Woke up this afternoon only to find that something happened to my laptop while my brother was using it. The startup sound plays normally when I turn it on, but other than that no audio will work from what I can tell. Is there any way to fix this? I'm still relatively unfamiliar with all of the specs of my laptop, so I'd need a detailed walkthrough of the fix. I've had this thing for just under a year and this is the first time this has happened, if it helps any.
EDIT: It seems I still get sound when I use headphones, but without them there's still nothing.
