So I recently got a new computer, the asus g771jm and it worked like a dream until I started to notice a weird cutting in and out with the volume of the background sounds. If that makes any sense. This is especially noticeable on the opening screen of left for dead 2 where there's things sort of buzzing that increases and decreases in volume then cut's randomly. I thought this might be due to the actual music track but on my desktop it doesn't make any noise like that which I can discern. I have tried outputting the audio to two televisions and using headphones and the same thing happens so It's probably not the laptop speakers. I've tried everything I can think of to fix it like drivers for everything and whatever I could find online through changing settings and whatnot but to no avail. This is my last ditch resort before taking it back to the store and seeing if they can fix it or get a new one to see if it retains the problem. Thanks for any input, I look forward to hearing from you guys.
