[pulseaudio-discuss] [PATCH v0 03/11] dbus: Support dynamically created card profiles

[Mikel Astiz]

From: Mikel Astiz <mikel.astiz at bmw-carit.de>

If a port availability update is received and the corresponding card
profile was not previously registered, it means the profile has been
created dynamically. Therefore, the D-Bus objects need to be updated.
