ARC means Audio Return Channel, so you need this for a homecinema receiver or soundbar, not for the Apple TV. Something else must be going wrong.

please see the snaps above.

Soundbar is connected to ARC port on TV with tv audio is playing perfectly fine on the soundbar.

Apple TV is connected to HDMI port on the same TV but audio is not routed to the soundbar, hope it’s helpful.

let me know if I can sort this.

thanks

Hi @Nikhil_m 

Welcome to the Sonos Community!

I really don’t understand why your Apple TV is saying that it needs a HDMI-ARC connection - this literally makes no sense. Also, the TV should be in charge of where the audio is played, not the Apple TV. I recommend getting in touch with Apple support for assistance.

I hope this helps.

I have checked with Apple TV but to no avail.

don’t think this will work.

Hi @Nikhil_m 

The screenshots you posted - were those screens generated by your TV, or by your Apple TV?

Apple TV.

Nikhil.

Hi @Nikhil_m 

Thanks for that info - that’s what I suspected, but I’m still puzzled by what I see there.

What happens if you tell the Apple TV to use TV Speakers (the first option in first screenshot), then tell the TV to use the connected Sonos Arc (ARC output) in it’s own settings?

I hope this helps.

I tried manually selecting that option too, but apple TV is expecting some Dolby atmos output which it is not receiving on the HDMI port.

If you have some settings which i can use let me know, will try it out.

Thanks

Nikhil.

Hi @Nikhil_m 

OK, I think I have figured it out - I suspect that the Apple TV is trying to use AirPlay if you don’t select the TV Speakers, as it’s the only thing that makes any sense. Perhaps it’s wanting to receive TV audio (TV apps and broadcasted TV) via HDMI-ARC and then send via AirPlay to the speakers. This is not the way that you want this to work when using Sonos. Apple seems to expect you to be happy with stereo output unless you use their speakers (AirPlay only supports stereo audio when the output device is not manufactured by Apple).

Instead, the Apple TV should only be sending audio to the TV - the TV will send any and all audio to your Sonos Arc via its HDMI-ARC connection (no other port will work for your Sonos Arc, and TV’s generally only have one ARC port).

I think the following settings are what you want:

• Default audio output - TV Speakers
• Audio Return Channel - disabled/off (assuming that is an option)
• Temporary audio output - disabled/unselected

These are only guesses - if these settings do not work, or are not available, I can only suggest contacting Apple or looking on the Apple forums for answers.

I hope this helps.

@Nikhil_m 

It may help to get audio from the TV working through the Arc first, and when that works, try with the Apple TV.

That works fine.

@Nikhil_m 

Then that indicates that the Arc is working as expected, and that the TV settings are (probably) correct.

As far as I can tell, therefore, the settings I listed above should work. If they don’t, I really don’t know what will, but Apple should - just make it clear to them that you do not want to use AirPlay.

Does your TV support eARC? If so, the setting should be enabled on the TV. If not, I suspect you will need to tell the Apple TV to only output Dolby Digital 5.1, as Apple TVs will output formats that require eARC otherwise (Atmos (MAT) and Multichannel LPCM).

I hope this helps.

TV supports only ARC

@Nikhil_m

In that case, you will want to restrict Apple TV’s audio output format to Dolby Digital 5.1: “Settings > Video and Audio > Audio Format and turn on Change Format. From here, you can choose the following: Dolby Digital 5.1”.

I hope this helps.

I tried this also but still no audio.

Hi @Nikhil_m 

Does the Now Playing screen for the Arc in the Sonos app indicate anything at all when you should be getting Apple TV audio? If not, we’ve exhausted the advice I can give you.

I really do recommend that you contact Apple at this point - I have been given no training on Apple TV devices, and have never owned one. Please just be sure that they won’t try to get it working via AirPlay - don’t let them connect the Apple TV to the HDMI-ARC port on your TV!

One last thought - have you tried rebooting the Apple TV? If not, please do so.

I hope they are able to help you.

Lemme double check the app. Will update you by tomorrow 

I have rebooted Apple TV multiple times.

thanks

Nikhil 

I was able to make it work, thank you for all the excellent suggestions it really helped.

may god bless u

Hallo,

I have the same problem as you described, can you tell me how you solved the problem?

Regards Marvel

Hi Marvel,

as suggested by Corey, the following settings worked for me:

In that case, you will want to restrict Apple TV’s audio output format to Dolby Digital 5.1: “Settings > Video and Audio > Audio Format and turn on Change Format. From here, you can choose the following: Dolby Digital 5.1”.

Regards, Nikhil.

Thanks for the info. I noticed that Sonos advised you to do a reboot of the Apple tv. Did you do a reset or a restart?

Yes I did a reboot/reset

Ok, I will give it a go. The strange thing is that I have problems since last year and before that it just worked perfectly. Very strange and know I hope that it finally wil work as before.
