Hello, I have a phillips ced 780 head unit. I am running primo 2.4 -9.6.13. My issue is that there is no sound output from the program. Kep presses, tts and non tts voices and alerts all don't work. The music / radio that is playing in the background pauses there is silence then it resumes. It is clear that when it does this primo should be outputting sound but isn't. This is not a build issue as I have currently downloaded 4 different builds and they all have the same issue!

Can anyone help?
Thanks
