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 :-(

After my TV update to 04.70.85 (UK) I lost HDMI ARC. How did you solve your problem?
