eARC Extender - Home Theater System

Hello Sonos Community. 

 

This is my first post, and its a question I am hoping someone else has solved already. 

 

My system:

Arc Sound Bar

Era 300 x 2

Gen 3 Sub

Apple TV 4K

Sony Bravia 8 (K-77XR80)

 

I am looking to use the eARC HDMI port on my TV with my Apple TV, however from what I understand I have to use that port for my Sonos sound system as well.  Meaning I have one port, and I need two on the TV. Does any one know of or can recommend an eARC Extender(Does that exists)?  I am hoping there is such a thing so I can plug the Apple TV HDMI cable and the Sonos HDMI cable into the same eARC port on the Sony TV.

I am wanting to get the most from the Apple TV as far as sound / video goes and I cannot do that if the Sonos System is using the only eARC port on the TV.

 

Thoughts?

 

Thanks,

Daze (Jeff)

Apple TV to any HDMI.

Arc to the eARC port. Your Apple TV does NOT need this port.

Ensure Dolby Atmos is on in your Apple TV sound settings, and that you are playing Dolby Atmos content (ensure your subscriptions have that).

Ensure you have Passthrough activated in your TV sound output settings so the Apple TV signal isn’t processed by the TV.

Just curious…

You started your post 20 hrs ago and received your answer 20 hrs ago. Yet still you had to be convinced by 6 different members that whatever you were thinking was wrong. Why didn’t you just plug the ATV into an HDMI port 19 hrs ago to try what was suggested without all the back and forth? Seems you wasted a lot of your time and enjoyment of your ATV.

 

Your comment comes off as unnecessary and condescending. How I choose to troubleshoot something with my equipment and my time is entirely up to me. I posted in good faith to gather different perspectives before taking action—something forums are meant for. If that bothers you, you’re free to scroll past. No need to police how others go about solving their own issues.

Bye Bye,
