ARC not working (C9)
Hi, recently I bought LG OLED C9 together with Marantz SR5013 receiver. I wasn't able to set ARC working so I returned Marantz and gave a chance to new Onkyo TX-NR696.
Now ARC is working but only if I have one HDMI cable connected, the main one that goes from Onkyo HDMI ARC port (out) to LG HDMI 2 port (ARC).
If I connect one additional HDMI cable to AV receiver, for example PS4 HDMI to GAME port of the AV receiver, ARC immediately stops working and TV switches sound from the 5.1 speakers to TV speakers. When I plug out the HDMI cable from GAME port after few seconds ARC begins to function and sound comes out from 5.1 speakers. It happens even if PS4 is in stand-by mode.
To make it more complicated, if I plug directly HDMI cable from PS4 to TV HDMI1 port (so not to go via AV receiver) the same thing happens and ARC stops working so this must be due to LG. This is strange and I cant' find logic behind this. Where's the catch and is there something that I could try? Currently I'm using 1.4 HDMI cables. I also tried with 2.0 cable (cheap model) and the problem was the same.
LG C9 is too expensive TV to have such a problematic ARC.
