microsoft kb3000850 and sound quality!

Hey all Microsoft just released a KB update kb3000850. this update completely annihilates all the sound quality i once had with my Soundblaster RX. heres the kicker. this update used to be optional. but since quite recently it has beccome reccomended/mandatory. ive been putting off installing it because it just makes my music sound like white disorganized noise... NO lows and very crappy highs. I dont know if i dont install it will i still get access to things like security or framework updates down the line?



Thanks
