How does the S/PDIF Port work? If it can be used with RCA Adapter, how would I connect the cables from the VGA HD AV cable?

S/PDIF stands for Sony/Philips Digital Interface Format and carries audio data over either an optical (TOSLINK) or an electrical (coaxial) cable.

The Xbox 360 uses TOSLINK cables for its S/PDIF interface. TOSLINK ports are covered by a plastic door - usually black - which is meant to protect from dirt.

Plugging a TOSLINK cable in a TOSLINK port is as easy as plugging a USB cable in a USB port, since the plastic cover does not hinder the cable from reaching the port.

When powered, a TOSLINK port will emit red light, which can be visible through the black plastic cover.
