Panasonic VT60 ARC | Sonos Arc | Immersive sound

Hello community!

I have just purchased my first Sonos setup:

2 x Sonos One

1 x Sonos Sub gen 3

1 x Sonos Arc

My tv is a Panasonic VT60 55” with 1 ARC HDMI port.

1 x Apple TV 4K

I did a complete setup yesterday really exited to experience the setup.

But something did not sound rigth and when digging a bit i understand my Arc plays Stereo 2.0. Been reading on the forum here and see there is an issue with LPCM or whatever it’s called and Sonos Arc not properly handling it.

sorry, my sound skills are not all there yet 😳🤓

Then i did some more digging.

Changed audio format from Auto on ATV to 5.1, but then i loose audio on Sonos Arc.

Setting audio format back to Auto again and i go back to having stereo 2.0 on the Arc.

Then i discovered something…

Started Netflix on my ATV and started an episode of Star Trek Discovery.

I pulled down the dropdown menu on ATV and see that i can select where to direct my audio, either HDMI or Airplay.

so i tried using Airplay to direct the sound from ATV directly to the Sonos Arc while passing video through HDMI.

sound suddenly sounded amazing but i have no idea of what format is being played.. it does not show under My system in Sonos2 app.

how can i identify what kind of sound is being played via Airplay with this setup??

Hi @K.Tryggeseth.

Thanks for reaching out and for your detailed post outlining your concern, I’d be glad to help and get this figured out.

1. Please refer to this article that outlines the main factors to determine if your Sonos Arc can play Dolby Atmos audio.

To sum it up, every ingredient in your home theater setup has to support Dolby Atmos, to get Dolby Atmos on Sonos Arc.

NOTE: Most Dolby Atmos audio can be played through HDMI-ARC using the Dolby Digital Plus (DD+) codec.

HDMI-eARC is required to play lossless Dolby Atmos audio using the Dolby TrueHD codec.

2. The TV where you’re playing it on has to be able to decode Dolby Atmos or pass it along to a Dolby Atmos-capable sound system without altering it. This is known as “pass-through.” In most cases, the TV will re-encode the audio to Dolby Digital 5.1.

3. Apple TV 4K automatically plays sound in the highest quality that’s supported by your home theater system setup, and available with content that you watch. If your home theater system doesn't support the audio format that Apple TV automatically selects, you can manually change the audio format on Apple TV. Go to Settings > Video and Audio > Audio Format and turn on Change Format.

You can choose between the following:

Dolby Digital 5.1
Stereo
