No voice from QGC v4.3.0

I need some help from this forum. I’ve been using QGC for 7 years and it has always had voice responses to RC inputs and error messages. Suddenly this week there is no voice at all. Very strange. Maybe he’s on vacation, or got a cold and lost his voice. Maybe he’s on strike. The silence is deafening.

Has anyone else experienced this issue? What is the solution?


And it’s not the setting “Mute Audio”? Is this on a new install? macOS, Windows, Linux?
