Sorry, close this thread. I realized I had the USB cord plugged in in the wrong spot.
I use an A/V cable so it's not HDMI. I got my X11s today and set them up exactly how it says to. On the amplifier the LED light is white, not active nor muted. My friends can't hear anything I say, and I can't hear them. I have Game and Chat at full blast on amplifier and XBOX settings. I also can't hear game sounds. WTF.
