I have had success overriding textures, campaigns etc., however I seem to be unable to override the files in sound\chat\
Specifically I have created 22khz mono 16bit samples to override 952a.wav, 954a.wav and 955a.wav in a custom pk3 file on the server. The clients connect, download, and show the files are pure in their console.
However the corresponding voicechats (ftgoundercover, ftprovidesnipercover, ftchecklandmines) still play the original sounds.
I have tried overriding “standard” voicechats (e.g. 10a, enemy in disguise) with the same lack of success.
Thanks for your help!
