Mic not working - Windows 10/Realtek

[Dijita]

Is anyone having difficulty getting a mic to work on Windows 10? I just got a new Alienware X51 and it came with Windows 10. It has the microphone, line-in, and line-out jacks (pink/blue/green) on the back of the desktop, plus the input and output jack on the front. The only one that I can get any kind of sound out of, is the output jack on the front. No matter which jack I plug my headset (3.5mm) into, my computer won't recognize the mic.

I have tried downloading all the updated drivers from Alienware. I have also tried uninstalling and reinstalling the Realtek High Definition Audio driver several times without success.

Your Webcam's Mic will be default.
You need to set the FP or whatever analog Mic as default if u wish to use that instead.
Under Playback/Recording Devices.
Also, I would first go to Realtek website and install latest "HD Audio Driver" from Downloads.

There is only one Analog Mic jack, be sure it gets plugged into correct one.

Having the same issue and while the webcam (USB) mic is working just find, no amount of tweaking can get the analog input mic to work. I've tested the headset on another system and verified it works. One thing I do notice is that, if I call up "playback devices" from the audio icon in the bottom right hand of the taskbar, I can watch the mic volume momentarily spike as I plug and unplug it. I also get a message that "Realtek" detected it...
