OK so all changes completed with one difference.
I made the cvar cg_ambientSounds (no biggie)
Here is what I noticed its not dynamic. it scared me at first cause I loaded up the game and I changed it an nothing happened. So I though "aw crap what did I miss?". (I studied what you did in the code since you posted it. Just trying to get a sense of what was happening and making sure I understood what was going on.)
Well of course I alt-entered to look at the notepad++ screen to see and that's when I noticed... HEY IT CHANGED
The second thing I noticed was that IT WORKED HA HA. In threewave q3w5 under the flag room on the left and right side there is a body on the wall that is breathing. I loaded up OSP right after. In Osp the water on ctf2 gurgles. and the q3w5 body is not breathing. In CPMA the water is not gurgling and the model is not breathing...
Now I know that you said one thing at a time and I understand that im just letting you know what I see.
