Just recently hooked up my Onkyo HT-7200 surround sound system to my Oppo BR and Xbox 360, all HDMI in to the Onkyo receiver with one HDMI out from receiver to tv. Cable is hooked to tv via standard audio/video cables. Everything worked fine until I switched all HDMI into receiver. When watching regular cable, there isn't any popping sounds. Now, whenever tv and receiver/components are on, there is an occasional popping sound coming from the tv. I unplug the main tv power cable and plug it back in the popping stops. Can anyone tell me the cause of the popping and suggestions for making it stop?
