• The analog audio can be assigned to a specific input or set to be always output
(see Assign analog audio SIS commands on page 22).
By default, audio input is selected automatically (see Assign analog audio SIS
commands on page 22 to manually select audio inputs). When the HDMI input is
selected with automatic audio input selection, the transmitter prioritizes embedded
digital audio. The following table shows the audio format that is sent over the DTP
connection when a specific audio format is not specified.
