Dolby Atmos Audio out

Question

I have connected by Apple TV on my LG C9 OLED TV. It is connected via HDMI. The TV is connected to Onkyo AV via ARC. While playing a Dolby Atmos enables movie, the AV receiver does not recongnize the output. But while connected the Apple TV directly to the AV, Dolby Atmos gets enabled. Though the HDMI Audio out is set to Bitstream why the AV unable to play Dolby Atmos. Please let me know if I need to make any adjustment in the settings.

Depends on the implementation of ARC some only output Dolby digital via this connection better to use optical connection.good article on CNet about this. Not all devices implement ARC for high def audio.

Have you enabled Dolby Digital Plus in the TVs sound settings? It is essential to have this on to pass Atmos via ARC or eARC to a soundbar or processor.

      I have two LG OLEDs.  I have given each a name in the WebOS.  Occasionally when a TV is powered on, I am first requested to enter the TV name along with the dialog to enter text with  the on screen keyboard.  I can enter anything and it is accepted and I get past that screen and then normal operation follows.  This happens on both TVs albeit only occasionally.   It is a real nuisance when this happens and I see no need for this.
      Has anyone else experienced this and if so, is there a solution to disable this behavior?  Is there some setting that I have missed?
      Thanks,
      Bobby

      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.

      I recently updated the firmware on my  LG43UH610V.  Now I constantly get "Wired Lan cable disconnected" / "Wired network is connected" messages even while watching a video file from my NAS. The TV is connected and using the network while getting these messages. It has always been on a fixed IP address on the LAN.
