+The MCPX has a PC Speaker pin which can be controlled using [https://wiki.osdev.org/PC_Speaker the standard PC Speaker interface].
 However, no actual speaker is connected to the pin, so while the signal exists, there will be no audible sound on a stock Xbox.

 The original Microsoft code does not drive the PC Speaker at all, so this otherwise unused pin can also be used for inaudible forms of unidirectional communication.
