4 Subject: [PATCH 5/5] alsa: set availability for (some) unavailable profiles
6 The alsa card hasn't so far set any availability for profiles. That
7 caused an issue with some HDMI hardware: the sound card has two HDMI
8 outputs, but only the second of them is actually usable. The
9 unavailable port is marked as unavailable and the available port is
10 marked as available, but this information isn't propagated to the
11 profile availability. Without profile availability information, the
12 initial profile policy picks the unavailable one, since it has a
13 higher priority value.
15 This patch adds simple logic for marking some profiles unavailable:
16 if the profile only contains unavailable ports, the profile is
17 unavailable too. This can be improved in the future so that if a
18 profile contains sinks or sources that only contain unavailable ports,
19 the profile should be marked as unavailable. Implementing that
20 requires adding more information about the sinks and sources to
21 pa_card_profile, however.
