I've had my 9285 for about a year now and everything usually works great. Recently I installed then uninstalled Connectify (Turns my laptop into a WiFi hotspot). Now my headphones don't work. I've tried 2 sets with the same result. The speakers work fine. I've uninstalled then re-installed the Realtek drivers/app. When I plug them in, I get a notification that I have plugged something in to the headphone jack. And that I've unplugged something when I unplug them. If I have the Audio Manager open when I plug them in I see that the "Headphone Virtualization" checkbox becomes active. So it's recognizing that there are headphones plugged in.
Why would the speakers work and the headphones don't?
