As of yesterday, my LG remote no longer changes the volume on my Uniti Atom connected to my LG TV by HMDI ARC.
The remote is definitely sending a signal as it changes the volume normally when the TV is set to use its internal speakers.
I presume either the TV or the Atom has had a software update?
Anyone have any idea how to get it working again
Thanks, Jim.
Try powering off both items (unplug from wall) what for a few minutes. Also unplug and re-plug the HDMI connection. The re-plug and power up.
There are Audio settings in the LG which need to be set, it may be defaulting to internal speakers or something else.
Don’t know what model you have but press settings, select audio and choose hdmi arc from the scrolling menu.
Now working again.
I followed Richard’s advice, and powered everything off for a couple of minutes. But when I switched it back on, I also installed the new firmware. So now I don’t know whether it was the power down that fixed it, or the update.
Either way, for now, it’s working.
Thanks for the advice, both.
Jim.
Since it worked for a while and suddenly stopped (before you updated), there’s a good chance the devices “got confused” or “lost sync”.
I think that’s what the “reboot” of each device can help resolve, by resetting them to a “default good state”. (Just like “confused” computers, phones, etc. - there’s a lot of software and firmware in these devices these days.)
