From what I'm reading, BigBubba is right. You should be able to play music through the soundbar just fine. If there's a store nearby that has one on display, see if you can get it to pair with that one. Then you will see if it's the soundbar that is the problem or not.
I'm going back to school to major in Vetrinary Science and Taxidermy. So, either way you'll be getting your dog back!
