External microphone not detected, tried everything

Hello, i'm using a Siberia V2 headset. Here is my laptop : Asus ROG G741JM-T4065H

I'm using this splitter : Amazon.com: StarTech.com Headset adapter for headsets with separate headphone / microphone plugs - 3.5mm 4 position to 2x 3 position 3.5mm M/F: Electronics

My headset is in the soundtab, but no microphone (except the internal one) is the recordtab :


My headset works fine with a windows 7.

Are you sure the Tip/Ring/Ring/Sleeve is what is used on your PC? Many with one jack are standard Tip/Ring/Sleeve and are a combo jack - can be used for either mic or headset but not both.

I just researched two other ASUS laptops and that is the way they are - jack that can be used for either but not both.

I'm pretty sure, because when i plug only my headset (green jack) without the splitter, it works, but sitll doesn't work when I plug the pink one alone.

I've tried without success to get a 4-pole headset to work with my Asus laptop which has the single audio combo jack. The only external mic I was able to get to work had a stereo 3.5mm plug.
So I'm thinking unless you use a break-out adapter it's either/or...mic or headphones. I've read lots of threads and I don't see anyone having luck with a 4-pole headset.
