CHUWI GemiBook 13

Does any audio device show up in Windows device manager? Tried hwinfo64? On Linux you can try to run “hardinfo” (sudo apt get hardinfo, on deb based) to get a thorough overview of all the hardware in your machine. These should at least reveal the hardware id of the sound device, which you can use to find the make and model.

Here’a a thread all about this issue and possible solutions. Chuwi Gemibook Drivers
