Here is some other things I found.
settings- On the Xbox (not Xbox live) go to dashboard settings then to audio and change the setting from Dolby to Dolby Digital with WMA pro.
Xbox live settings-
1. From the Xbox 360 Dashboard, press the Xbox Guide button (the X button in the center of your controller) to access your Xbox Live Settings.
2. Navigate to the “Personal Settings”selection, and press the “A” button on your controller.
3. Select “Voice” from the menu that follows and press “A”.
4. On the “Voice” screen, make sure the “Play Through Both” is selected for the Voice Output selection and that the volume is set to “10”.
