We use ChurchStreaming.tv with Church Online Platform and ChurchStreaming.tv offers an Audio Only version of their player. I've had requests from people who are driving cars to be able to get the audio without video to save on cellular data. So I have a player, but I'm not sure where to put it in Church Online Platform.
I can embed this in a page on our main website, but then users are switched to a different experience. Some users might want to do audio only because of bandwidth concerns, but still want access to live chat.
Ideally there would be a small button in Church Online Platform that the user could click on during an event to switch from the video player to the audio player.
