I just bought a new Razer headset after using a USB headset for quite some time and I've unfortunately discovered that my audio/microphone ports on the back of the motherboard don't detect anything. I've tried with 2 other pairs of headphones now and it picks up nothing. I've updated the Realtek audio drivers and that hasn't seemed to fix anything either. Is there some cable I haven't plugged into the motherboard possibly, or will I need to RMA? If it's not too late?
