Not sure how quiet is very low volume you speak of but the speakers on laptops are pretty weak so with one I had and, the one of my dad's i used to use, if i was in a car, plane or it was a quiet part of film i could barely hear it. Try some headphones or speakers when you've got it on a desk and if its still quiet then you know its a settings problems. i know it doesn't fix it but it is the only way i could hear my laptop most of the time if there was more a little background noise.
