No audio on the external HDMI ARC device from LG CX


SB Raja

Question

Hi,

I have a Sony sound bar connected to my LG OLED CX via eARC. It was working fine. One day suddenly the sound bar stopped responding to the incoming audio from the TV. I tried all the ways - (PCM, Auto, Pass Through), TV reset, Additional settings eARC (on/off). But nothing worked. Escalated it to the LG CC. And the LG service representative advises me to change the mother board of the TV. I am wondering what went wrong with my 9 months old TV. Though it is still under warranty I dont want to go for a change of a component (if there is a work around). Sound bar is working perfectly with all other external devices. Awaiting for a solution or atleast a valid reason.

      I wish I could control the volume of my LG TV 65NANO96SNA (webOS 4.50.71) using Apple TV 4K 3rd Generation (tvOS 17.3) with HDMI CEC (Belkin AV10176bt2M-BLK cable). The Apple TV has it on Settings, however, the TV does not respond to it. Turn on/off works. Volume control only works with IR. Could we prepare an update to support and fix it?

      I have a NANO91ANA LG TV connected via HDMI to a Yamaha RX-V677 Receiver. Normally when I turn the TV on it also turns the receiver on and I can control volume via the LG remote, whether it is an app on the TV or from another device connected to my receiver (Apple TV or cable box). Now the receiver is not turning on and ARC audio is not working. I think there may have been a software update the other day, but I'm not sure. However, everything was working properly until last night. The last time this happened it seemed to correct itself (it seems to be kind of sporadic), but this time it did not. I do not know what to do to correct this, but it is a major pain as I'm now having to deal with 4 remotes, plus I can't get sound out of my surround speakers when using an app on the TV.  Any suggestions would be appreciated.

      I have been trying to get my Google Home and Nest Audio Speakers to turn my LG OLED65C24LA TV on and off.   I have linked ThinQ to Google Home but it still wouldn't work.  So plan B was to get a Chromecast to do this one simple voice activated request....I have no intentions of using Chromecast for anything else!
      So this actually does work, however, when asking it to turn the TV on, it defaults to the home page of Chromecast TV, I want it to just open to my normal TV system, which is Sky Q.  Ideally, I would like to disconnect the Chromecast and just get Google Home and ThinQ to do this !!
      I have checked every setting and trawled the internet for a solution.  I've posted on the AV Forum in the UK and the Google Forum and I'm waiting on a call back from LG Support UK.
      I expected this to be a VERY simple task !!
      Can anyone help with this ?
