Disable or enable audio and output port volume

If you're displaying a channel as the source for your video output port, audio for that channel is also encoded and sent over the port by default. You can disable the audio on the output port using the Admin panel. You can also adjust the volume of the audio on the video output port using the Admin panel. Disabling the audio on the video output port improves latency for the port.

If you're displaying a video input as the source for your video output port, you can select an audio source and adjust the volume. Audio is taken from the video input source you've selected for the video output port by default.
