This just started happening: I have a Yamaha RX-A1020 AVR, Yamaha BD-S477 blu-ray, and Sony Bravia 50" LCD TV. all use HDMI. When I leave a dvd in the player and power on the system with my Logitech Harmony 650 remote, the speakers will pop, the AVR display panel will flip-flop between 'decoder off' and 'Dolby Digital' and video is okay. Only the audio is affected. When I power up without anything in the player, no problems!
