I have a Sony digital audio/video control center (STR-K900) and just got a bell pvr receiver. I connected a HDMI cord from my pvr receiver, to the HDMI video 2 IN on my sound system, and a second HDMI cable from the HDMI monitor out on my sound system, to the HDMI connection on my TV but my speakers are not working. It seems so basic but can not understand what I'm missing. Before I had a 6141 HD bell receiver and it worked then
