CSS Sounds not working.

I have counterstike content ingame, but theres no css sounds.
In DarkRp I can buy guns etc but theres no css sounds and I can’t aim through the sites, and some servers you have to aim to shoot. I can hear all hl2 sounds etc. If I shoot, I can hear the bullet hit the wall but I can’t hear the gun fire.

I used gcf scape to extract the sounds folder from css, but I have no where to put it in gmod folder.

Make sure the CSS content is mounted in GMod.
