Where did you set the "default"? Different tools have different 
meanings. e.g. the unsupported and not recommended padevchooser is 
definitely the worst offender here. It sets the default but you 
typically have to restart the application (or at least have the 
application reconnect to pulse) to have the options take effect. I 
cannot recommend against padevchooser enough. If you meant the official 
gnome tools then that is fair enough.

The -discover modules is not meant to be loaded automatically. You have 
to pick the option in paprefs if you want this on. The -discover module, 
once loaded, will load the -sink module for you if appropriate.

See above about the "dialogs" in question - padevchooser should not be 
used. pavucontrol doesn't use the term "default" any more as it is in 
appropriate in this context - it's just a fallback when a given stream 
has never been played before, or the device on which it was last played 
is unavailable.

If you can clarify what apps you were using, we can maybe offer some 
more advice on using them appropriately.

Note also that the RAOP support still has several flaws. I'm slowly 
getting myself enough headroom to dive in again and improve the support, 
so maybe by .21 it might be better :)
