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.

It provides a virtual surround sound effect.
v2: Normalize hrir to avoid clipping, some cleanups
v3: use fabs, not abs
v4: implement changes proposed by Tanu Kaskinen
v5: likewise
v6: use channel map from hrir file
v7: remove hrir_ss and hrir_map form userdata
v8: update naming of sink
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/
The tunnel source has been broken since protocol v22 (PA 1.0),
and connecting fails with a protocol error. Fix.

If alsa settings/options were used, the string to construct the
name was freed, leading to dangling pointers to strings inside
the hashmap.

The practical problem is that some users were left with only one
"LFE on Mono" port, as analog-output was considered a subset of
analog-output-lfe-on-mono. Which was not what they wanted.

Flush the message queue before tearing down, and dest==NULL is valid in case moving failed.
With this my module-loopback finally no longer causes frequent crashes.
* If we don't have "Digital Speakers", we should say "Speakers"
instead of "Analog Speakers", and similar for other ports.
* Change "IEC958" to "S/PDIF" (more well known name)
* Add new ports and mappings for HDMI
* Change "Internal" to "Built-in" for the card name

"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 original intention of this code was probably that if
adding filter1 succeeded but adding filter2 failed, then
filter1 should be removed so that either both or none of the
filters get added.
We didn't do anything anyway in case of failures. When we
give NULL as the error, dbus_bus_remove_match() can act
asynchronously, so it becomes faster. Also, the bus daemon
can avoid sending any replies, which reduces the amount of
traffic.
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.

makes the Adrian echo canceller implementation optional at compile time
this patch supersedes an earlier patch proposal and addresses the following

* separate patch from speex dependency rework (Arun)
* check that at least one EC implementation is available (Arun)
* properly align yes/no in configure summary for Adrian (Frederic)
make speex library dependency optional, this affects the resampler
and the echo canceller module
this patch supersedes an earlier patch proposal and addresses the following
comments:
* fix order of pa_echo_canceller_method_t enum and ec_table (Frederic)
* the default resampler is speex if available as before, otherwise ffmpeg (Arun)
* does not touch the Adrian EC implementation (see separate patch) (Arun)
* If mapping_probe_paths() fails to open the mixer, all paths are now
removed from the mapping's path sets.
* pa_path_set.probed isn't really used for anything (removed).
* If profile probing is configured to be skipped, mapping_paths_probe()
should still be called.
Thanks to Tanu for spotting.

To be able to add ports to all profiles, we need to probe all
profiles at startup. To speed this up, we now have a cache of
probes paths which is owned by the profile set. Since paths
are now owned by the profile set, the path set must now have
a hashmap of paths instead of a linked list.

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 recommended way of setting available status is to call
pa_device_port_set_available, which will send a subscription event
to the relevant card. It will also fire a hook.
