Description of problem:
I have no idea of how this sound system can be reliably configured.  There are multiple places to find the setup.  VLC, for example has its own control of output.  It was working, but when I tried to play something from Youtube, the speakers were connected.  Bluetooth quit after I tried changing which output it became. Because the Pulse Audio Volume Control, Sound Preferences and Bluetooth all seem to have been developed in isolation, and nobody seems to be able to provide a guide to how they all interconnect, users must blunder around in the dark inorder to get things working.  I am grateful for the efforts of those who have made the system work again (It has been many months for my system) but we need some better documentation.  I don't mind spending some time figuring it out, but it would be much faster if someone could provide a block diagram of these modules, so that we had a map.
