Hi guys. 
Recently bought a new LG G1 and I love it, it replaced my CX which had a faulty panel however the G1 will not pass LPCM or Atmos to the Sonos Via E-arc Passthrough. If I put it the LG on Auto I get Dolby Atmos but no LPCM for my Switch, Apple TV and PS5. With the CX it at least passed it through, although always in LPCM 7.1 which I know they intend to fix. If I try in my Xbox to put LPCM or Atmos on it says your receiver doesn’t support this format. Is it because the TV is so new the Arc and it aren’t communicating properly. I’m really disappointed and I love my Arc and my G1 but would like my sound to be accurate. 
Any ideas or is this a known problem?

Thank you

Try setting your Xbox audio to be pass-thru? Have you done this (from rtings):

 

I can get my Xbox to do Atmos with the Auto setting on the tv. I don’t mind that so much but the switch only does LPCM and the Apple TV’s best audio is LPCM. It used to work ok(ish) on the CX and pushed LPCM but using pass-through it just won’t do it. All my settings are correct but like I say it’s like the tv and Sonos aren’t communicating what each other can do over EDID properly.

It could just be a bug in LGs firmware. You would think that after the fiascos with last years models’ HDMI 2.1 support (Samsung also sharing the blame here) they would have figured this out by now.

You are probably right. E-arc seems to be something a lot of manufactures can’t seem to sort out.
