you need the correct buttons file for your version, if not some sound will not work
if you open any prs files you can edit the spl value for higher/lower volumes
if you want only the external to be less loud then you need a wav editor to change the master volume
agree with Vpmedia, if the problem persists then i recommend using sound forge or a free version calle Audacity. very easy to use. Open the file, highlight the sound and increase or decrease the decibels (DB) only by 3 to avoid distorting. Then export as Wav.
You know, after I installed some patches (And I think the latest AAA mod pack) it seemed like some of the guns were using different sounds. When I had first installed the sound mod the .50 cal's were changed from a blender blade "Whiiiirrrr" default to a real gun like sound. Suddenly they sounded like a Cuisinart again...
Thanks tons fellas, but where are these gun prs files in the 1946 folder? I have only found the engine ones...
