Good day. We are using HP Notebook – HP EliteBook x360 1040 G7. It seems that on linux (any os – we tested on ubuntu, centos and some others), even on latest kernel, inner microphone does not work, the fingerprint sensor does not work and there some problems with functionality buttons (brightness adjustment, for example). It seems than problem is known among some notebooks (there is info on forums). And there is no solution. On windows there is no such problems. Maybe there is necessity to include some other drivers in kernel? or there are other solutions?
