The built-in mic on my T100 has, at some point, stopped working. I only noticed today. I have Win 10 installed. I have uninstalled and reinstalled the mic drivers, installed new drivers from the asus website, installed realtek drivers, all to no avail. In device manager it shows "Intel SST Audio Device (WDM)" as the only installed mic, and in device properties, it says the device is working. Under windows sounds, the built-in mic is set as default. However, it just isn't picking up any audio! What else can I try?
