This morning I got my main library set up to stream when I'm out of the house. Overall my experience during my two 30 minute drives was excellent. I was really impressed with how CarPlay integrated what JRemote was playing, including artwork. I had zero audio issues as I streamed 44.1 24 bit FLAC from my house.
On the ride home I poked around more in the app. I noticed the Cloudplay radio stations were there and picked one...nothing. The link blinked when pressed, but no music and no recognition in the player portion of the app that I had selected anything. I tried a few more stations.. same thing.
Imagine my surprise when I got home and my studio system was cranking Radio Paradise
What was more interesting was that no where in Media Center could I find any evidence of what was happening. The app showed that nothing was playing on my one and only Zone. In fact, clicking on Paradise Radio started a second instance of it while the first was still playing! The only thing I could do was quit.
I have since replicated this situation. I kept my phone's wifi off and tried streaming again. Anything in my library streams to the phone as expected, but if I start up a radio station... it starts playing on my home system with no evidence in MC that anything is taking place.
