Does the audio return channel support sending Dolby 5.1 from sources such as an Apple TV or cable box?

Sort of, but on my Yamaha system with a FIOS DVR cable box (never a problem), the Samsung TV 60" 3D ARC.... it is difficult to get the Yamaha to be in charge of the sound. I find that I can start the Cable box, then the TV which in turn turns on the Yamaha, so far so good. Often the Yamaha comes up on HDMI 1, where it's plugged and with 5.1 channels enhanced, but then the TV messes with it and looses the sound so it reverts to the native sound in the TV, argh. I use my Yamaha controller to reselect the HDMI 1 input and more often than not it allows the Yamaha to takes over the sound. Not very smooth and a bit complicated for my non teen kids.

I have mine hooked to a surround sound system through both a cable box & my receiver. It's fine.

I added an optical audio return, which allows all digital sound transmission without distortion. My receiver does not have HDMI RAC capability. The only complication is that you need to turn the tv sound totally off, to avoid an echo effect. It may be possible to sync the two sound sources (home theater and tv speakers) but I have not tried, since the tv speakers are crap compared to my system.

I assume you are looking to run the audio out from TV to an audio receiver or similar. The Audio Return Channel (ARC) running through the HDMI connector labeled for ARC appears to only support stereo (2 channel) audio. The original source should be irrelevant. I have a Sony 7.1 channel audio receiver hooked up and attempted to run all my sources (Verizon FIOS box, PS3, etc) directly into the TV and then have it forward the audio to the receiver via ARC in order to avoid having to use the HDMI video switching in the receiver. However I found that it took my 7.1 sources and only passed through 2 channels (L/R)!!! It's not clear whether the TV internals or the connection is limiting this, but if you dig into specs you'll see that the quality of audio that you'll get via ARC is dependent on what the device is built to send through and TVs often only support 2ch as their own built-in speakers are limited to this. With this TV however, you do have the option of using the optical audio out connector from the TV to receiver which does support 5.1. It does NOT support 7.1. Since I refuse to have two useless speakers I had to wire all sources back through the A/V receiver first and then a single HDMI out to the TV so the TV is not in the audio path at all. The drawback is less clean input source changing but I can live with that. The only exception is when the TV itself is the audio source for example when using the Apps like Skype, Amazon VoD, HBO Go, etc. For those I used the optical audio out from TV mentioned above which results in a good 5.1 to my audio system (I doubt the apps or their content really support 7.1 anyway). Sorry for the lengthy explanation, but as I learned there are a lot of details to this. If you only care about 5.1 and not 7.1, then I suggest you use the optical audio instead of ARC and then it should work fine at the very least for any HDMI input to the TV (I haven't tried any others).

This unit as far as I have read has a conventional RCA Plug style red and white stereo input that would work with an original Xbox flawlessly if you use the supplied Composite A/V cable for the xbox. As far as getting 5.1 surround sound from that connection I am unsure. I am sure that there is an adapter somewhere that plugs into the xbox and outputs a digital sound signal of either optical or coaxial types.

The problem is 5.1 vs 2.1. Anything in dolby 5.1 needs a center channel speaker to hear the voice track clearly. Change the channel to 2.1 and you will hear the voices. Netflix is one service that offers this easily and hopefully others will get onboard.

Turning surround 5.1 to stereo work great. I run my TV audio to my stereo receiver as an option for movies or sports anyway so I didn't notice any difference

I tried a separate cable from the Comcast set top box audio to the 5.1 system (coax then optical then RCA).All were out of synch with the internal speakers.

All of the input/output connections on the back panel EXCEPT for the digital output use the common 1/8" DIN, male stereo cable. Note that if you want to produce Dolby 5.1 or 7.1 Surround Sound, each output needs a cable.

Without knowing more about you setup (type of TV, etc.) I cannot answer with certainty. If you have the receiver and the TV connection via HDMI from the receivers HDMI out you might be able to use TV audio return channel. Otherwise connecting the optical cable should work, just make sure you have the correct mode selected on the receiver. I believe it is TV but it could be different. Check the manual.

For what it's worth -- if you are watching broadcast television via antenna the LG60PN6500 TV has a Toslink (Digital Optical Audio) OUT connector that you can output the audio signal to a receiver/amp with. If it's broadcast in 5.1 You'll get the signal that way.

if you connect your TV(the optical Output) to "Digital to Analog Audio Decoder"in the optical input and then connect your speakers to "Digital to Analog Audio Decoder" to the analog outputs work in 5.1,if you want to connect the TV directly to the speakers, your speakers should have optical input and yes works in 5.1

From the user manual: "1.1 Features 1. Convert DTS/AC3 source digital audio to analog 2.0 ch stereo audio output" -- The device does this quite well, although I did have to trim back the sampling rate of the optical output on my computer a bit to avoid some distortion. However it sounds like this is not what you are looking for. What you want would be probably be a true decoder, which means plenty of $$$$

Yes! 5.1 still works fine, I haven't tested 7.1 but I expect the original audio stream is passed straight through so anything that works over HDMI should work through the box.

5.1 Surround Sound is a product of the A/V signal itself. You can get a AV Receiver and hook the signal to it and then come out of the audio system (AVR) HDMI to your TV, and since the signals are all digital, there will be no degradation of the quality. My girlfriend has an older 5.1 system that gets its audio information encoded from the video signal, and uses an older Composite (yellow) video signal to decode the audio information. You can even get the audio from an HDMI on some systems. Check with the system you are interested in...and then shop around for others. On the back there is one stereo headphone jack that you can use as a stereo analog signal to hook up to a regular stereo system/amp/etc. Here is what LG has to say about that TV: Daniel: Hello Joe Smith. Welcome to LG Electronics U.S.A. Support only. How may I provide you with excellent service today? Joe Smith: Hello - Joe Smith: Concerning the 47LA6200, does it support Surround Sound and if so, what port do you hook up a system to? Daniel: I would be happy to help you with that. Daniel: I would like to please place you on a brief hold while I research that for you, will that be alright? Joe Smith: YEs, thank you! Daniel: You are welcome. Daniel: Thank you for your patience while I researched that for you. Daniel: You can hook up a sound system on the optical port. Joe Smith: Does it support 5.1 Surround or just stereo? Daniel: It will support both. Joe Smith: Thanks...have a great day! Daniel: You are welcome! is there anything else I can assist you with today? Joe Smith: Nope, that's it. Love my LG TV! :-)

The unit has one fiber optic line that carries the digital signal to a power converter separator to an audio signal to be read by an amplifier. Thus the signal is then converted to Dolby stereo sound by the way of the amp. I would say that it would not convert to Dolby or com. I hope this helps. Mike

Set the audio output mode for the Apple TV:With your Apple Remote, select Settings > Audio & Video.Change the Audio Output setting from Auto to 16 bit.Turn off the Dolby Digital Out setting (your TV or receiver may not be properly detecting a Dolby Digital signal): With your Apple Remote, select Settings > Audio & Video.Change the Dolby Digital Out setting from On to Off.

It decodes dolby 5.1 to stereo. It's not the highest quality product, so I don't recommend buying it.

Here's a possibility: USB Multi-Channel Sound Converter With 5.1 7.1 Surround I haven't tried it yet but there are many positive comments

It will decode Dolby Digital 5.1 and down-mix it to 2.1. It will not decode DTS.
