This seems like something simple but I can't figure out where to find the help...
Have an Alienware M17xR4 with Sound Blaster Recon 3Di. Suddenly today, when I plugged in my microphone, it now appears on the "JACK SETUP" box that I am plugging into a "Rear Speakers" port. My other two side ports are still headphones, but now I can't find my microphone! Further, the internal microphone seems to be disabled or otherwise not working. The S/P DIF port is now suddenly internally illuminated in red ever so slightly. I'm assuming something has turned on that I didn't intend, but I have no clue how or how to correct. Any assistance would be appreciated as this has been bothering me for hours.
Note that this seems to have "happened" during a simple reboot of the system. OS Windows 7 Professional.
