Audio Input HDMI [1] Mode
If you are connecting a Cisco camera with an integrated microphone to the codec's HDMI 1
input, you can enable/disable audio input on the port; if you are using any other camera, the
audio input will be disabled regardless of this setting.
If you are going to use the integrated microphone, this setting must be On (default value).
Whenever you are connecting a Cisco Table Microphone 20 to any of the codec's external
microphone inputs, the integrated microphone will be disabled regardless of this setting.
