I have a Samsung LED TV (UN55EH6000F). It is being fed by a Dish receiver, which runs into HDMI 1 of my Yamaha tuner (RX-V373BL). This works well. However, sometimes my wife wants to just turn on the TV and watch using the sound of the TV speakers without messing with the tuner. Unfortunately, there is no sound in this configuration (at least, I’m not getting any). I would appreciate any help you can give me in working through the problem.
