Hi
Since i bought my LG OLED c1, impossible for me to get sonos arc work properly when i open the TV ( i have to revert to internal speakers then select hdmi arc to have the sound go back)
But the worse is that i couldn't have earc: when i toggle earc in the menu it reverts automatically to internal TV speakers
I'm using a ultra Hugh speed hdmi câble certifiée between the two devices, sonos arc and LG c1 up to date, i've tried all the settings possible on the TV ( passtrough, auto, bitstream, simplink, hdmi deep color etc)
Is it sonos related?
