Roku Ultra causes HDMI-CEC issue
Setup: Roku Ultra is connected via HDMI to Sony Bravia XR85, which is then connected to Sony's eARC via HDMI to Arcam AVR 20 Sound System. (Also, have DirecTV Stream and Apple connected to Sony, but disconnecting them doesn't fix the problem, i.e., the issue is w/ Ultra, not other devices.) All HDMI is very High Quality.
The problem: when Roku is connected to the TV, it switches the setting "Bravia Sync Control" to go from greyed out to not greyed out. This causes the Sony Remote to no longer control the Arcam Sound System. I.e., when Ultra connected the Sony/Settings/Channels & Inputs/External Inputs/Bravia Sync Settings/Bravia Sync Control, which must be greyed out and in the "On" position for the remote to control the Arcam Sound System, goes from greyed out to NOT greyed out and the Sony Remote stops controlling Arcam.
3) Questions: 1) Does anyone have a solution for this? 2) Does Roku have a fix for this? Perhaps a firmware update? 3) Does Roku have a better device that doesn't cause the problem?
HDMI-CEC is tricky, but other devices, like Apple and DirecTV Stream, don't cause problems.
For others researching how to get the highest possible video and audio: if you have a high-end Smart TV with a good processor, then simply use the Apps on the Smart TV to get the highest possible streaming bitrate for video but also for audio. This minimizes connections--pass thoughts or otherwise--other processors, any device inadvertently downgrading the quality, etc. You have to make sure your TV's processor isn't downgrading the stream because it can't handle it. Get sound to the AVR through the TV's eARC return, and you will still have an audio stream that your AVR can manipulate and then send to your speakers. Use CEC to control the volume for the AVR, power, etc. with your TV's remote.
Unfortunately, this makes Streaming Devices like Roku, AppleTV, etc. mostly obsolete. Roku is still valuable if you want Streaming services for which your TV doesn't have Apps. Also, if you prefer a particular remote, you will lose that as SmartTV Apps work with your TV's remote. (And be aware that the TV remote controlling Smart TV Apps is typically less than ideal.)
Also, connecting everything through the TV and using that instead of Streaming Devices will minimize the problems that can come from HDMI switching.
And lastly, while the old way was to send everything to an AVR and then out to the TV and speakers, in today's world of: ever higher bitrates; ever higher-end processors in TVs; the possibility of connections and pass-throughs inadvertently degrading the stream; the problem of running an AVR that sits behind a wall; the incredibly complex remotes of AVR's; and more; the best thing to do is run everything into a high-end TV and then using the AVR only for sending sound to your speakers in whatever you way you want. Soon, we will see very high-end devices replacing AVRs as all they have to do is take one eARC HDMI from the TV, no matter what device is being used to get the image on the TV screen, and then send whatever type of sound you want to your speakers.
I wish someone had told me this when I was setting up my system; it would have saved me enormous amounts of time and headaches. Hopefully, this will help you.
Love the wife comment. As the saying goes I resemble that 😂
For those who are following this thread to try and figure out the best possible way to wire their system for the highest possible video, audio, reliability, and ease of use, you now have everything you need to make a decision about wiring through the AVR, as suggested by atc, or through the TV. The key being that for many years AVR has been the only way to do this, but that it can now be done for some just as well through the TV. And for several reasons outlined in the thread, It is better for me to go through the TV.
Happy streaming.
