Audio Mixer & Audio Record/Returns

[skillet]

1) I am wondering if the "Audio Mixer" from the global Audio menu is the same as the Audio Window, Options:Audio Record/Returns.

 

2) As far as I can tell they both want to open up a layer with an audio object. I can't seem to find a pattern of how it chooses what layer to open. I have put multiple audio objects in different layers and it doesn't seem to choose one based on the most audio objects, or the layer that has Track 1, or the one that is on the in the lowest or highest layer.

 

I have noticed that you have to close the Environment each time to refresh it though. Anybody know how it chooses what layer to go to (other than the fact that it has to have an audio object)?
