Maybe you can take a look at this thread

Asus CX5601 no touch pad, no touch screen, no sound

Hello, I installed windows 11 on this new chrome book. bios Coreboot is installed with version 4.22. I bought the Audio and USB4 drivers from @coolstar and I followed carefully the installation guide. I no longer have any missing drivers. All drivers installed without any error message. Regarding the audio driver, I only have the headphone option in the mixer, no internal speaker. But no sound at all even with an headphone. Any advice on how to solve the 3 problems? Thank you, Jimmy

Hello,
I am having the same issues. The touchpad does not work. I am able to hear sounds from the speakers but not the headphones.
Thanks!
