Query: Head phones work fine but microphone doesn't work

The splitter works fine for the head-phones but couldn't get the microphone to work. It seems to be some contact issue with the splitter and the socket on my laptop. If I pull it out a tiny bit and hold it, I can get it to work faintly. Otherwise, there's no microphone function. I wish I had a solution for this. This one turned out to be useless.
