no sounds output on Sony KDL-40EX720

I just bought a Sonos Arc soundbar. I connected seamlessly to the network. When I connect it to the TV, the TV says “Sound System Active and switches to that output, but no sound comes out of the soundbar. The TV is approximately from 2011, it has an HDMI Arc Port, it does have Sonos Arc listed among HDMI devices.

It has the latest firmware form 2014, Sonos has the latest update too. I tried the disconnect/reconnect steps, set the audio format to PCM. I normally use an android TV box, but just to make sure that wasn’t the culprit, I disconnected it and plugged the antenna cable straight into the TV, still no luck.

The connection within the Sonos app to the TV fails, which is probably the reason for the issue but I don’t know how to fix that...

Any thoughts on what else I can try?

Thanks,

Gaetano.

The TV has the latest software and the optical cable does not fit in the optical socket of the TV, it won’t get completely inside. Are there different format for optical connections?

It should fit. Be sure you are inserting it correctly. Make sure there isn’t a small cap covering the lens of the optical connection on the adaptor.

I tried every angle, I can see a red light. There was initially some kind of membrane or cover but it came off

Can you post a photo of the optical port on your TV?

OK, I was looking for a cap on the TV socket but there was one on the cable… I was able to connect it through optical.

It said this was for initial setup only on the box. What do I do now? do I disconnect it or leave the optical connection on ans the ongoing connection?

Turn off “Control for HDMI” on your TV.

Set “HDMI/DVI Audio Source” in your TV settings to “Auto”.

Run “TV Setup” in the Sonos app and follow the instructions and connect the Arc to your TV with the optical adaptor.

    I have done that and it is connected, so whats next? The box for the optical adapter says it's only for the initial setup. It is not clear whether i should now try the hdmi arc port.

    Keep the Arc connected to the TV with the optical adaptor. Don’t use the HDMI port. Do you hear any audio from the Arc?

    yes, it’s working fine on Optical, but the app said it would not support Atmos on Optical. Some sound is better than no sound, but part of the reason I got the Sonos over the Bose 700 was the support for Atmos...

    Even if the Arc worked with your TV’s HDMI port, you still wouldn’t be able to get Dolby Atmos audio with your older TV.

    Your TV is from 2011. I’m 99.99% sure it won’t pass through Dolby Atmos audio from any internal apps or external devices.

    If your HDMI ARC port actually worked, I would have recommended getting the HDFury Arcana if you want Dolby Atmos audio using your current TV. https://hdfury.com/product/4k-arcana-18gbps/
