Make sure audio is properly plugged in. If you don't have a headphone/microphone jack in one then buy a Pcie or pci card for it.

i believe the phones in question are designed for smartphone usage and not a gaming headset. the cable allows you to listen to audio from devices that are not blue tooth compatible. I might be wrong but I could not see the cable in question.
