I have a Samsung Chromebook Pro (Caroline) running Fedora. After updating, I lost the audio. I have tried rerunning the script and also tried using KDE, but it did not work. I have posted under issues on the WeirdTreeThing GitHub Chromebook-Linux-Audio page and have received no response. Is that not the proper place to post? I don’t want to nag, but it’s frustrating not to have audio. Any assistance or guidance would be greatly appreciated. Thank you!
Please provide debug logs like requested in the docs

Also if you run sudo dnf update it will cause the same problem, and I have fedora 40
So if I run this I have the same problem.
sudo dnf update - kernel
sudo dnf update - kernel-modules
sudo dnf update - kernel-modules-extra
Hi,
A have the same problem with a Asus Chromebook Flip SHYVANA, that use the same audio chip max98357a.
To be sure, I reinstall to Fedora 39 and apply the WeirdTreeThing script. And everything works.
I don’t know if it’s the same I see in the Setting pannel, Headphones (under latest 40) and not Speaker (as before).
I will update step by step to see when it breaks.
I found it! It’s this command that’s taking away the audio
sudo dnf update kernel-modules-extra

Please attach the output of: Debugging | Chrultrabook Docs
How to add the debugging output.
Same conclusion the kernel update.
- Download our debugging script.
cd ~/Desktop;wget https://raw.githubusercontent.com/chrultrabook/linux-tools/main/debugging.shIt will dump:
- ACPI tables from sysfs (
/sys/firmware/acpi/*)- DMI information (
dmidecode)- Coreboot buffer (
cbmem)- Linux kernel logs (
dmesg)- List of PCI devices (
lspci)- List of USB devices (
lsusb)- Information about soundcards present in the system and their configuration
Into
debug-logs.tar.gzarchive on your desktop.
- Run it:
chmod +x debugging.sh;./debugging.sh- Upload this file if you need help with troubleshooting.
- Remember to remove WiFi information from dmesg to protect your privacy.
I know but how to upload them here?
You can use haste/pastebin or external temporary file hosting (like uguu.se)

But I did have to change the volume of the mic in alsamixer.
So the only thing that does not work is the onboard headphone jack, but a USB-C to 3.5mm audio jack works just fine.
