Cannot get any sound from headsets

A lot of folk have had problems using the X12`s.

Using an xbox audio adapter WILL cure the problem as the audio signal is direct from the console to the headset. The HDMI is purely used for the video signal with that particular setup.

I have the wired X12's not sure if theres a wireless version but when I hooked it up I putt the red and white in the Tv, and plugged the green in then lastly I connected my chat part to the controller. They work great. I found out that turning your tv down
to mute volume helps reduce the static from the Mic part if you all get any.

I have bought a Xbox 360 audio adaptor cable to see if that sorts it out.

If you are using the AV cables it shouldn't be a problem without an audio adapter. I haven't attempted to use the HDMI cable + audio adapter combo because I never bought it. Your problem might be in the way you have it going to your TV. My suggestion would
be to use your AV cables and give it a shot. Also, it doesn't require you to use the headphones setting so take that off also try messing with the little adjuster box on the headset wire. it has options for gaming and chat volume plus the ability to mute your
mic.

I've never understood why they put that plastic piece on the A/V cables in the first place. My only thoughts are that they do it so they can sell you another accessory.
