I recently purchased a TaoTronics soundbar. The problem I'm having is the sound only comes out of the left channel. I know it's the soundbar that is broken because I've connected it to several devices (computer, phone, tv) and I've connected it by cable and bluetooth but I'm still having the problem. Does anybody know how I can fix this soundbar? Are there replacement parts I can buy or should I just use it as a mono speaker? Thanks
