When I connect from the Deezer app to the Chomecast in my Cambridge Audio CXNv2 streamer, the audio quality remains in the ‘wifi’ mode instead of the ‘Google Cast’ mode. Yet, if I connect to my separate Google ChromeCast Audio device, the app *does* switch correctly the streaming quality.

Why? Is the built-in Chromecast different?  I reallly would like the app to change streaming quality to Google Cast when connecting to my streamer’s Chromecast.

Thank you.
