When I run the PC power to another room and keep the hdmi plugged into avr the noise diminishes significantly, but does not go away.
I have finished running the wires and connecting everything with all HT components on same plug (including the PC which is plugged into an isolation transformer) and the result is very similar to what I had when running the PC on extension to another room.
There is still some noise but I think I can (will have to) live with it.
I greatly appreciate all the help, thank you
