NOTES:
•
Selects between analog (3.5 mm TRS) or digital (embedded in HDMI input) audio sources.
•
Inputs 1 and 2 X3$ can only be set to 0, 1, 2, or 3; attempting to set these inputs to a digital format yields an E14 response
•
Digital auto modes (6 or 7) detect and use embedded audio when present, or use TRS 3 if digital audio is not detected
