Headset microphone not showing up in recording devices.

I tried both the methods mentioned, but my external microphone is still undetectable by Windows.

After connecting an external headset with microphone, headset works, but microphone doesn't. Neither the external speaker, nor the external microphone show up in the playback/recording devices list. After plugging in the integrated headset and microphone
through 4 pin 3.5 mm jack, sound comes to headphone, but system still uses the internal microphone.

My external microphone was working fine some days back, but I am not sure what happened that it suddenly stopped working and now is even undetectable.
