When you run bubble upnp app on your mobile you can choose the upnp server which is sonology my case and then you can also choose the renderer which is moode on Raspberry Pi. The only physical connection the needs to be done is the Raspberry DAC which in turn will be connected to the amplifier and the speakers. And all the three can communicate with each other over WiFi. All the three components the server, the controller and renderer should be on the same home LAN network. Raspberry Pi is acting as a upnp renderer. My mobile running an app called bubble upnp acts as a controller that would read the music from the server and then push it to the raspberry pi. In my example my synology server acts as upnp server which stores all the music. Upnp renderer is actually the player that actually plays the song connected to the amp and speakers. Control point Can be your mobile, tablet with an app to actually read the data from the u p NP server and then play it on to the renderer. U p NP server reads the music and makes it available for the upnp controll point to pass the data to the renderer. UPP server acts as a place that stores the music any media server can act as UPNP server. second is UPnP renderer and third is the UPnP control point. UPnP has three components to work with, first is UPnP server. For that you need to understand how u p NP protocol works.

But since the 3.5 mm jack is not a good sound output it is always preferred to have a USB DAC connected to the USB port of pi and then connected to AMP which in turn are connected to the speakers. Click to expand.Even if you do not have DAc you can still connect your pi to amp.
