While I am able to see the text communications with ATC, I am not able to hear any voice communication between PF3 and MSFS 2020.
1. I am running the latest PF3 3.10.0.
2. I have installed the DirectX Runtimes as suggested in the FAQ
3. I made sure that SOUNDS, Communications tab is set to DO NOTHING. I have also toggled between these settings and applied just in case.
4. When I check voices inside PF3 to choose the pilot voice, I can hear it without issue.
NOTE: While I am NOT using MCE during the above tests, I do want to mention I did try MCE with PF3 and MSFS 2020. When I did do this, MCE voices come through without issue. Also, MSFS 2020 ATC voices come through without issue.
I also set PF3 to hear a sound when a PF3 compatible key is pressed and I do hear a system sound.
PF3 does display the interaction between PF3 and ATC correctly when pressing the appropriate keys.
I simply cannot hear any voice from PF3 or from ATC.
