USB Microphone not working with Windows IOT Core

I tried both the November 2015 release (build 10586) and the Feb 2016 Insider Preview release (build 14262), however my USB microphone is not working with Windows 10 IOT core.

Scenario:

I am creating a speech recognition based program using windows IOT Core.

I am using Windows.Media.SpeechRecognition api for this job. When I run the program on a simulator in my Window 10 PC using Visual Studio 2015, microphone works and sound gets detected and the program functions as required.

However when i deploy the same build to my Raspberry Pi2, which has Window IOT Core installed, program doesnt detect any sound. I see that my microphone is detected correctly by Windows IOT Core, as i can see the same in the default app which comes with Windows IOT core.

I can listen the sounds (headphone) though. However somehow my microphone voice is not getting through to my speech recognition program when it runs on RPi2 with Windows 10 IOT Core.

Steps to reproduce:

Create a speech recognition program using Windows.Media.SpeechRecognition api.
Check the program functioning on Windows 10 pc in a simulator
Deploy the same build to RPi2 with Windows 10 IOT core.
Program doesnt detect any sound from microphone.

Need serious help.

That's because\n\nWindows.Media.SpeechRecognition.SpeechRecognizer does not support now.\n\nyou can check here\nhttps://developer.microsoft.com/en-us/windows/iot/docs/UnavailableApis.htm",
