@ecrowell the "mute original speaker" function does exactly what you described. If the person LISTENING to the interpretation selects the option "mute original speaker" then he will not hear the main/original speaker NO MATTER who is speaking. The listener will only hear the Interpreter on the language channel that the Interpreter is speaking on.
This setting is not effected by the channel that the main speaker is on.
My suggestion is that no one uses this option, as it gets users/attendees/listeners confused!
Interpretation = live translation by people for people
We specialise in organising and running events with interpretation.
