I have had this issue since Day 1 as well. Makes the game almost unplayable could really use a fix. Thought Beta would do it but nope. All drivers up to date, have uninstalled and reinstalled several times to no avail, deleted save files and preferences. Please help...

AMD FX-6300, ASUS M5A97 R2.0, SAPPHIRE 7870 XT

Edit: I was able to fix the issue by jumping through a lot of hoops. But the issue is with my USB wireless headset. Doesn't make sense that it would transmit every sound but my personal gunfire but I am now using the headset jack from my monitors speakers.
