From the review I saw on CNet it said that many HDTV's downmix audio to stereo when you use the optical connection.
Any help would be appreciated. Thx.
I use a Sony HT-CT150 sound bar with HDMI switching so I can't directly answer your question.
That makes two of us. I have an Xbox 360 which excepts HDMI. How do I get 5.1 with the HDMI into the TV and the Optical from TV to receiver..
BTW... LOVE LOVE LOVE this TV!
optical outputs (from most all TV's) will only output PCM stereo from externally connected devices. Only the internal TV tuner will output a Dolby Digital signal.
If using a soundbar, I wouldn't sweat whether it's Dolby Digital or not. Just set the soundbar for Dolby Pro-Logic. It will sound better than TV speakers.
Only FIRST goto Input Select and select TV that will add to the menu pulldowns for Digital Setup - you will have an audio selection - otherwise
When you go to digital setup on the top menu all you have is software update. You do not have the Audio setup selection
The Audio selection is PCM or Dolby Digital - just like the manual states at that point
My old Integra 6.4 has a display button that reveals what the input signal is. When I flipped the PCM output from the Sharp the PCM display appropriately disappeared. All my issues haven't disappeared as hoped using the single optical out from the TV.
I have some more investigating to do. But at least whatever Sharp does is now available to investigate.
I have just received a similar Sharp TV (LC-70LE550U) and my sound bar is a Yamaha (YSP-2200) with 3 HDMI in and one out. I have a PS4, a cable box and a computer all with HDMI out. With the TV I had before, I would connect my 3 HDMI components to the TV and the digital audio out from the TV to the sound bar and that worked fine. Now it does not work. :(
Since I have so many inputs on the sound bar my next attempt should be to get my 3 HDMI components into the sound bar inputs and connect the sound bar HDMI output to the TV (and do away with the digital audio cable all together) right?
I'm missing one HDMI cable so that is why I'd rather ask before heading out to buy more cables.
