I have a new Sony KDL32EX503 TV. I have connected my old Humax PVR so that I can record programs. This is connected to the TV by a scart lead. I also have a Spider 9000DH receiver connected to the TV by a HDMI lead.

When I wish to watch a recorded program, I select the Humax from the Sony inouts but find that whilst the picture is there, the sound is absent. I've got the sound back by going back to the TV and then back to the Humax. This is very irritating. Is there a error in the way I've connected or may there be a fault in the TV?

Thanks
