged in, as speakers are disabled by default).
Finally got the debug script to run, had to install some packages that I didn't have for some reason.

Thanks in advance

[tails1154]

Snappy seems to have a lot of issues

[dupsneerg]

Snappy seems to have a lot of issues

Yeah, it seems so. I'm running a pretty minimal install, and the only papercut that actually hurts a little is this one. Cheers!

Using syntax7 did not help with CAROLINE board running LMDE. Log files can be found in the issue I created (#208).

[dupsneerg]

There is joy on SNAPPY with Arch!
I executed sudo pacman -Syu and kernel upgraded to 6.12.8-arch1-1.
I pulled in the script anew using git clone https://github.com/WeirdTreeThing/chromebook-linux-audio and ran it with the parameters ./setup-audio --force-avs-install --branch syntax-7 and the audio is working as expected.
I've uploaded an updated log. Thank you so much for the work!

I want to reaffirm what @dupsneerg said about updating the Kernel. In my Pixelbook (also running Arch Linux), apart from this issue, there was a bug in the Kernel which also prevented the audio from working: https://bugzilla.kernel.org/show_bug.cgi?id=219577.

Updating the kernel and re-running the script without any arguments has fixed audio on LEONA.

[SpieringsAE]

running ./setup-audio --branch syntax-7 fixes the issue on DRATINI running arch, nice!

[ShawHaines]

Had the same issue and ./setup-audio --branch syntax-7 fixes it for me.

[imthatleon]

Using syntax-7 on Reef does not work with Kernel 6.12.x

[cameronj86]

./setup-audio --branch syntax-7 worked for ELDRID running kernel 6.12.9 Debian Trixie

[WeirdTreeThing]

I've merged syntax-7 into the main ucm branch, so this is no longer required. If syntax 7 breaks anything for you, you can use the old-syntax branch instead.
