[pulseaudio-discuss] [PATCH v2 0/5] No more dual-direction ports.

[Tanu Kaskinen]

In my mind a port is an "atomic routing unit", and a port
that can be used for both input and output is not atomic (it
defines two routes). An example of practical problems having
two routes in one port: you can't set a property for output
without setting it also for input.

The first version of this patch set was sent in April:
http://thread.gmane.org/gmane.comp.audio.pulseaudio.general/13010

Changes in v2:
 - Dropped the "device-port: Initialize profiles in
   pa_device_port_new()" patch, because a fully equivalent
   patch has already been merged.
 - As suggested by David, I added a new path option to be
   used in path description lookup: "description-key".
 - The logic for making path descriptions unique is now
   retained (it was completely removed in v1).
 - General rebasing work on top of the newest master.

Tanu Kaskinen (5):
  card: Store a pa_card pointer in pa_card_profile.
  switch-on-port-available: Prepare for port->is_{out,in}put going
    away.
  alsa-mixer: Introduce "description-key" option for paths.
  alsa-mixer: Remove the "name" option from the "General" section of
    path configuration files.
  device-port: Make it impossible to have a dual-direction port.
