I dont know if any one is having this problem and i have checked the forums yet. I was wondering if anyone is getting this problem with the minigun. Every time i shoot the minigun and stop the sound of the gun being fired continues even when im not shooting, and its also in like a sequence every three seconds i think. When i unequip the minigun the sound stop. I tried reinstalling my game from the hard drive, re updating and redownloading my content as well and it still does.
I hope the info that i provided will help and be in the next update. It makes my new vegas adventure not fun with out a sixy minigun.

It's an issue that was apparently never fixed from Fallout 3, I, a PS3 user, also experience this annoying issue. Hence I mainly keep a Minigun as a decor for my home.

Also, a quick tip, you don't need to uninstall it. Just leave your current game, go to the main menu, reload the save, and problem solved.

I get sound issues when using the Unique minigun but not the regular. I have to mute the sounds whenever I play, which is lame.

theres 2 ways...
1 way is to save and reload.
the other way is move a distance away from the sound's orgin and the gam will fix itself eventually... but DO NOT USE the MINI GUN anymore...until whenever the next patch comes...

You figure that with such a cool weapon that Bethesda would actually take the time to fix such a small bug. Its one of the most badass weapons in the entire game and i hate using it because the damn sound irritates the [censored] hell outta me, I like the Light Machine Gun but nothing quite compares to the use of the Minigun to mow down ones' opponents in such a supremely cool manner. Ive found that the Avenger does not make have the same sound issues, if you use the Avenger in VATs it does not make the sound on an infinite loop like it or the regular minigun would outside of it.

I never had problems with the minigun on fallout 3, but I do on new vegas which is really frustrating since I love the weapon. I have yet to try the unique minigun, so maybe I will give this a go. I figure if they have not fixed it in the latest patch then they simply are unable to.
