apple tv 4K says not available for ARC

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

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.

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.

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