Ok so idk what i did, but something happened and now the audio on my computer is totally screwed up. I can still listen to stuff (thank god!) but everytime i go to record, it records a loud, fuzzy sound instead. What's going on and how do i fix it? can someone help please??

- also, i suspect that the problem started when i tried to record with headphones in. Has anyone ever had this happen to them? and how do i fix it?? it really sucks...
