I just bought a brand new Bose QuietComfort 15 headset, and it comes with only one cord for both audio and microphone. My asus laptop only has one audio/mic combo jack. When I plug my headset into the jack the microphone doesn't pick up sound or even show that it is present. The only mic that is shown is the internal laptop mic. I have checked every physical attribute and nothing is wrong or off. If anyone knows how to fix this please help!
