Assetto Corsa SFX (Assetto Corsa)

Hi all
who can I send the original files from the SFX folder (Steam\steamapps\common\assettocorsa\content\sfx)
I put the sound fix and now I have almost all of the original machines without sound (probably something I messed up there), and mods I have a lot to reinstall the game.
here's an e-mail

thanks in advance
