no sound through speakers? hdmi from tv to dvd home theatre, and coax from cable box to home dvd home theatre ?? tv has no arce dvd home theater no digital optical ?? and still cant get cable remote to work on all???
So the HDMI connection from the DVD player would be for the DVDs you play on that, do you get image but no sound? Same thing for the cable box, the audio out is going to the Sony home theater and the video out goes to the TV? You may want to take some pictures of all the connections and post them here so we can see what is connected and how.
