Here's the fix for the "Can't recieve sound on line ##########" guys!:
You download and put Steam Fix in your PacSteam, GreenLuma or cracked Steam directory.
You go to C:\WINDOWS\system32\drivers\etc\host and open it with notepad. Add this 2 lines:
You open steam FROM THE "STEAM FIX.exe" (you could make a shortcut in desktop, because you have to launch steam from there after this), you open Garry's Mod and you connect to a server from here: http://css.setti.info/servers/garrysmod/ (CarbonicServers always works for me and it's cool.
