I have noticed what I think is a new form of misbehavior by the audio system since the installation of the latest software update (2018.21.9 75bdbc11) a few days ago. The misbehavior occurs with the audio system playing a particular channel of streaming music. The song ends. It cues up the next song and plays perhaps one or two seconds of it and then stops abruptly. The screen displays the pause symbol, implying that it is playing the music. But in fact, it is not playing any music, and nothing further happens. If I hit the pause button and then hit play, in an attempt to prompt the music to play, the audio system starts to play a different channel. In my case, it has every time played a certain podcast that is positioned adjacent to the one that is being played on my list of channels at the bottom of the screen. I haven't done enough testing to determine if the position is a coincidence or if it actually determines what happens. But in any case, it starts playing the podcast, but continues to display the song and the channel that was queued up but never played. So, the screen display is inconsistent with the actual behavior. If I force the audio system to use a different Channel by clicking on it, it will switch and will start to play music from that channel. I went on a trip of about 10 minutes duration, and it did seem to play several songs in a row from one channel. So, it is not clear to me what it is that prompts the system to switch from one channel to another, or why it will refuse to play a particular song even though it looks as if it's playing it. I filed bug reports but am curious if others have observed this behavior.
