Please help me, I know how to configure stuffs on my laptop's recording devices. Normally, it should automatically detect the headset and mic but not on this device. Laptop still uses the built-in microphone instead of the headset's mic; and when mic is turned to 'mute', the voice/sounds being recorded become annoyingly terrible. Headset's jack is only one, and has three lines on it. It supposedly should work well on laptop but why am I experiencing this? Please help. Thank you very much.
