We have so far assumed that HDMI always uses device indexes 3, 7, 8, 9,
10, 11, 12 and 13. These values are hardcoded in the path configuration.
The Intel HDMI LPE driver, however, uses different device numbering
scheme. Since the indexes aren't always the same, we need to query the
hw device index from ALSA.
Later patches will use the queried index for HDMI jack detection and ELD
information reading.

When module-filter-apply tries to find a matching source-output for
a given sink-input and a stream within the same group exists on the
monitor source of the filter, module-filter apply falsely assumes
that the source belongs to another instance of the filter and tries
to access source->output_from_master->source, which leads to a
segmentation fault.
This patch fixes the issue by ignoring the stream if the source is
the monitor source of the filter.
glibc 2.27 is to be released soon, and it will provide memfd_create().
If glibc provides the function, we must not define it ourselves,
otherwise building fails due to conflict between the two implementations
of the same function.

Usually PulseAudio is built with a linker that supports the -z,now
option, and that option should have the same effect (i.e. the dynamic
linker resolves all symbols when the program is started) as re-execing
with the LD_BIND_NOW environment variable set, so usually the re-execing
is redundant.
BugLink: https://bugs.freedesktop.org/show_bug.cgi?id=104789
It was reported that PulseAudio causes error messages in syslog from
dbus-daemon:
Jan 14 04:51:32 gentoo dbus-daemon[2492]: [system] Rejected send message, 2 matched rules; type="error", sender=":1.15" (uid=1000 pid=2864 comm="/usr/bin/pulseaudio --start --log-target=syslog ") interface="(unset)" member="(unset)" error name="org.bluez.MediaEndpoint1.Error.NotImplemented" requested_reply="0" destination=":1.1" (uid=0 pid=2670 comm="/usr/libexec/bluetooth/bluetoothd ")
The default policy on the system bus is to not let any method call
replies through if they have not been requested, and apparently
bluetoothd doesn't want replies to the Release() call.
This also changes the reply type from error to normal reply. The "not
implemented" error didn't make sense to me. We don't do any cleanup in
the Release() handler, probably because there's nothing to do. If there
is some cleanup that we should do, then it's a serious bug not to do it.

Allow usage of an already existing fifo (named pipe) within the
pipe-sink module. Also, the used fifo is going to be removed upon
module unload only if the fifo is created by the same module.
This is based on a patch by Rolo <rolo@wildfish.com> that replaced the
old ID with the new one. I deemed it better to leave the old ID in use
(I can't verify if the old ID was correct or not).
The original commit message:
Every time I reinstall or update Ubuntu I have to make this change
to get it to recognise my Native Instruments Traktor Audio 6
external soundcard.
Each time I remember the change by hunting down this forum post in
German,
https://forum.ubuntuusers.de/topic/traktor-audio-6-erkannt-aber-nicht-anwaehlbar/3/#post-8759808
(I don't speak German).
I'm not sure if the ID is just incorrect or if perhaps the hardware
identifies itself differently on slightly different models, so
perhaps we need to duplicate the line - I'm well outside of my
comfort zone here and I know barely anything about how hardware
works on Linux but figured if it helps me it would help others so I
should put it forward.
Thanks!
Previously the suspend cause was logged as a hexadecimal number, now
it's logged as a human-friendly string.
Also, the command line interface handled only a subset of causes when
printing them, now all suspend causes are printed.
The Intel HDMI LPE driver works in a peculiar way when the HDMI cable is
not plugged in: any written audio is immediately discarded and underrun
is reported. That resulted in an infinite loop, because PulseAudio tried
to keep the buffer filled, which was futile since the written audio was
immediately consumed/discarded.
This patch adds special handling for the LPE driver: if the active port
of the sink is unavailable, the sink suspends itself. A new suspend
cause is added: PA_SUSPEND_UNAVAILABLE.

This removes the symdef header generation m4 magic in favour of a
simpler macro method, allowing us to skip one unnecessary build step
while moving to meson, and removing an 11 year old todo!
The function is declared in pulse/format.h and it has Doxygen
documentation, which tells me that the intention was to make the
function available to clients.

In proces(), the do_move() function calls pa_{sink_input,source_output}_set_property().
This triggers a call to {sink_input,source_output}_proplist_cb() which called process()
a second time.
This patch avoids the duplicate and nested call to process() by checking if
PA_PROP_FILTER_APPLY_MOVING is set in {sink_input,source_output}_proplist_cb().
This patch adds a sink_input_properties argument to module-ladspa-sink,
which can be helpful for customizing the appearance of the sink input in
various volume control applications, or to differentiate between
multiple instances of the module.
The get_cpuid() function in cpu-x86.c was buggy on x86-64. When building
without optimizations, the homegrown assembly code overwrote the
beginning of the function argument list on the stack. That happened to
work fine on regular x86-64, but caused crashing with the x32 ABI.
At least GCC and clang provide cpuid.h, which has the __get_cpuid()
function that can be used instead of the homegrown assembly.
The PA_REG_* constants can be removed as well, because they're not used
any more.

When a sink input was unlinked between the calls to pa_sink_move_all_start() and
pa_sink_move_all_finish(), pa_sink_move_all_finish() tried to finish the move
of the already unlinked sink input, which lead to an assertion in
pa_sink_input_finish_move(). The same applies for the source side.
This patch fixes the problem by checking the state of the sink input or
source output in pa_*_move_all_finish().

module-switch-on-connect would switch to any new sink, even if the sink
was a filter or a null-sink.
This patch adds a command line option ignore_virtual to the module, which
lets module-switch-on-connect ignore virtual sinks and sources. The flag
is true by default because the purpose of the module is to switch to new
hardware when it becomes available.
module-device-manager doesn't change the routing of those streams that
have been explicitly routed by the user, which is good. Similarly, it
should leave those streams alone whose routing was decided by the
application that created the stream. This patch implements that.
BugLink: https://github.com/wwmm/pulseeffects/issues/99
When a stream is created, and the stream creator specifies which device
should be used, that can affect automatic routing policies.
Specifically, module-device-manager shouldn't apply its priority list
routing when a stream has been routed by the application that created
the stream.
A stream that was initially routed by the application may be moved for
some valid reason (e.g. user requesting a move, or the original device
disappearing). When the stream is moved away from its initial device,
the "device requested by application" flag isn't relevant any more, so
it's set to false and never reset to true again.
The change in module-device-manager's routing logic will be done in the
following patch.

The filter sources should have the same max_rewind as the master source,
but these modules didn't update max_rewind when the master max_rewind
changed.
Previously max_rewind was always set to the full hw buffer size, but
the actual maximum rewind amount is limited to the part of the hw buffer
that is in use.
The rewind request that was done when lowering the sink latency had to
be moved to happen before updating max_rewind.
The practical benefit of this change: When using a filter source on a
monitor source, the filter source latency is increased by max_rewind.
Without this change the max_rewind of an alsa sink is often
unnecessarily high, which leads to unnecessarily high latency with
filter sources.
Monitor sources themselves don't suffer from the latency issue, because
they use the current sink latency instead of max_rewind for the extra
buffer that they keep to deal with rewinds.
Coverity complained about data->sink being possibly NULL when it's
dereferenced later. It was difficult for me to figure out whether that
was a false positive or not. Hopefully the comments make it a bit
easier to reason about the code in the future.

This rejigs the update_rate() logic to encompass changes to the sample
spec as a whole, as well as passthrough status. As a result,
sinks/sources provide a reconfigure() method which allows
reconfiguration as required.
The behaviour itself is currently unchanged -- alsa-sink/-source do not
actually implement anything other than rate updates for now (nor are
they ever requested to). This can be modified in the future, to allow,
for example 24-bit output when incoming media supports it, as well as
channel count changes for passthrough sinks.
Another related change is that passthrough status is now part of
sink/source reconfiguration, and we can stop doing a suspend/unsuspend
when entering/leaving passthrough state. So that part is now divided
in two -- pa_sink_reconfigure() sets the sink in passthrough mode if
required, and pa_sink_enter_passthrough() sets up everything else
(this currently means only volumes, but could disable other processing)
for passthrough mode.
