Certain drivers on Chromebooks have issues. On Lenovo 100e Gen 2, audio is one of them. Two links to fix it.
- Update the kernel to at least 6.19
cd ~/
wget https://chrultrabook.sakamoto.pl/stoneyridge-kernel/linux-image-6.19.0-rc1_6.19.0~rc1-10_amd64.deb
sudo apt install ./linux-image-6.19.0-rc1_6.19.0~rc1-10_amd64.deb
2. Adjust ALSA conf to fix broken paths, etc.
git clone --depth 1 https://github.com/WeirdTreeThing/chromebook-linux-audio
cd chromebook-linux-audio
./setup-audio
