Question

No dialog through Arc from Apple TV 4K

Hi guys,

Weird issue: I’ve my LG C9 TV set to passthrough/eARC, and Dolby Atmos works just fine. However, when I play non-Atmos content (5.1) I can hear no dialog track from the movie, and the Sonos App shows Stereo 2.0 as played content.

Turning off eARC or changing from passthrough to Auto or PCM makes 5.1 content hearable, but only at Stereo 2.0 and not 5.1

This is only affected by content from Apple TV. Native TV apps are playing correct sound formats via Arc

Any help would be most appreciated.

Just to let you about your concern that if it’s only not working with Apple TV, maybe it’s something to do with its settings. You may need to double-check it or check it with Apple as well.

Thanks for getting back to me, after some further research it appears that it’s the issue with apple outputting LPCM audio, LG TV passing it through to Sonos Arc, and that one doesn’t support the LPCM :( I know you guys are planning on this support, maybe you could kindly check and give us an indication on when can we expect it? I know many people on this forum are awaiting it.

Thank you!

Is this included in the 12.1 update?

Hi @Krishma M I have been following this topic closely, on this thread and others, and I have been reluctant to make the Arc purchase based on its unreliability with the ATV.

Any updates on this front?
