<h3>12: Copy audio to UDP</h3>
<h3>13: Audio mute and audio output select</h3>
Copies audio output to UDP. Output is mono S16LE samples regardless of binaural/monaural operation.
Left click on this button to toggle audio mute for this channel.
<h3>13: Audio mute</h3>
Use this button to toggle audio mute for this channel.
If you right click on it a dialog will open to select the audio output device.
