I always get made fun of when I use punctuation in the game. People ask me, "Why are you using periods and commas?" I always reply, "Because that is how English is spoken."
I'm usually always content with around 5-6. 8 or more hours and I feel like I've just wasted that much more of my day. Much more than 8 is generall bad for you anyways :P i once stayed up from 9:00 pm to 5:am the next day playing LoZ: windwaker. You got me before I changed it :P That's an isolated incident though, if you do it nightly the effects become apparent only did it once, school started after that and then it was early sleeping. But i did stay up untill 12-1 sometimes, now i stay up untill 11pm for RS. I normallu go to bed around 3 am and get up at 5:30 am for school on weekdays, but on weekends i sleep 14-20 hours a day. During the summer i tend to stay up for 3 days and sleep for a day.
Or, your speakers could be malfunctioning. Borrow some heaphones or speakers from a friend or use some different ones at your house and see if you still hear the noise.
