Yeah, when the client was developed, it was developed essentially for pilots. And nearly all of our pilots use microphones/headsets. I can’t speak for the developer, but I assume perhaps the thought of people thinking about using vPilot for Observer-only connections either came later, or was/is low priority compared to ease of use for pilots who want to use a microphone/headset.
I know @887155 you’re working other priorities these days, but I wonder if “can use vpilot without a microphone device” is on at least a “maybe in the future” list?
In terms of speaker vs. headset, yep, that’s exactly how I have my own setup configured. Sim to speakers is set up in the sim, and ATC to headset is set up in vPilot settings.
