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.

pa_channel_position_mask_t is type defined to uint64_t, and to display
uint64_t, it's better to use PRIx64 primitives.

For switching profiles, we are a little more cautious, only switch
from an unavailable port to an available one. Profile switching is
mainly used for HDMI/DisplayPort, and this is to avoid switching from
analog to HDMI/DP when it becomes available.

and replies for more information.

Calling adjust_rates after teardown results in segfault, and
judging from the Ubuntu bug report, this can happen.
Actively prevent this by destroying the time event, and by
setting adjust_time to 0, we also prevent this routine being
called on max request update.

ConsoleKit has been deprecated and replaced by systemd's logind daemon,
hence provide the same functionality of module-console-kit in
module-systemd-login. This also makes sure that the CK module becomes a
NOP if the system is booted with systemd, resp. that the systemd module
becomes a NOP if the system is booted without systemd, thus being nice
to OSes such as Debian which want to support multiple init systems.
A part of Xen's paravirtualized audio driver has been developed as a
pulseaudio module. This module acts as a tunnel over Xen's shared memory
mechanism and allows a domU guest to send audio data to a dom0 backend.

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.

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
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.

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

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.
