I recently purchased a Lenovo Ideapad Z500 and realised that it had only one audio jack. I thought that to fix this problem it would be as simple as buying a cheap audio jack splitter to use the microphone on my Steelseries Siberia V2 but I still can't use my headset microphone. I have looked at other posts about similar problems but none seem to make any sense to me. Please help me in any way you can.
