I just found https://superuser.com/questions/1719920/no-sound-from-internal-speakers-on-laptop-but-headphone-jack-and-hdmi-works with the link https://gist.github.com/lamperez/862763881c0e1c812392b5574727f6ff

It sounds very much like this problem right here. Can we build a workaround for our machines? Extracting the respective data from Windows and injecting it into our Linux istallations?
