I have a JBL Quantum 100 which said in the manual that if I have seperate headphone and microphone audio ports to get my own splitter, which I did, yet the microphone is not picking anything up, no sound whatsoever. I checked devices and it does detect a microphone with the Realtek audio driver, yet no audio is coming from it even when the mic is plugged in on the headset. I would appreciate some help fixing it. I got it not too long ago.
