TX-578 HDMI video with optical audio

Hi

I want to use HDMI video while using optical audio.
I assigned opt1 for audio and HDMI1 for video to BD/DVD.
When I now switch to BD/DVD I have video but no audio. Once I unplug the HDMI cable, I have audio but obviously no video.
How can i tell my reciever to use the optical audio input while using HDMI Video?

thanks

Hi stevie_8,

Since this model is from our European market you will need to contact them for any hookup advice as we in the USA do not have the manuals available to assist you.
