ARC not Fnctioning

Post by Sandy B » Thu Dec 26, 2019 12:32

I am trying to connect a LG NB4540 sound bar to a Dick Smith GE6992 TV, with very limited (no) success.

I do not get any audio when connected to the TV's HDMI ARC, yet something is connecting as I am able to adjust the sound bar volume via the TV remote with say "78 Power Amplifier" appearing on the TV. There is nothing wrong with the HDMI cable as I have tried 2 cables and both work with the sound bar when attached to my LG TV. I have CEC switched on and SPDIF set to PCM but again no audio. When I connect a DP-P2 via the sound bar to HDMI 2, I still get "78 Power Amplifier" on the TV, in this configuration I get the P2 "audio. With this connection I can get TV audio from the TV's speakers with the sound bar off, however with the sound bar on I get 1 second of sound and 5 seconds of mute.

Anybody got any ideas.

I couldn't get ARC working from my LG TV to my Sony HT system, either (model numbers in the signature block).
