HDMI/ARC completely dead after update to

[conrad]

After my LGOLED55C7 updated to 04.70.85 I have l;ost all sound through ARC.

I have an Arcam AVR550 receiver which works for everything else and used to work perfectly (even with the latest Arcam update that provided Dolby Digital +).

Unfortunately after the TV updated to 04.70.85 I have lost all sound over ARC. The reciever switches to RC as normal when, for example, Netflix is started, It shows Dolby Digital + is being transmitted, but there is NO SOUND.

Any clues?

I have factory reset both the TV and the receiver :-(

Exactly the same situation here 😒

Model 55E7N, also factory reset and nothing works through arc

Before the update everything was fine

Now just tv speaker and no sound bar 😢

Today i called with LG customer service

09006533543

from the netherlands so not sure if it works outside the netherlands

I told him wat my problem was, and i had to email him pictures of all the data stored onder about my tv

such as software etc

Here i use a teufel c11bs soundbar and works through 3.5 jack and works through Fiber

but not under hdmi what ever i try

He is coming back to me

we also checked that 04.70.85 is the latest software avalaible

Even on the website as ota now newer avalaible

I can also confirm this issue with my LG 86SJ957V. I was using Denon AVR-X1400H and my ARC was working without any problem.

After the 04.70.85 firmware update, no sound whatsoever. When I select the ARC/Hdmi in the TV it doesn't even turn on the receiver.

Should I wait for the next firmware or should I buy a media player?

Same here, I tweeted at @LGUSSupport but no big hopes: "Did something happen with a recent webOS update (04.71.00)? My OLED65C7P no longer outputs sound to my LG SJ9 soundbar in Optical/HDMI ARC mode. SIMPLINK is on, HDMI cable hasn't moved, had worked like a charm for a year+, but no sound as of a few days ago"
