[TriEmbed] Raspberry Pi 2 rocks...

[Carl Nobile]

Kyle,

Off the cuff I would say any stereo cable would work. Like an extension
headphone cable. All audio connectors of this type have a at least  a tip,
rings and sleeve. The sleeve is always the ground and the other would be
left and right channels. In the case of an RPi the tip is the microphone
and the ring is video and the sleeve is the ground for both.
