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 thinkpad ACPI driver sometimes creates a virtual sound card,
which at best exposes a volume control. Save some startup time, and
unnecessary error messages in the log, by ignoring it.

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.

The priorities should be set in the approximately likeliness that someone
would like to use them. This is hard to guess of course, but this is
a better guess compared to the existing configuration.

The "Line HP Swap" element needs to be set correctly for some Dove
boards to work correctly. Thanks to Daniel T Chen for the patch.

This switch needs to be off for analog output to work on several
Audigy cards.

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.

Some laptops have 'Internal Mic 1' exposed as an 'Input Source', e.g., Dell
XPSM 1530, so handle these, too.

This is not 100% ideal as we have not way to tie specific boosts to specific
inputs and this particular chipset (as noted in #772) appears to
support just that.
For the time being incorporate it into the normal boost logic.
