Sonos with Yamaha receiver and streaming from laptop

I have an LG projector and a Yamaha receiver, Sonos beam and sub, and wired in surround backs wired to my sonos amp. I typically stream stuff off my laptop through the yamaha receiver which then feeds the video to the projector. The receiver is a TSR-7850 and has an HDMI ARC. I can get picture going from my laptop to my projector but I can’t get corresponding sound through the receiver to my beam and subsequently throughout the surround sound sonos setup. What am I doing wrong?

    Completely understand. ;)

    There are two places I’d be looking at in your system. And I’m not near my Win10 machine to double check for accuracy, so I’ll be somewhat vague, and trust you to poke around and find these things and maybe learn where things are, and figure out where I am just some looney on the inter webs.

    The first place is in the app you’re using to play the files. There should be somewhere in the app where you can control what kind of audio is being sent out.

    The second place is in the Win 10 settings for either Audio or perhaps Video, where you are able to configure the output of the HDMI output, and define what kind of audio is included with the video stream. 

    Look around for those two settings. I think if the first works, you wouldn’t have to worry about the second...but only if that player app is the only one you ever use to play a video. The latter, being a full system setting, is more likely to help in future use.

    I’ve got the ability to sync up sound/video in either the receiver or the Nvidia shield (can’t remember which) by delaying one of the feeds, so I think that would be solved but you’re right, the whole point of this is to get surround sound so if I can only do stereo with a Sonos Connect, then this is moot.

    mykasd,

    The Connect will only provide Stereo and if you delay the audio on your 3rd party Receiver or Shield, it still means the video out on the projector will be ahead of the audio… it maybe okay, no echo etc; but I think it would be noticeable when watching people speaking on screen. It really needs the Beam to do this, as it supports 5.1 audio, plus the delay is minimal (think of it as not buffering the audio) and it communicates with its ‘bonded’ (not 'grouped') surrounds over a faster 5ghz ad-hoc Network… less chance of lip-sync issues with that device, but appreciate you are having some issues using that product with your Yamaha Receiver involved in the mix.

    @Ken_Griffiths I tried everything I could without the Yamaha in the mix: audio extractor, HDMI splitter, using another Tv as a switch basically. Nothing could get the Beam to accept the sound file while the projector was displaying picture. I’m baffled. Had a lot of smart people offering advice on what to do and we couldn’t get it set up so I had to buy a set of wired speakers for the home theater. Unfortunate.

    Yes, I have been following this thread.. it’s rather baffling that you haven’t got things to work. I’m sure you have double-checked your device Settings, but 'on paper’ I would have thought it should have worked with an audio extractor/splitter by simply taking the Dolby Digital 5.1 audio from the Shield direct to the Beam and it’s surrounds ... and then splitting the video off to your Projector.

    Adding the Yamaha Receiver into the mix adds a little complexity  … like @Buzz mentioned earlier, I think the Projector and EDID might be where the problem lies for you and my thought was to perhaps run a 'playing‘ 5.1 audio source to the Beam from the Shield using an HDMI-ARC connection (not Optical) and then introduce the projector connection into the setup afterwards, once you have confirmed the playing audio is correctly being output ....the idea being that the initial HDMI-ARC handshake between the Shield and Beam sets up the Dolby surround audio and by adding the Projector afterwards it will (hopefully) not alter the original handshake … but not sure if that would work?

    I 'think' you can purchase EDID adapters to force the correct HDMI handshake required, but it’s not something I have ever used myself, personally speaking.

    Sometimes unplugging an HDMI cable for a second will trigger the EDID to successfully renegotiate the setup.
