Windows 8 Laptop speakers are inconsistent?

Recently I noticed that my laptop speakers aren't working consistently at all. Sometimes I watch youtube, listen to pandora, and everything will work fine. Other times it won't work at all. I've been getting by like this for a week, but now it seems like now the only audio my speakers will play is a notification sound. I still have the computer under warranty, and I can take it into the store and get the speakers fixed. However, I was wondering if there was a way I could skip all the trouble/paperwork of taking it back in? maybe I just clicked something I shouldn't have?
Any tips are hugely appreciated!
