6.7.2. Non-priority (first detect)
After the video Autoselect the device checks the embedded audio input. (DVI-D
embedded audio input to the DVI-D video input or HDMI embedded audio input to the
HDMI video input) If there is a valid embedded audio signal it will be selected. If there is
no valid embedded audio signal the device checks the S/PDIF audio input. If there is a
valid S/PDIF audio signal on the S/PDIF audio input it will be selected. If there is no valid
audio signal on the S/PDIF input the device selects the analog audio 2 input, even if there
is no audio signal on this input. If there is an event (any audio is plugged or unplugged)
the device checks the selected audio input port. If there is valid audio signal on this input
port it remains the active input port. If there is no audio on the selected port the searching
process starts again. The selected audio input will be active until a new result of video
Autoselect or the device exits from the Autoselect mode.
