Carrefully QGC does not work if audio jack is not plugged !

I found this too. If there is no audio output device on my laptop (eg if speakers are disabled and no bluetooth headphones connected) QGC won’t open. As soon as I enable the speakers or connect my headphones it opens correctly. I’m guessing that’s what the OP means in regards to audio jack?
