well first of all this is a question for the AV forum...
TOPIC MOVED...
next the answer to your question is in the sticky:
QUOTE
What A/V cables will be included with the Xbox360?
The Premium Xbox360 package will come with a single A/V adapter that includes both composite and component output, as well as stereo RCA output. It also has a socket in the connector for a digital toslink audio output for surround sound.
The Core Xbox360 package will come with a standard composite A/V adapter with stereo RCA outputs for audio. It is unknown whether or not this cable will include the toslink socket for digital audio (though I personally think that it is unlikely).

If you didn't know composite is the single yellow wire, and stereo RCA is your white/red audio...
