Onkyo TX-SR578 setup


Standard Member
Hi, this is my first post and I'm looking for some help with my home entertainment setup.

I have a Sony KDL-40EX703U TV with an Onkyo TX-SR578 home cinema amp. Currently, I only have composite inputs from Sky+, a DVD player and a Wii going into the amp (I will be upgrading to HD input devices, but not yet). And then I have HDMI out from the amp to the TV. I was led to believe that with the digital upscaling functionality of the Onkyo 578 amp I would be able to achieve composite in, HDMI out.

The issue I have is that I can get the video to pass through to the TV via the HDMI lead, but I don’t get any audio through the TV using the composite inputs as the source.

Could someone please give me some help as to what I’m missing in the setup?

Thank you.
