I’d like to second this.
Like OP said, a on/off commutator would do the trick.
There are multiple things I’m thinking of :
- Linked : Prevent passengers talking at the same time as ATC.
- BONUS : Can we get a new “soundcard binding”, so that I can move passenger sound on an other (virtual) sound card ?
- I filled a wishlist for that part
- BONUS : Maybe that commutator could be “Passengers are talking on the COMM3 radio”, and we can then turn them on and off directly in the cockpit ?
Cheers,
K.
