+Subject: [PATCH] alsa: set availability for (some) unavailable profiles
+
+The alsa card hasn't so far set any availability for profiles. That
+caused an issue with some HDMI hardware: the sound card has two HDMI
+outputs, but only the second of them is actually usable. The
+unavailable port is marked as unavailable and the available port is
+marked as available, but this information isn't propagated to the
+profile availability. Without profile availability information, the
+initial profile policy picks the unavailable one, since it has a
+higher priority value.
+
+This patch adds simple logic for marking some profiles unavailable:
+if the profile only contains unavailable ports, the profile is
+unavailable too. This can be improved in the future so that if a
+profile contains sinks or sources that only contain unavailable ports,
+the profile should be marked as unavailable. Implementing that
+requires adding more information about the sinks and sources to
+pa_card_profile, however.
