I had to send my Pioneer in for repairs, so for the time being any audio must come directly from the TV speakers. The problem is that I cannot get any audio signal from the TV. I've made sure that the TV Speakers are set to ON in the Advanced audio menu, mute is off, volume is up high enough that it would be audible. I am using HDMI sources only, so the inputs are set to Digital sound. I've run out of ideas. Does anyone have a solution?
