@mitu I have. On the Pi, when I plug into the second HDMI port I don't get any display at all. And I've tried all three HDMI ports on the back of the TV as well.
ok, it's got to be the Pi. I just found a backup from 3 years ago. Did the same thing. Audio played fine for the first few clicks, then went out. I'm going to contact them to see if they concur, but since everything software-wise seems correct, that's got to be it.
