Audio Input Type
Media Audio Input
When the Endpoint is connected to both a microphone and other media audio inputs (such as connected
to a computer to play audio), you need to configure the type of media audio input, so that the mix input can
be realized. The sound from the media audio input device is mixed to the local output by default and can be
mixed to the remote output. This feature is not applicable to VP59.
Note: If the microphone is connected to the device via Line Input or USB to Line Input, you should
not select the interface to which the microphone is connected when using the media audio input,
otherwise there may be a strident sound.
