Sound isn't working on my Dell Inspiron 1525 after the 13.10 upgrade.

I've been looking around for a fix, but no luck. My sound card seems to be in working order and all the indications in the sound menus seem to be fine, but it's mute all around. If there's something I'm missing please let me know.

Not sure if it matters, but the sound icon on the top menu bar was present, but after the fixes I attempted it disappeared. Any help would be great!
