I'm experiencing a different problem than what is referenced in that thread. Couatl is muted entirely. I have to go to the mixer to unmute it. It happens 6 or 8 times during the pushback sequence. This is the only program I have that is doing that. However, I will continue to investigate on my own.
edit: looks like it's just the FSL GSX ACP feature, which I didn't understand how to use
