When I open the Roon Essentials app via my Iphone 6, this instantly finds the Elac Discovery, I can operate all settings without any problem.
In the attic, in my home cinema, I connected the Elac Discovery Analogue and Digital to my Pioneer SC-LX87.
Downstairs in the living room I have an Airport Express (Gen. 2 upgrade to Airplay 2) which is connected to my Denon AVR via analog cable.
So the zones are:
When I switch between zones this works very well but when I switch to the Airport Express zone and push the start button, it immediately goes into pause, pushed back to play a few times but immediately back in pause!
I am using a wireless system from Devolo (1200 + wifi) and first thought of the dual band of 2.4GHz and 5GHz.
I have tried all the settings: both bands, only the 2.4GHZ and only the 5 GHZ, this does not matter.
The Airport Express is recognized but I can not play it.
With Itunes I also tried this via the streaming button, and there I can choose again between the Pioneer SC-LX87 and the Airport Express. If I select the Airport Express it will play without any problems on the Airplay Express. (Via aux in from my Denon amplifier)
