Answer to: How do I get rid of feedback buzzing/beeping?Very high volume settings may cause noise from the speakers to be picked up by the microphone. This creates a sound loop that gets louder and louder until you disconnect the headset. As such, you should lower the volume of your headset by pressing the "volume down" button on the adapter. Another source of the problem may come from someone else in your Xbox Live chat room. that person may be having feedback problems and is transmitting those sounds to all the people in the chat room. You should be able to see which person in the chat is transmitting the feedback; ask that person to lower the volume or unplug his or her microphone. If you are still not sure what is causing the feedback, check out the troubleshooting page.
Answer to: Why won't the microphone pick up sound?Have you checked to see if the mute function is activated? Make sure that the microphone is not muted by pressing the mute button on the adapter. It's also possible that the headset is not completely connected to the adapter, or the adapter may not be fully connected to the controller. In this case, the speakers would not be working as well. If these suggestions did not solve the problem, check out the troubleshooting page.
