Failed to load sound

Ok, this time i succeeded to get something instead of nothing when using sound.play with custom sounds.

But i don’t hear anything i just got spamm in console saying that when locking a car :
Failed to load sound “realistic_rp\carlock.wav”, file probably missing from disk/repository
And that when unlocking a car :
Failed to load sound “realistic_rp\carunlock.wav”, file probably missing from disk/repository

Does the client have that sound file in that exact directory?

The sounds are in
common\GarrysMod\garrysmod\addons\realisticroleplay_content\sound\realistic_rp\carlock.mp3
common\GarrysMod\garrysmod\addons\realisticroleplay_content\sound\realistic_rp\carunlock.mp3

EDIT :
I made a mistake, it was .mp3 not .wav sorry i was wrong. Now it’s working, so yay !
