My big mistake never researched enough that roku devices do not use Dolby vision. Now trying to see if I can use the avrkey between the lg arc imput and soundbar arc output and using the HDMI audio out from avrkey to HDMI 1 on sb. Tried once yesterday but so far no go need to use the audio from tv for atmos. Any suggestions or am I just out of luck. Only other alternative might be Apple TV 4K just trying not to output any more $$$$ . Thanks. The lg is supposed to pass atmos on dd+ over arc the Samsung is not capable or receiving or decoding it. Any help appreciated. Sorry for the rambling post
Hi, i'm not sure i got this right (the part in bold)
Can you try to detail more what you are trying to do, my guess is that you are trying to feed ROKU > TV directly and then use TV ARC to feed your soundbar, directly or via AVRkey, is that correct ?
The problem here is that AVRkey doesn't have CEC/ARC control, CEC/ARC is not a SOURCE.
AVRKey need to be feed with a valid signal (Video signal and audio signal from any HDMI/HDCP2.x or 1.x source), CEC/ARC is not a valid source signal, it serves a whole different purpose.
This a very informative thread, bottom line, for DD+(atmos) over ARC, you need compatible TV and compatible AVR.
I'm sorry you are having this issue and discover that the industry is marketing feature on one side, while they never mention the other part of the equation must also be brand new matching it in order to work.
Unfortunately AVRkey is not yet ARCkey. We cannot fix all the industry issues and lies at once
For DV playback, you need AT LEAST the following:
DV source, DV content, DV TV.
Now if you have that and have older AVR and need full sound to it, then you put AVRkey between DV source and DV TV and run HDMI cable from audio out to your AVR.
The only setting you have to make sure it's correctly set for DV playback is VIDEO slide switch, it must be set to SINK (middle position).
Here is first feedback we received for AVRkey on our support server.
Got mine today! Works perfectly! Many thanks, I have been waiting for a product like this to solve my issues for along time! avr-key is working perfectly first time. Well done and thank you!
