Headset microphone doesn't work Dell Latitude 3340
Recently I bought a headset, so I can chat with friends while I am playing games with them, but it doesn't work as I want it to. It has 2 3.5mm male jacks (one for headphones, one for microphone) while my laptop has only 1 female jack. No problem, I bought a microphone and headphone splitter. But my laptop cant recognize my headset as a headset. It only shows headphones, or microphone. I can't use them combined! So if I try to speak the sound comes from my internal microphone in my laptop but not from my headset, and the sound comes from my headphones. And exactly the other way around: if I can speak through my microphone, the sound doesn't come in my headphones but from the internal speakers in my laptop. How can I fix this? Thanks!
