I don't often use the built-in microphone on my ASUS ZenBook Flip 15 (Model: ZenBook UX564EI_Q538EI), but when I needed it, I found that it was no longer part of my system. I checked the Device Manager to see if a driver needed to be updated, but the device is no longer listed. ASUS could not load the device driver.
Any tips on how to fix this issue?
