As far as I can see, having a mono path in a stereo mapping doesn't
make any sense. It also causes breakage: if the Master Mono mixer
element has two volume channels, the analog-output path gets removed
due to being a subset of analog-output-mono, and that in turn causes
the Master element getting muted. Users generally don't like that.

When a "Headphone Mic" jack becomes available, we do not know if
a headphone or a mic has been plugged in. Therefore, setting both
paths to "unknown" is, in theory, the correct thing to do.
However, in practice, people are more likely to plug in a headphone
rather than a mic. Therefore, allow autoswitch to the headphone port
when the jack is plugged in.
A more advanced implementation would consider what was plugged in last
time depending on what port was selected on the input side at that
time, and set availability accordingly. However, such an implementation
will have to wait (probably at least until we have our fancy routing
system implementation).

The mixer paths are not available in ${builddir} - we need to look in
${srcdir}. This should fix running an in-tree build without make install
as well as alsa-mixer-path-test in make distcheck.
Since the most straightforward way to define PA_SRCDIR was in
Makefile.am, I'm moving PA_BUILDDIR there as well for consistency.
On some machines which has a headset jack, the headset mic does not have its own
jack detection. Then we can look at the headphone jack to get some indication:
We know that if the headphone is unplugged, so is the headset mic. The opposite
is not guaranteed since the user might have plugged in a headphone, not a headset.
Also, there exist multi-function jacks which support both Headphone, Mic in headphone jack
and Headset Mic. In this case the jack name will be "Headphone Mic", not "Headphone", so
we need to include this name too.

Due to a misconfiguration on my side my hdmi card didn't load with
snd-hda-codec-hdmi but through the fallback mechanism. Pulseaudio
would crash during early because hctl_handle was null, so skip
init_eld_ctls when hctl_handle is null to prevent a crash.

Previously, a drain request was acknowledged up to two hw buffers
too late, causing unnecessary delays.
This implements a new chain of events called process_underrun
which triggers exactly when the sink input has finished playing,
so the drain can be acknowledged quicker.
It could later be improved to give better underrun reporting to
clients too.

Generalize the availability flag in order to be used beyond the scope of
ports.
However, pa_port_availability_t is left unchanged to avoid modifying the
protocol and the client API. This should be replaced by pa_available_t
after a validation phase of this new generic enum type.
The previous patch removed module-gconf's dependency on the userdata
pointer of the free callback, and that was the only place where the
userdata pointer of pa_free2_cb_t was used, so now there's no need for
pa_free2_cb_t in pa_hashmap_free(). Using pa_free_cb_t instead allows
removing a significant amount of repetitive code.
If 'PlaybackChannels' and 'CaptureChannels' are absent in the UCM
file for a device, assume the device is stereo duplex.

I was looking at a log that showed that a suspend happened (at

This patch tries to make sure that that won't happen again.
A left over "required-any" made this path useless for most people.
While we're at it, also add "Front Headphone" like for the normal

We inadvertantly stopped supporting non-standard rates when the
passthrough work was done. This makes sure that if no standard rates are
supported, we try to fallback to whatever ALSA gives us.
When a rewind is requested on a sink input, the request parameters are
stored in the pa_sink_input struct. The parameters are reset during
rewind processing, and if the sink decides to ignore the rewind
request due to being suspended, stale parameters are left in
pa_sink_input. It's particularly problematic if the rewrite_bytes
parameter is left at -1, because that will prevent all future rewind
processing on that sink input. So, in order to avoid stale parameters,
every rewind request needs to be processed, even if the sink is
suspended.

The IDT/Sigmatel codec driver often creates a "Mic Jack Mode" for
every mic jack, so it can change functionality between Mic and Line In.
However, as the "Mic Jack" is the standard naming, our current solution
does not make the Line In port unavailable when nothing is plugged in.
This patch makes the "Line In" port not to be created just because there
is a "Mic Jack Mode" that could be set to "Line". This makes the behaviour
consistent with e g "Dock Mic Jack Mode", "Front Mic Jack Mode" etc, where
we don't create a "Dock Line" or "Dock Mic" port either.

In UCM basic functions, we only assign intended roles from modifier
to sink/source, but we don't have a chance to set the ucm modifiers.
Here we amend the functions so that when roled stream starts or
stops, we have the following results:
1. stream will be routed to sink/source specified in modifier by
module-intended-roles
2. After that, modifier will be enabled or disabled.
3. when multiple streams with matched roles of modifier start, only
the first one will enable the modifier, and when they end, the
last one will disable the modifier.

Modifiers may have their own PlaybackPCM/CapturePCM and for these, we
create separate sinks/sources. These are marked with the
device.intended_roles property to let role-based routing take care if
streams are tagged appropriately.
The proplist isn't used by the conventional alsa-mixer code path, but
can be used by UCM to transfer properties from UCM data to the
sinks/sources corresponding to a mapping. These properties could be used
later in policy, etc.
The specific use for which I'm writing this now is for UCM modifiers
that have their own PlaybackPCM/CapturePCM field. These will be
translated to a separate sink/source corresponding to the modifier by
adding an additional mapping per sink/source. These mappings' proplist
will be populated with the name of the modifier and corresponding
"device.intended_role" property. The latter will be used in the usual
routing-by-role way, and the former will be used during sink/source
activation and deactivation to know what UCM modifier is to be enabled
or disabled.
Jack in UCM is decided by UCM device name, although in fact
not all UCM devices have "jacks". Because port is also mapped
to UCM device, we can always find target port when some jack
event happens.

UCM basic functions will provide another way to handle the alsa mixer
and controls. That means alsa card module will make use of alsa ucm
configurations provided by various audio systems instead of mixer and
paths configurations provided by PA. PA profiles come from UCM verb, PA
sinks/sources and ports come from UCM devices.
In case the proper UCM configurations are found, ucm branches are
activated, or we will still fall through to the original way.
