When creating or viewing a configuration, you must specify whether the

7* I/O button — The I/O button selects video, audio, or video and audio for
input selection.
8* Video and Audio LEDs — The Video and Audio LEDs indicate whether
video, audio, or video and audio will be selected using the Input and output
buttons (

Pressing the I/O button advances through a cycle of video and/or audio
selection as follows: {default} video and audio, {press} video only, {press}
audio only, {press} video and audio, and so on (figure 3-2).
