It only sends Dolby 5.1 when you are watching OTA content.
Even though arc is great for ease of use. That is it's major downfall. The tech supports it, but I believe it is a licensing issue.
The NX810 does pass 5.1 through its digital output, the limitation would be at the sound bar or reciever end.
A given sound bar would have to handle Dolby True HD or Master DTS as an example. Also what settings it has would have to be set correctly.
Although I could not find anything specific on this in the imanual or Sony Website a chat session with Sony confrimed it. See the following;"You are chatting with Owen - (C3L6).Sony Electronics9:44 AM Connecting...9:44 AM Connected. A support representative will be with you shortly.9:44 AM Support session established with Owen - (C3L6).9:44 AM Owen - (C3L6):Hi. Welcome to Sony Online Support. I’m Owen.9:44 AM Owen - (C3L6):Please allow me a moment to review your concern.9:44 AM Customer:hi owen9:46 AM Owen - (C3L6):Thank you for waiting. I'll be glad to assist you in providing the information about the Optical OUT port on the TV.9:46 AM Customer:thanks9:47 AM Owen - (C3L6):Yes, the Optical OUT port on the TV provides 5.1 channels surround sound. It depends upon the Receiver/Amplifier/Home Theater to output the sound in 5.1 or 2.1.9:48 AM Customer:what does that mean..the TV pass's 5.1, it depends on if the reciever or sound bar reproduces 5.1?9:49 AM Owen - (C3L6):The TV will always pass 5.1 channel digital sound to the connected Audio System. You can change the settings in the Audio System to 2.1 or 5.1 according to your requirement by changing the sound fields.9:50 AM Customer:ok, that pretty much answers my question, thanks9:50 AM Owen - (C3L6):You're Welcome.9:51 AM Owen - (C3L6):Based on our conversation, this is the help you were looking for. If you need any additional information feel free to stop by our chat room again using the same email address.9:51 AM Owen - (C3L6):Have a great day ahead."
With my system I am using a Yamaha RX-V667, I have all components going into the reciever via HDMI and ONE HDMI cable going out from the reciever to the Sony NX810 via HDMI/ARC 1. Using HDMI control, every thing turns on together and the internal speakers are set to external audio system, all audio goes through my reciever. There is no guess work with my reciever as its on screen menu tells you exactly what the incoming signal is down to its bit rate and encoding type.
Back in the day (a year ago) i had an older Westinghouse 1st gen 1080p HDTV and even its audio out supplied 5.1 if the source was 5.1.
I would suggest you look at the settings and or specifications of your system and or consider upgrading it.
For future reference going to the Sony NX support site you can enter support chat or on your TV's remote press Menu/Settings/Product Support/Contact SonyGood Luck
