I have a Logitech Stereo Headset H111 with 1 audio jack (i.e. 3.5mm), and I wanted to use it with my pc, but my pc has 2 audio jack (1 for speaker and 2 for microphone), and when I tried to use it, my microphone was not working. So I buy an audio splitter like this (http://miniimg6.rightinthebox.com/images/190x176/201510/cfvuww1446176922418.jpg) but again my computer showing the microphone is connected but it was not working, So do I need a driver installed in my pc or what should I do other than this... Please help me I am struggling with this problem for 2 months now.
