While stream recovers the tray icon state is off
When there is a network failure the stream recovers but the tray icon state is off during the recovery. That means during the recovery one can not stop the stream or change to another one.
Sometimes a stream fails right after the connection and you can hear jagged sound when it is repeatedly on and off. To turn the stream off permanently one have to hunt for the time when it is on or try to change the station when it is off and wait for a connection failure.
