So my SteelSeries siberia v2 broke around a year ago but I just got them fixed. The thing is if I connect both plugs in the rear panel the mic only plays the output sound of my pc but not my voice. But if disconnect the other plug the mic works just fine. I don't know what can be causing it.

My motherboard is the ASUS P8H61 PRO and I'm using Windows 10.
I also tried with another laptop with Windows 7 and the same thing happens.

Thanks in advance.
