separate mono LFE pin nothing seems to use it. To make matters worse
it does confuse PulseAudio's port selection slightly which causes
audio in virtualbox not to work out of the box."

Some ASUS netbooks, such as the 1015 CX, have only one 3.5 mm jack,
but it can be used either as a headphone or as a mic (but not both
simultaneously).
This patch adds support for the "Headphone Mic" path that is used
on these devices, so that we can use the jack as an external mic, and
doing so without muting the speaker.

Many desktops have headphone on the front and line outs on the back.
Sometimes this means that the headphone is labelled "Front Headphone Jack",
but the volume controls are only "Headphone Playback Volume", i e,
without the "Front" prefix.

Some devices have inverted right channel, so when you add left and right,
the result is silence, or very faint sound. In recent kernels (3.5,
perhaps also 3.4) these are starting to be marked with a special
"Inverted Internal Mic" capture switch.
While we might want to add some reverse summing mechanism in the
future, for now, we just turn the thing off to avoid the problem of
recording silence.

For kernel 3.6, "phantom jack" kctls have been added. They serve as
a marker that a particular port exist. They were made so we can detect
that there actually are speakers and internal mic on a laptop, even if
there are no other indications (volume controls etc).

Several laptops have speaker ports, and/or internal mic ports, but we have
no way of detecting that. So we make the port(s) always show up for these
devices.

Changes in v2:
- Call the mapping a generic 4-channel input mapping
instead of a 4-channel mic array mapping. The mapping
will be used also by sound cards that have two stereo
input jacks, so in those cases talking about mic arrays
is wrong.
- Added a comment about using the "hw" device name.

Some older cards do not have jack detection. This patch makes the
port still show up.
An implementation detail: the "required = ignore" line has in itself
no effect, but we have to write *something* there, or else the entire
jack detection section will be ignored by the parser.

While developing the new UI we had to ask ourselves the question of whether
"speakers" should be considered available when headphones are plugged in.
In most cases, they are not available and therefore we should list them
as such.
OTOH, we don't want unplugging the headphones to be considered an act of
wanting to use the speakers (the user might prefer HDMI), and there might
be line-outs that keeps the speakers from unmuting anyway. So, at this point,
I think the most reasonable would be to make the speakers have
PA_PORT_AVAILABLE_NO when headphones are plugged in and
PA_PORT_AVAILABLE_UNKNOWN when they are not. But we might want to revisit
this decision once we have the priority lists up and running.
The same reasoning applies for "Internal Mic", which should become unavailable
when any other mic is plugged in.

Support the new jack detection interface implemented in Linux 3.3
(and Ubuntu's 3.2 kernel).
Jacks are probed and detected using the snd_hctl_* commands, which
means we need to listen to them using fdlists. As this detection
needs to be active even if there is currently no sink for the jack,
so this polling is done on the card level.
Also add configuration support in paths, like this:
[Jack Headphone]
required-any = any
...where 'Jack Headphone' should match 'Headphone Jack' as given by
ALSA (as seen in e g 'amixer controls').
"Required", "required-any" and "required-absent" is supported. Using
required-any, one can have several ports even though there is no
other indication in the mixer that this path exists.

Hi. Could you please apply the attached trivial patch so that I could drop
the corresponding instructions from dcaenc's README file in the future? It
adds a profile for on-the-fly DTS encoding, similar to the existing AC3
profile.

Subject: [PATCH] alsa: add DTS profile
This requires dcaenc from http://aepatrakov.narod.ru/dcaenc/
"Front Speaker", "Surround Speaker" seems to be a common enough name
to make it into alsa-utils, so we should probably care about it as
well. In this case, there was a macbook pro whose speakers didn't work
without these controls.

The recent change to turn off the IEC958 element for analog paths
exposed a bug in AC3 profiles. These were inheriting the analog output
path instead of explicitly selecting the iec958 path.
Thanks to David Henningsson for pointing this out.
This is needed for the Creative Audigy CA0106 to work. Also makes sure
that the LED for optical out is shut down in analog modes on MacBooks
(these share a port for analog and digital output).

Just like we turn off the "Front Mic" element when we select "Rear Mic",
we should also turn off the "Front Mic Boost" element. And the same for
the other inputs.

The Kinect shows up as a UAC device after the firmware has been loaded,
but in order to be detected by pulseaudio a 4-channels input only
mapping is needed. Provide a new profile for that and set it with a udev
rule.

I've seen more than one system where the volume control named
"Front" is a part of audio path for headphones. This is somewhat
of a compromise: While we don't merge it into the path, as that
would be regressing machines where "Front" isn't a part of the
audio path, it would still enable sound on these machines.

Now that subset mixer paths are removed, this workaround is no longer needed.
This effectively reverts 1c38b5d478 but due
to me forgetting to add files and adding a couple extra workarounds after,
it's easier to just do this manually rather than run git-revert.
This is a workaround - these usb headsets have one output volume
control only, labeled "Speaker". This causes the default profile
set to not control the volume at all, which is a bug. Workaround
that by creating a separate profile set.

This change makes it possible to configure an arbitrary constant volume for a
volume element in the path configuration, which is applied when the path is
selected. Note: this is only useful when the exact hardware and driver are
known beforehand.
This feature is mainly useful in embedded systems that have built-in speakers.
In such situations the full audio path is known beforehand, so it's possible to
know what is the maximum sensible volume, and any higher volume can be
disabled.
The volume limit is set in path configuration files in the [Element] section,
using option "volume-limit". The value is the desired maximum volume step of
the volume element.
Make sure that mic and line (with common names) use the specific
path instead of the analog-input one.

Now you can add required-any to elements in a path and the path
will be valid as long as at least one of the elements are present.
Also you can have required, required-any and required-absent in
element options, causing a path to be unsupported if an option is
(not) present (simplified example: to skip line in path if
"Capture source" doesn't have a "Line In" option).

This is needed to better support out of tree builds (including
distcheck) and to ensure the necessary folders are created in the
build tree on configure and also works around an intl-tools bug
(https://bugs.launchpad.net/intltool/+bug/605826)
The Makefile.am's used are minimal (and in some cases completely
blank). At present they do not include anything interesting
with the majority of the real work still done by the monolitic
src/Makefile.am
It may make sense to start splitting out src/Makefile.am into
smaller chunks but this commit makes the minimum changes to address
the issues that result from using make distcheck and other out of
tree builds.
Note: This 'breaks' the ability to type make in e.g. the src/modules
folder and have all of PA rebuilt accordingly (this is because the
static Makefiles previously present just did a "make -C ..") which
was purportedly for use in emacs. But I'm sure there will be a better
and more robust way to configure emacs to do your builds properly if
this behaviour is still desirable.
