edit: read past this first part, this was my previous error and now i'm realizing it's something a little weirder.using chrome, trying to view youtube videos, and everything i look at is played 2x faster than usual and the audio is horribly deformed, scratchy, distorted; so it basically sounds like my computer is possessed.
google results suggest that i have a bad plugin for flash, but i only have two and neither of them are fixing the problem when i enable one by itself and try loading a video.

edit:
alright so i've made multiple audio tests but nothing is working, it's always scratchy and weird and the videos off youtube still play really quickly
but then i got a windows error and noticed that the error sound also played very quickly and strangly
so i've started up some different steam games and even a music making program off to the side and all of it goes twice as fast and its audio is always played scratchy and strangly. it's something wrong with either my headset or my computer, maybe a virus. i doubt it's my headset causing my computer to run twice as fast, though.
