[pulseaudio-discuss] [PATCH 0/8] Save/restore profile per port

This is essentially the patch set to avoid the case where
 * Speakers on 2.1 surround
 * plug in headphones, profile switches to stereo
 * unplug headphones, profile remains on stereo and now your
   subwoofer output disappeared (bad user experience), unless
   you select the profile manually again.

All the first sevent patches really lead up to the last one; which
makes module-switch-on-port-available a little refactored, a
little more straight forward, a little more aggressive in terms
of when it allows itself to change port and profile.

I hope it does not collide with other pending routing patch sets
too much; and as always when modifying the routing algorithm,
there is a ton of use cases you have a possibility to regress,
and I haven't tested them all.
Therefore testing would be much appreciated.

David Henningsson (8):
  card: Use pa_xmalloc0 when creating new cards and profiles
  card: Add variables for splitting up a profile
  alsa-mixer: Fill in input and output names
  device-port: Add preferred_profile field to pa_device_port
  card-restore: Save and restore "preferred profile" of port
  module-switch-on-port-available: Use input and output names
  module-alsa-card: Report available ports before unavailable ones
  module-switch-on-port-available: Route to preferred profile
