I have recently got an S95B QD-OLED and I'm having a problem with the eARC.
I have it connected to a HW-Q90R soundbar via HDMI eARC port and have a Sky Q box and Xbox Series X connected directly to the TV.
Whenever I press the guide button on the Series X controller or Sky Q remote the sound drops out and the soundbar flashes eARC after reconnecting.
I never had these issues on my old Q95T with any devices.
If I change the output to the soundbar to WiFi it works as it always did before.
Starting to think this is a faulty HDMI port as I cannot find anyone on S95B owners forums having the same issue.
Anyone here experienced this?
