Some TVs may an optional audio selection directly on the remote control. It allows to select what audio feature you want and of course, select it. It may have what you want but the required sound bar and/or connections need to be correct too. Thus, it can be selected properly but "NO" audio is outputted which may infer either no true ability or no path for that selection. Understand, all these feature become a PITA and having the correct config setup is just as important besides the h/w based features needed. In other words *ALL* has to be right and with all these setting, things can go awry. Just my 2-cents -----Willy
I purchased a Yamaha sound bar recently for my bedroom and it's connected to my Toshiba TV via an optical cable. While the sound is good it isn't true Dolby Digital surround sound , it's most likely only 2 channel stereo . To achieve the Dolby Digital I would have to individually connect both my blue-ray player and my Direct TV receiver audio outs to my optical in sound bar. The problem is the only out ports on both my Blu-ray player and the DirecTV receiver are digital outs, not optical outs. What I would like to know is if it would really make that much of a difference in sound quality in a sound bar to purchase digital/optical splitters to connect it those Dolby Digital surround sources? I would have to get two of them ( I cannot find any splitters with two digital ins and two optical out ports in one unit). and each splitter would need a plug in for their individual power sources. Once again, would this make that much a difference in audio quality for a sound bar?
