Installation
See Chrome OS devices page.
Text on the screen during initial run (resizing the filing system) is very small and mostly unreadable.
Audio
There are two issues:
- HDMI codec is not supported;
- When booting with inserted headphones, pulseaudio does not switch output to headphones and you have to switch it manually. Consider enabling device and booting pmOS with disconnected headphones as stock bootloader may beep at the maximum volume and you will lose your hearing.
rev4
Audio does not work on rev4 devices yet. You can check board revision with cat /proc/device-tree/compatible.
To start working with ucm you can do strace alsaucm reload to find out where does alsa expect the files to be placed. Files for rev5 can be a good reference: https://gitlab.postmarketos.org/postmarketOS/pmaports/-/tree/master/device/community/device-google-snow/ucm
If you implement it please submit a merge request to pmaports repository.
Modem
Some snow variants have a 3G modem which requires ModemManager:
sudo apk add modemmanager
sudo rc-service modemmanager start
sudo rc-update add modemmanager default
