I have added new callsigns to EVP and also set the speed to 30% increase. Just the way I have done it over the past 10 years.
In P3Dv4, I can now hear *some* voices accelerated and using the new callsigns. However, some other voices remained on default, speak at default speed, and do not pronounce the new callsigns.
How can I solve that problem? I have read somewhere that AIG AI Manager would be the culprit. But what *exactly* do I need to do there? In AIG AI Manager I have uninstalled OCI, and in the OCI settings I have un-checked the “Use ATC file” box. I have started EVP again after that and recreated a sound file.
However, the problem persists. Anything else I can do or check?
I would try restoring the original Flight Simulator files:
Once they are restored, run EditVoicepack again and let it accelerate the files.
If the problem comes back, it is either something like AIG AI Manager (I do unfortunately not know the details on how to set it up to avoid this), or something else restoring the original FS files (for example a Steam repair would do this).
