No audio on QGC

Hey out there in QGC world.
I have an issue with my QGC not providing audio output. I have checked the mute all and that’s not checked. So I am wondering if there operating system requirements that QGC needs to provide the audio. For instance is Text to speech required or some other service implemented on Android 9. I don’t’ believe it’s a hardware issue as I know a few people using the same hardware and it works fine.

Any thoughts would be appreciated.

Solved. I installed the Text to speech engine on Android and rebooted that worked.
I don’t know if QGC uses the engine but installing it solved the problem.
