Apocalypse

Hello, I have a sound issue on Jagged Alliance Back in Action. When i launch the game I perfectly hear sounds from intros videos. But then, when I arrive on the main menu, no more sound at all. Same thing while in game : zero sound, i can't hear nothing, no shoot fired, no step, no vocals, no music : nothing. Of course I checked the audio option in game, and they are all maxed. I tried to reinstall my audio drivers but it does not fix the issue, then again, the sound in all the other games I have works perfectly. Also, I try to verify JABIA cache files from steam parameters. It doesnt fix the sound issue. Any Idea, any help would be welcomed !
