I have trouble with TV sound, at times it is dead the picture on the TV is fine, when sound returns the picture is a little pixel'd done the sound and picture is returned fine. This is with DirecTV H10-250 receiver the H10-250 is optical output to the AVR, also HDMI output to the TV. So I tried this HDMI input to TV optical output from TV to AVR, works ok but if the channel is DD then I get nothing, if the sound is normal it's fine? Can the TV do DD output or is it the HDMI cable? I'm using the same cables for all my checking inputs.
