When a Bluetooth headset is connected only to HFP profile (not connected
to A2DP) and host streams to it, a crash occurs if host disconnects.
When HFP disconnects, audio thread will fail on POLLHUP then generate
a message to set PA profile to Off before ending.
If this message is managed before PA unload bluetooth device module,
all works fine.
But, if this message is managed during module unload, this finish by
re-entrance in release code (stop_thread) and a crash.
This fix prevents to process profile change when module is unloading.
pa_bool_t and dbus_bool_t cannot be used interchangably since their size
might (and do) vary. This caused a crash on some systems which was
reported and root caused by: Aidan Thornton <makosoft@googlemail.com>.

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.

Log in as user A, fast user switch to user B, let user B change
port, volume or mute status, then switch back to user A.
At this point we must make sure that the ALSA and PA volumes are
synchronised by writing to the ALSA mixer when the ALSA device
becomes available.

If deferred volumes were activated, set_volume does not really set
the volume, and is probably only meant to be called from the main
thread.
As we're currently really setting the port and the mute here (i e
modifying ALSA), we should really modify the volume as well.

Make sure we can't be called into by remaining references to
sink-inputs and source-outputs after we have unloaded, as
that will likely lead to segfaults.

Coverity thinks that device_name can be NULL when it's
dereferenced by strcmp. Adding an assertion doesn't hurt
here (in my opinion), and that should get rid of the
warning.

Valid channel id range is from 0 to SND_MIXER_SCHN_LAST,
inclusive, so the size of the masks array in pa_alsa_element
has to be SND_MIXER_SCHN_LAST + 1. Similar "too small"
arrays were also in alsa-sink's and alsa-source's userdata,
but actually those arrays were not used at all so they were
removed.
element_is_subset() in alsa-mixer.c skipped the last channel
id when iterating the element masks array; that's now fixed
as well.
Thanks to David Henningsson for spotting the too small
arrays in alsa-sink and alsa-source and the
element_is_subset() problem.
Changes since v1:
Use max value of jack_port_get_latency_range to calculate the latency
and squash compiler warnings cased by using jack_port_get_total_latency
Modifying latency only works inside a callback, and for hardware the
latency is generally fixed on jack, so just take the max value.

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

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.

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.
Signed-off-by: David Henningsson <david.henningsson@canonical.com>
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.

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.
