Is there a way to add a custom fire sound to a weapon that is already there, such as the walther p39?  I wanted to know because I have a sound file I got for TESV: Skyrim and I thought it would be cool to use it for the walther, but when I change the sounds to the sound I want, there is simply no sound at all when firing.  Any ideas?

Did you change the sound in the Sound aliases too?

Well, I tried to, like I changed one thing but I wasn't sure how to actually edit or make a new soundalias file because of all the codes like this where I changed only the 2 sound names, but I get no results.

And then there is like another 10 - 20 different lines in total.  Just for fire sounds from what I can see.

Well if you did build sounds right and edit soundaliases it should work.Try to rename the new sound to the old one and just replace it
