Garry's Mod - No Third Party Weapon Sounds

Video:

Of course we use the same weapons. I can’t hear my own weapon sounds (I can hear official HL2 Weapon’s Sounds) but the one from others.

Weapon used:
TFA CS:GO MP7

EDIT: I do NOT have any Pirated Content. I just have CS:S Installed and of course mounted(I have it purchased on Steam). I am not experiencing HUD Issues like other people. It’s just the Sound of Third Party Weapons like TFA; FA:S; M9K, etc…

It’s going to either be on you, the server or the addon creator. Either the server doesn’t have workshop dl/fastdl setup, you have downloads disabled or the addon creator didn’t include the sounds.
