When you record, or activate Externals, there are meters added to the audio panel which show the level of audio going to those Externals/recordings.

I'd love to be able to see a similar meter for what's going to my vMixCall 1-8 and my Zoom send. This would give me confidence that the right audio feed is being routed to the correct source, and is at the correct level.

What inspired this was a TalkBack button on Streamdeck (which switches the audio send for a specific vMixCall between Master and Bus C) which got stuck so the caller was only hearing the production mic and not the programme. A quick check of the audio metering would have shown me that vMixCall 5 was no longer receiving programme audio.
