Fixing audio and keymaps in Chromebook Running Debian Bookworm

I recently bought an HP Chromebook from Abhas who had already flashed coreboot in it. I ran a fresh installation of Debian 12 (Bookworm) on it with KDE Plasma.

Right after installation, the Wi-Fi and bluetooth were working, but I was facing two issues:

• Playing a music file or any audio file does not give any audio.

• Keyboard buttons like the ones for brightness and audio adjustment were not working (alphabet keys were working).

Fixing audio

I ran the script mentioned here and that fixed the audio.

The instructions from that link are:

git clone https://github.com/WeirdTreeThing/chromebook-linux-audio
cd chromebook-linux-audio
./setup-audio

Fixing keyboard

To fix the keyboard, go to KDE Settings and in the Hardware section, under the “Keyboard model” box select the option Google | Chromebook as depicted in the screenshot below.

I hope this post fixed the issues for you. Meet you in the next post.
