Check your weapons sound alias, like fireSound\\ and fireSoundPlayer\\, see if those exist in your sound csv.

Yeah they do. Non of them are canceled out too. All codes match up. Still doesn't work.
I actually decided to remove all waw guns and replace them with BO guns. So that fixed my sound issue with non upgraded weapons BUT what about the upgraded ones? It doesn't seem to work. They are silent.

sound,weapon,,all_sp

Sounds like your not including the weapons.csv file in your mod for the world at war weapons sounds, which is where the upgraded sounds are located and would explain why they aren't playing. Remember to include a line such as:

sound,weapon,,all_sp

Within your mod.csv (or any csv being loaded into your map. The other option would be to add the upgraded fire sound aliases to your sound alias for your ported weapons.

Thanks, My PAP gun has the sound but it's super low. I guess it's better then nothing.

Have you tried increasing the volume on it?

How do you do that for the guns?

In the sound alias, the first 2 numbers after the file directory are the minimum volume, and maximum volume

It didn't work. It's alright, this maps pretty much done unless YAW decides it needs work.
