While i appreciate the info, my problem is a little more involved. In the OOB state in which I originally found my computer, the Settings, System, Sound information showed only an AMD microphone array as the microphone input. After updating Adrenalin, that setting showed 'no input found.' Several calls to tech support at MSI and Microsoft lead to the same result - re-image from image partition. Needless to say, 5 times of having to do this to recover the microphone is ridiculous. And it does not solve the problem. MSI support forum help says 'don't update Adrenalin - just use Windows Update.' Ridiculous also. I cannot believe that I am the only one with this problem.
