Let me start by saying I am not very good with electronics. I have a Pioneer sc122 receiver and am setting up a zone 2 in another room of my house. Upon connecting my pioneer to a sony receiver in another room I have lost audio in the main zone for the PC I have connected to the pioneer via rca cables. I also have a PS3 connected via HDMI and no longer get a signal at all. I sometimes connect a laptop via HDMI and only receive audio in the main zone. My question is what is the best way to connect everything, it would be fine if both zones play the same audio source at the same time. Also if anyone knows what would be causing these issues.
