ARC on 2017 LG B7

Question

I have been trying for 2 days to get ARC to send audio to my new Anthem AVR from streaming sources. First off I installed a new Premium certified HDMI cable. I have enabled ARC and the Simplink (CEC) in the LG, digital sound is set it to Auto. I have enabled the same (ARC and CEC in the Anthem AVR. I always get the screen on the Anthem displaying "No Signal"! Is there some other hidden or hard to find setting to get the LG's ARC channel to work properly? Anyone else been through this problem and found a solution?

@radtek2 I seem to rmember on my LG there was a setting for the sound to ensure it is sent out via HDMI, rather than Optical or Internal speakers, did you do that on yours?

@td47  the sound setting on my B7 has a combined setting.  It is Optical/Arc  also if you want ARC you have to enable Simplink which is LG's version of CEC. I have done both but the only audio I get is out of the Optic port not the Audio Return Channel. I am getting a new Premium Certified HDMI cable today and will try that. If that doesn't work I  figured out a work around which will tell me if its the LG or the new Anthem AVR . I have a Oppo 205 BluRay player and it has ARC on its main output and also a dedicated Audio Out  HDMI which I will connect to the Anthem. If i have a functioning ARC channel then I know it is the LG if I don' it is more then likely the Anthem. I say this because the Oppo 205 is one of the most solid players ever I have not heard one squeak about its ARC not working.  I just don't know why this has to be such a struggle. I mean ARC has been around a number of years now it  should have all the bugs taken care of by now.

@radtek2 That does sound rather like a B7 Firmware bug (it should be able to detect which is the "active" one).  Have you by any chance left the Optical/Toslink cable still in place and connected somewhere, as well as the HDMI? It does seem odd though that the settings combine 2 different output methods in ONE option/setting. My older LG has them separate.

@td47 @td47 I don't know how all this got doubled up! ! But at first I did not have the optical audio out hook up I was just trying to get ARC to work. I do have it hooked up now so we can have sound while watch LG apps( Netflix and Amazon Prime). As you can see they are a combo choice but you have to have the Simplink on in order for the ARC to function. I just received the new HDMI cable this evening, Amazon's 2 day shipping took 4 days, so will start on it again tomorrow. I have downloaded the app to my phone which I like makes maneuvering the the Anthems menu easier. Why they would not have an on screen menu in a AVR at this price point who knows. But I digress will let you know if it works out.

Thanks for helping

@td47 I got it working! A new 4K Hdmi Premium cable did the trick. Its odd the other cable also states its 4K but it did not work. I am happy its going good now as I just received my SVS Atmos Height speakers today.

      I installed a few apps trying to get Casting to work that didn't work properly and I can't find anyway to uninstall them. My TV doesn't seem to have edit mode perhaps because I have had it a few years (pre-2018 some when- possibly its 10 years old or more as I can't remember when I got it). Anyone know how I can uninstall them?

      After updating my TV (OLED65GXPUA) on August 31, 2020 the HDMI-ARC volume support changed: pressing the volume up/down button once on the magic remote will continuously apply volume changes until the volume has reached the maximum or minimum value.  Prior to this update volume changes over the HDMI-ARC interface behaved as expected: one press of the remote button would apply one increment or decrement to the volume.  A Klipsch Bar 48 is attached to the TV over the HDMI-ARC interface.
      After the update the TV is running:  webOS TV version 5.1.1-3701, Software version 03.10.41.  I do not have the version information prior to the update.

      If anyone is still experiencing issues with the webOS Disney+ app (and I suspect many if not all of us still are) such as the lack of 4K support, 5.1 audio support, or as in my case with the 86UH9500, both, please see LG's response to my inquiry into these issues:
      We appreciate you for patiently coordinating with us regarding the current application status of your LG 86UH9500 TV, Xxxxxxx. It is our goal to ensure that you are able to utilize your LG product at its fullest potential so let us assist you with your inquiry today.

      In response to this, according to the specifications of the unit, the LG 86UH9500 TV has been designed with a 4K UHD and Surround Mode feature. However, if the Disney+ app is the only application that does not output surround sound, please be advised that both the content being played on the TV and the applications should also support this feature as well. This case on the capability and support made by the developers of the Disney+ Application needs to be raised directly to them so that they can make the necessary updates on the programming and utilize our TV’s 4K UHD and Surround Sound features that are already available in our OLED Television. You can reach Disney+ Support Line at 1-888-905-7888 for additional support and assistance.
      So, as expected, LG is pointing the finger at Disney to resolve these issues.  This makes sense as my inquires into the availability of the Disney+ app from LG before the launch directed me to reach out to Disney+ as they, not LG, are responsible for it. 
      So if any of you out there have Bob Iger on speed dial, can you give him a ring?
      Thanks!
      (PS yes, LG incorrectly identified the UH9500 as an OLED model when its an LCD, but I'll let it slide)

      In the last few days my LG TV OLED65B8PTA suddenly drops the volume significantly fleetingly every few minutes. 
       
      Am also hoping this isn't the start of the end of this massive investment I made a couple of years ago !!!
