Trying to turn off my TV Speakers (TLC TV) but do not have that option available. I go to settings, then to audio then there should be a speakers button with an option to turn the speakers on or off but I do not have that option available?!? Has it been relocated on the menu, I cannot find it anywhere? Is this a software or programing issue with Roku? UGH! So frustrating. Thanks for any advice or insights. T
