Sonos Surround Sound with Sony Bravia

OK, so this TV has ARC, and you've connected the Beam to the HDMI 1 port on the TV. When you look in the controller, the room name for the Beam shows (+LS +RS), correct?

The HDMI-ARC will set the TV's audio settings for you, which is probably why you can't see a setting. It's detected that there's a connected device, and will switch the TV's audio settings to the required settings. That's what HDMI-CEC/ARC does.

If all of this is true, then your issue is the signal being sent in to the TV set, It needs to be a Dolby Digital signal. If you're using a cable box or satellite box, you'll need to go in to the audio settings on it, and make sure that it's sending a Dolby Digital signal through to the TV. Then put on a recent movie, which will be much more likely to "tickle" the surrounds than a talking head show like the news.

For those playing along at home, here's the link to the manual: https://www.sony.co.uk/electronics/support/res/manuals/4584/45846441M.pdf

Is it not outputting surround? Go to sonos app....settings...about my sonos and look to see if input shows stereo or 5.1

Thanks a million Bruce

All the above sounds correct, I have the Beam connected to the ARC HDMI slot, and my main box would be a Mag 254, so you are saying the input from that is the problem?

I also have a PS4 connected directly to the TV, so surely if I played a Blu Ray on that, I should hear some activivity on the surrounds?

It says @stereo there at the moment alright

just new to all this by the way, so thanks !

So your using PS4 - have you confirmed the PS4 is set to output dolby digital?

as far as audio settings on tv

Home>settings>TV>sound

OK so PS4 is perfect - thanks!

Im trying to sort the Mag 254 now, but seems tricky to get that to output Dolby

You may need to get in touch with the cable company (assuming that a Mag 254 is a cable box?) Or find a manual online.

also on cable - some channels only broadcast stereo so you may need to be sure on a station that has DD 5.1
