Welcome to the forum! What different sources do you want to play through the TV to the soundbar? For example, is it just the Mini, or do you also have cable, blu-ray player, and so forth?
Many soundbars have multiple audio inputs, including analog and digital inputs. My guess is that you'll be fine if you select the proper soundbar. What types of audio outputs does your TV have? If you aren't sure, just let us know the model number, and we should be able to look it up.
