Hi, First of all thank you so much for this incredible work. It has completely transform my old 2-in-1 into something of a joy to use. Some issues that I hope you could help with

No wifi on any kernel other than 4.19.
Sound card is detected and sound works via Bluetooth speaker but not internal one
Camera doesn't work
Brightness control doesn't work

This is the component of the device: https://www.driveridentifier.com/scan/samsung-galaxy-book-12-lte-driver/desktop/AE512B24EF7440AFBADC0C3B76C1F896

I tried rammus & nautilus recovery images, as well as all the options available in the settings (no camera fix, oled screen,..).

I'm on brunch 93 and chrome OS 93.

Honestly, I hesitated to buy this device a few years ago but decided not to after seeing the linux compatibility reports.

I don't see any success story with brightness on linux with this device, only xrandr software brightness workarounds which will not work on ChromeOS. I am not sure if the camera works in linux but in any case it would not work in ChromeOS as it does not support i2c cameras.

I think for sound you will need the kernel 5.10, I will try to fix wifi in kernel 5.10.

thank you for such a quick reply. The brightness issue can be fixed with a screen filter app from google play. Not perfect but it works for me. I don't use the camera much anyway so that's something I can live with. If the sound can be fixed it'll work very well as a daily driver. Looking forward to that!

Try kernel 5.10 with this build: https://github.com/sebanc/brunch-unstable/releases/tag/r94-unstable-20211107

Wifi works with kernel 5.10 & r94 unstable. Still no sound from the internal speaker though. It does recognize the sound card, however no sound coming out.

Could you post a dmesg ? (run "dmesg > ~/Downloads/dmesg.txt" in crosh shell and attach dmesg.txt from your Downloads folder)

Then, boot with "module_blacklist=snd_hda_intel" added on the kernel command line, test sound and post another dmesg.
