I got an Lenovo Chromebook s345 and want to install Linux/Ubuntu on it. The problem is no matter which OS i install i cant get the sound / speakers to work and i've tried every tipp/solution i could find on the internet (except black magic..thats a last resort :D ) So i'm currently trying on Ubuntu 18.04 and the last thing i did is a fresh install and installed some packages like inxi and git. I'm a novice to Linux so every idea is welcome ! Here are some outputs:
