Description (partial)

Currently the Cisco TelePresence SX80 codec does not support HDMI 1 or 2 audio by default when the HDMI audio for inputs 1 or 2 is enabled, requiring the user to also upon each session either manually enter into the command line admin session (as an example):

xCommand Audio LocalInput AddConnector ConnectorId:1 ConnectorType:HDMI InputId: 4
xCommand Audio LocalInput AddConnector ConnectorId:2 ConnectorType:HDMI InputId: 4

or use TC console to enter these commands for them upon each boot of the codec.  This procedure is also not documented in the SX80 Administrator Guide at

These commands need to be entered every time the SX80 is booted in order for HDMI audio on inputs 1 or 2 to work as expected.  HDMI 3 audio input works by default.
