Making some changes in our system with the microphone output (adding VB-Audio Virtual Cable on the system) , will be posting related vMix config questions in a new thread later.

We have Settings | Audio Outputs | Master Output set to None, do not need to monitor the audio (I use NDI on another computer to check when audio needed or check the live stream).

If Master Output is always enabled, why is there even an Enabled option for it? What does that do?

I understand for Bus A/B, you can use Enabled so the Bus can be used in NDI, streaming etc and don't need to send it Out, but it's not clear why that option is available for Master Output.
