I am unable to get sound from PF3 during an actual flight. I have the (ancient) DirectX9 module installed as referenced in the FAQ. When selecting voices from the options menu I can hear the "radar services terminated..." sample correctly from each voice, but I get nothing when PF3 is running with my sim.
I'm running the latest version (including the update that it found after downloading the full version). My sim is Prepar3D v3.4 (latest update).
I'm sure it's me doing something wrong, but I don't know what!
