I have fully working ported guns with pap camo working fine, however the pap firing sound isn't working.
I have a .wav of the sound I want to use in the same file as the other ported weapon sounds, I am using the UGX Weapon Editor to set the pap sounds, all other sounds work fine, but not firing sound.  The .wav file is being built into the mod alongside the weapon file that is set up using UGX Weapon editor.

My regular MP5 firing sound in the editor looks like this:

fireSound         wpn_mp5_fire_npc
fireSoundPlayer         wpn_mp5_fire_plr


and my Upgraded MP5 file looks like this in the editor:

fireSound                 wpn_mp5_fire_upgraded_npc
fireSoundPlayer           wpn_mp5_fire_upgraded_plr

the regular working sound is called mp5_fire
and my custom one is mp5_fire_upgraded in my mods folder. both .wav
in game the sound doesn't work right and is a distorted, really quiet sound.

can anyone identify what is wrong or how to sort it?

In your soundaliases, have you made a fire_upgraded sound path like you did with the fire sound? If not, then it wont work

Worked perfectly! Thanks a lot. I didn't have the correct soundalias set up, all I did was copy the non paped one and add _upgraded to it all       worked fine Although a slight problem, my pap fire sounds are quieter than normal guns or pap sounds, and if I use audacity to raise their db and turn them up too much they become distorted...

You can change it in the soundaliases by changing the numbers after the path. For instance in this,
it shows 0.8,0.85 the first number is the minium volume a sound will play at, the second number is the maximum a sound will play at. I believe the max is 1.0, so you can change it to how much you want before 1.0.

I believe the max is 1.0
