Onkyo’s receivers will work with Sonos, thanks to upcoming June firmware update

Works with Sonos sends them over the network connection.
So, not via the line in autoplay feature; will the wired line in be eliminated then, with music signals also passing wirelessly?

That was also my initial thought when I bought Sonos Connect. Doesn`t work. The wake up & auto input selection seems only to work over HDMI (CEC). My Onkyo is Ethernet connected and I can wake it up through the Onkyo App and also select Sonos Connect/Coaxial digital input over the Onkyo App and then play music through Sonos. So that makes the Onkyo App more or less take over the remote control functionality, nothing more, nothing less. So both powering on and selecting input are necessary steps at this time to play through Sonos Connect which should be solved by the update (I hope).

My guess is that any receiver that can be controlled through the Onkyo app will also be controllable through the Sonos app. I'm sure there are some different protocols involved, but it's pretty much the same process for control. What would disappointing is the method of control for Sonos requires that your Onkyo app be running in the background. In other words, Sonos doesn't talk to your receiver directly, but through the existin Onkyo app. That would be ok in a lot of situations, could cause some automation processes to fail, if your phone isn't on the wifi and connected.

I hadn't thought about the possibility of waking the receiver through RCA inputs. I know Sonos does this, but I wasn't aware of it as something other AV equipment does. I really doubt that's going to be used though, as it seems like the major requirement for recievers is to have access to wifi.

Although I have 2 connects that I never use and decided to hold onto, so it doesn't effect me, I am hoping that the CONNECT has a price drop soon, I would think that the price of the connect is going to keep a lot of consumers from adding on Sonos to their receiver purchase, especially when they aren't existing Sonos customers. But if the device is around $150 (the price of PLAY:1), then I can see customers really tempted since you're going to access to all that streaming, good app control, AND potentially voice control. I can also see a slight price drop on the receivers too, since they don't need to have streaming access built in anymore.

According to the Onkyo website, it specifically states that RCA wires will be required. So no, the audio will not pass wireless. That is to be expected though, as sending the audio wireless would surely require more dev work and hardware requirements, not to mention exposing/sharing some of Sonos multiroom tech to Onkyo.

Agree that the audio will need the cable from Sonos Connect out to the line in of the Onkyo but I think (and hope :8) that this will not be limited to the RCA but also applies to the SPDIF outputs (coaxial & optical) of the Sonos Connect. I assume the website is only mentioning RCA because Sonos provides this cable with the Connect. And...I never got any coaxial or optical cable from them with my Connect. 😃

No. The music sources will remain as is, the control commands will be sent over the network connection, just like they are now from the controller to the Connect. The Works with Sonos API will route the ones meant for Onkyo to the Onkyo and the Onkyo will translate perform them just as if the Onkyo app sent them.
