Sonos Connect + Denon AVR

@AmosT, 
Unfortunately it’s not a very helpful screenshot as it shows the (disconnected) line-in settings, rather than the Connects line-out.

You first need to play an audio source to the Connect ‘room’ using the Sonos App (eg.Tune-In radio or Spotify etc.) Ensure you can see it actually playing in the Sonos App (now playing screen) - check/raise its volume level to approx. 50% and then go to your Denon Amp and select the CD input, as your playing source. Also turn up the Denon’s volume level and then see if you hear anything playing. 

Sorry about that.

So I played a song from the Sonos App, put the volume to 50%, selected the right channel on my Denon, turned the volume up, even to the maximum but nothing happened.

The Denon and the speakers usually work as my TV and Apple TV, linked to the Denon with HDMI all work good.

I will try the connexion through optic tomorrow and let you know !

Thanks again for your time !

Try switching the Sonos Connect line-out level between ‘variable’ and ‘fixed’ and see if that solves the issue.
 

Note do not have the Denon volume-level set too high initially as the Sonos ‘fixed’ volume level is 100% and do not want to blast out the audio and perhaps make you jump… so increase the Denon volume from a low level - you could maybe also go onto try one of your other Denon audio inputs aswell. (DVD etc.)

I note too @AmosT, that aswell as analog audio inputs there are similarly named HDMI inputs - so just ensure you are selecting the correct audio ‘input’ in your Denon source playback selection options.

Also, make sure that the RCA plugs are fully seated in CONNECT’s jacks. Sometimes more force is required than expected and the plugs are not inserted far enough to make contact.

Hi

You've gotten great advice thus far. Just going to add my voice and hope it doesn’t confuse you 🙂

These are the basic connections (in layman speak) for the Sonos Connect of which there are two Options.

Option 1

The Sonos Connect can SEND audio selected via the Sonos app via a streaming service or music downloaded to your device in the following manner:

• Sonos Connect RCA-Out to an available RCA-In on your Denon AMP with audio heard through its speakers

Option 2

The Sonos Connect can RECEIVE audio selected from a source on your Denon (such as a Turntable, Radio station, CD or Tape deck) in the following manner:

• Sonos Connect RCA-In to and available RCA-Out on your Denon and that audio can be heard through Sonos speakers.

The aforementioned connections can be setup simultaneously to allow you the flexibility to choose how you want to listen to audio using the Sonos Connect. 

The link below will guide you through setting up your Sonos Connect

This link will guide you through steps to get audio from a Denon source component discussed in Option 2 above. NOTE: The article refers to the Sonos Port that replaced the Sonos Connect; however the steps are the same. The article makes mention of that fact as well.

Good morning,

Many thanks again for your interest and help !

To answer to @AjTrek1, i want to the Sonos Connect to send sound to my Denon (Option 1).

Unfortunately I have tried to connect the Sonos to every audio inputs of the Denon, but it only works on the Phono one (with a very bad quality audio). I have also tried to connect it through an optical audio cable, but the result is the same : no audio. 

I don’t know if the problem comes from the Sonos Connect (maybe the audio compression ?) or from the Denon…

I would maybe try playing a different device to the inputs on you Denon Receiver, an MP3 player or mobile phone etc; and see if those play when you select the correct input - at least that may help you to narrow things down a bit more.

Poor audio quality from Phono confirms that there is output from CONNECT. Only a turntable (without a preamp) will sound correct as the input for Phono.

Some receivers provide options to reassign analog inputs, perhaps allowing the input to pair with a video input. While I don’t know why all analog inputs would be reassigned, this would be something to check in the receiver setup. Testing this hypothesis is tricky because it is common to ignore audio assigned to a video input unless video is actually present.

Always check for silly things, such as CONNECT being muted or at minimum Volume and that the RCA plugs are fully seated.

Hello !

Thanks to your comments I managed to solve the problem with a reset of the parameters of the Denon ampli. The analogical entries input were not activated.

Many thanks for the help !
