[pulseaudio-discuss] [PATCH v2 0/2] Improve default device policy

[Tanu Kaskinen]

The first patch refactors the default sink/source handling code to make
it easier to add new conditions to how the default sink and source are
chosen. It's not pure refactoring, though: the patch also fixes some
cases where change notifications were not sent, and the D-Bus protocol's
default sink/source functionality should work much better now, and there
are new log messages for default device changes.

The second patch fixes improves the default sink/source selection by
avoiding devices whose active port is unavailable.

Changes in v2:
 - Added a note about the D-Bus protocol bug to the first patch's commit
   message.
 - Changed the default sink/source selection logic to prefer the current
   default device when comparing two devices with the same priority.
 - Removed the redundant call to pa_core_update_default_sink/source()
   when unlinking the current configured default sink or source.
   pa_core_set_configured_default_sink/source() will call that function
   anyway.
 - Made the comment on pa_core.default_sink/source a bit more verbose.
 - Dropped the patch that uses the active port's priority as the
   sink/source priority. The discussion is ongoing about what to do
   about that, so I'll submit that patch separately later, or a
   different patch that achieves the same goal.

  refactor default sink/source handling
  core, device-port: check availability when choosing the default device
