eARC when using Roku

All you can do is try it.

In my experience I'd never seen a TV pass surround channels.

Not an issue for Roku. 

Well, I'm pretty sure you would be able to tell pretty quickly if the video suffered.

Personally, I would run everything through your Lyngdorf and keep it simple. I've also never seen an Audio Return Channel that was all that reliable.

FWIW, I found switching back and forth between streaming Roku and broadcast over the air TV much easier with the Roku directly into the TV then to my Oppo 205, than when the Roku went directly through my Oppo 205 then to the TV.

Ok so you are running video/audio from Roku to the TV then running the audio back from the tv to the opposite 205, is that a processor/receiver?  If that rout is correct are you using eARC and if so do notice any advantage on two channel, Tidal etc, playback?  What I am trying to determine is the advantage to EARC other than its bidirectional ability.  I am trying to maximize two channel playback of uncompressed audio files,PCM, using streaming sites such as Tidal and Amazon..  As far as video the processor that I have the Lyngdorf 60 2.1 does not process video it just allows it to pass through without diminishing the signal.

Thanks.

The Oppo 205 is a multifunction player, digital line stage and DAC. It too allows for pass through. Though the internal video processing is probably better than most. Though capable of multichannel, I only use it’s dedicated 2 channel output currently to my audio only line stage, as I still have analog source as well. The Roku goes directly into the TV, the audio then goes through the TV’s ARC HDMI (optical is another option) output into one of the Oppo 205’s preferred HDMI inputs (optical is another option, but that input is being used for a D-VHS player's digital audio output). I’m not yet using a dedicated audio streamer. When I do, it will go to the Oppo 205 through a different input.

Ok I understand your set up. Do you notice an improvement in audio using the audio return channel back to the Oppo vs direct connect Roku via HDMI to the Oppo?  Is that Enhanced Audio Return or ARC. Do you set the digital output on the Roku for two channel uncompressed files?  In your opinion would I have anything to gain in two channel playback If I direct connect the Roku to the TV and use the eARC to push the audio signal to the Lyngdorf.  The only reason I ask is because all the cash I put out for this system which functions as stereo and home theater function. 

Thank you

I originally had the Roku going into the Oppo 205 then into the TV, I then changed as outlined previously.  I really didn't notice a change in sound quality. I think this has more to do with the audio signal sent through the Roku. Most of the audio seems to be almost mono. I think they want to keep the attention on the screen. Concert casts can offer some more soundstage, but is not comparable to say a CD. Again, I suspect this isn't due the technical capabilities, but rather to what signal is being delivered. I currently use ARC. Yes, I do set the Roku for two channel uncompressed files. By directly connecting the Roku to the TV you might get a purer more direct with less chance of other electronic noise video signal. Putting the Roku directly into the TV has reduced the number audio dropouts that occur. Though this happened so rarely that it's hardly worth mentioning. For me(!) putting the Roku directly into the TV has had one distinct advantage.  Sometimes, on Sunday mornings I'll watch broadcasts of soccer games that have foreign to me language commentary. With the Roku directly into the TV I can mute the TV audio, and simultaneously listen to music of my choice through the Oppo 205. The Lyngdorf offers so many other features that I don't think I would feel short changed.

Ok thanks for your input. Its seems like there is much guess work when it comes to optimizing the audio.  Much  money is spent for items downstream from the signal ie. ac cords, speaker and interconnects and the issues may be the signal path that is  chosen.   I think I will keep the connection of the Roku to the processor for now based on your experiences.  Do you have any thoughts on the higher end ethernet and HDMI wires?  Thanks for your time.

We're using different devices in different locations. What works best for me, might be different than what works best for you. Your Lyngdorf seems to work as advertised. The only advantage to my set up is independent Roku video and independent audio output. I don't have any thoughts on higher end ethernet wires, and though I don't use them, respected videophiles seem to regularly recommend Wireworld's HDMI cables. 

Ok Thank you for the input.

I've personally found things better running in through the TV and then out via ARC.  But not always.  Your SSP is pretty top level, so I can't imagine their video switching/passthrough isn't done right.  With some setups, I would get more judder running everything through the SSP.  So like the user above said, it should be obvious if you see anything wrong with your current arrangement.  Roku is all loss-less audio anyway, so you have nothing to lose by trying the HDMI directly into the TV.

Ok thanks. The video pass through the Lyngdorf seems to be good with the exception of running the game PC video through the Lyngdorf.  I think that the Nvidia variable refresh rate software of the GPU causes issues with the video pass through of the Lyngdorf.  Otherwise pretty happy with the Lyngdorfs audio is superior to the Mcintosh MX 122 it replaced. I read what Unsound wrote regarding wire world HDMI and just ordered the fiber optic 2.1.  See what happens

@guyt I also run fiber optic HDMI cables for every gaming system I own (Switch, Xbox Series X and PS5).  Still using copper for my video streamers though.  I already own AQ Carbon and Vodka 48, so may as well keep using them.  But no issues with the fiber optic cables.  And I mean that the Roku is all lossy audio, not loss-less.  Sorry about the typo.

Ok I bought the fiber 2.1 optic HDMI cable from wire world pretty pricey.  The cables I have now, 2.1 Austere, work but the run from the PC GPU to the TV at 4k 120 hrz creates some image flutter, small isolated vibrating lines during game play.    So if the Wireworld HDMI cleans the image problem up I will think about buying more.   As far as Roku/Tidal I am surprised how well it sounds in two channel playback.  This is the first time I used Roku and Tidal after switching amps and processor and the sound quality is superior compared to my old system. The audio improvement may also by attributed to playing uncompressed files.  Anybody have an opinion on ethernet cables?

Thanks
