For volume control UIs to be able to show ports in inactive profiles,
expose all ports together with the card info. This includes updating
the protocol and the client API to show the connection between ports
and for which profiles the ports are relevant.
Update protocol to 26.

This module tries to switch to a port when availability changes to
"YES", and tries to switch away when availability changes to "NO".
Once there is a priority list infrastructure in place and ready,
this functionality might be redundant, but this will do as an
interim solution.
For Nvidia and Intel, support probing of up to four HDMI devices.
Also add port information to all HDMI profiles.

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
Our flist implementation suffers from the ABA problem
(see http://en.wikipedia.org/wiki/ABA_problem), causing PulseAudio
to crash very rarely, usually inside memblock operations.
By turning stored pointers into stored table indices, we have some
extra bits that we can use to store tag bits, which is a known
workaround for the ABA problem.

This allows clients to get a "fake" sample space for compressed formats
that we can support. This should make size/time conversion for things
like calculating buffer attributes simpler.
Since a given property can be single-valued, an array or (in the case of
ints) a range, clients need an API to figure out what type of value a
property holds. This adds such an API. The actual property type
enumeration is kept in the PA_PROP_* namespace and not the
PA_FORMAT_INFO* namespace so that it can later be reused for properties
generically if required.
This adds integer range/array and string array property getters to the
pa_format_info API. Corresponding tests added as well to ensure the code
is valgrind-clean.
The corresponding functions are added to map-file manually for now.
These utility functions could be handy to clients.
pa_format_info_to_sample_spec_fake() isn't made public, but the return
value is changed to keep in sync with pa_format_info_to_sample_spec().
This makes handling errors in getter functions more graceful, rather
than triggering warnings/asserts. Better to be less trigger-happy about
these things since this is now public-facing API.
We currently only have setters and clients need to be able to query
these values as well. The return types for these functions needed to be
changed to int since this is public API now.
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.

libtools causing relinking on installation, to make this succeed
libpulsecommon needs to be installed before the other libraries and the
padsp libraries needs to be installed afterwards.
Unfortunately autotools doesn't consider dependencies when running the
install target, thus we have to enforce the ordering ourselves
libpulsecommon is a private library only for use within pulseaudio, so
lets move it into a private directory
[ed: from discussion on IRC, while it looks redundant to have modules in
lib/pulse-$VER and private libraries in $pkglibdir, this is actually
desirable. For example, a multi-architecture libpulse would have a
$pkgdir per architecture (/usr/lib/<arch>/pulseaudio) whereas you'd
still want the server-specific modules in /usr/lib/pulse...) -- Arun]

assuming RAND_MAX is around 1<<31, rand() >> 1 generates large numbers as
random volume data; these likely causes saturated sample values after
applying the volume function -- not a good test
For muted channels, we forgot to increment a pointer, so if one
channel was muted but not the other, sound became distorted in a
Darth Vader like way. To test the difference, start two input
streams and pan one of them hard left (or right).
And hey, if you didn't think it sounded like Darth Vader, it's
your imagination that's broken, not mine! ;-)

If a *_UNLINK_POST hook causes a sink-input/source-output's sink/source
to go away, the subsequent attempt to update the sink/source status will
cause an assert. We deal with this by checking the sink/source status
before trying to update it.
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.
