Have a brand new U8g and nothing else but Sonos Arc attached via HDMI eARC. S2 App shows checkmark for HDMI ARC connection, but the audio test fails. Both U8g and Sonos Arc firmwares are updated.
Optical works, but I want sound with ATMOS via eARC.
Also the U8g menu items for selecting ARC output are grayed out in the tv settings. Can only select tv speaker as output. It seems there may be bad CEC communication as I noticed if I disable CEC on U8g that the ARC output option can be selected, but it goes right back to grayed out after changing menus.
Any ideas would be appreciated.
Would a CEC Less adapter force the tv to be able to use ARC for audio out?
