Audio Devices (Specify what device you’re using and its connection type - USB/HDMI/ect.)
My main endpoint is a iPhone 5S, connected to CCK USB3.0 with constant USB power and a DragonFly Red wired to my active speakers. There is also a PC (wired network on same switch as the AP-AC-PRO AP) that has a Audioengine D1 connected through TOSlink for data and powered with USB form the pc’s mobo and an iPad pro 9,7" (occasional endpoint, sometimes used as remote).
Description Of Issue
When I fire up Roon remote on my iPhone XS Max, It usually works fine, connects to the core well and I can start playing whatever I want… If the iPhone goes to sleep, and I reactivate the Roon app later (often to adjust the volume), the Roon app on the iPhone more often than not cannot connect to the core and suggests to look for another one. If I quit the app (swipe up), wait 2-3 seconds and reopen the app it usually works fine…
The iPhone is has excellent signal on the 5ghz band, does everything else great, but “waking” the Roon app shortly after i’ve used it into the same screen. This problem doesn’t seem to happen (or at least not to I degree that I can remember) when I occasionally use my iPad (pro 9,7" model) in the same location for the same purpose…
