Pressing Standby in the app doesn't seem to work. If I'm listening to either Deezer or TuneIn Radio and press the Standby button from the home screen, the button will flash red, and the music will pause for a second or two and then continue to play. If I pause the music and press Standby, the speaker is muted (the LED blinks white and the volume control in the app has the muted icon).
