Separate audio and video output on Xbox 360 E
To split audio on the Xbox 360 E, you will need to use the included 1/8" AV Cable and connect this to your receiver. Be aware that splitting the audio and video signals from the 360 E in this manner does not support Surround Sound audio. If you are encountering dropped signals or missing audio, make sure that your Xbox 360 audio settings are set to Stereo output. If none of the above steps worked, we would advise you to get in touch with the Xbox support teams, who are better equipped to understand and troubleshoot this situation.
