The current LFE crossover filter removes low frequencies from the main
channels and puts them into the LFE channel with the wrong amplitude.
It is not known for sure what is the correct relative amplitude (acoustic
measurements are required with real hardware), and changing that might
introduce a new bug, "it clips the LFE channel".
So just disable the feature by default until a better understanding
emerges how it should work. This, essentially, returns the defaults
to their state as of PulseAudio 6.0.
Some more observations:
- Most of available active analog speakers on the market do the
necessary crossover filtering already, and HDMI receivers can be
configured to do that, too, so a crossover filter in PulseAudio is
harmful in these use cases.
- The "laptop with a builtin subwoofer" use case requires manual
configuration anyway because the default crossover frequency (120 Hz) is
wrong for laptop speakers.
- Finally, Windows 10 with a built-in USB audio driver does not synthesize
the LFE channel given a 5.1 card and a stereo audio stream by default.

Now that all layers in the stack support memfd blocks, add memfd
support for the daemon's global core mempool. Also introduce
"enable-memfd=" daemon argument and configuration option.
For now, memfd support is an opt-in feature to be activated only
when daemon's enable-memfd= is set to yes.

Now that all layers in the stack support memfd blocks, add memfd
pools support for client context and audio playback data.
Use such memfd pools by default only if the server signals memfd
support in its connection negotiations.
Also add ability for clients to force-disable memfd transport
through the `enable-memfd=' client configuration option.

I want to enable client.conf.d, because in OpenEmbedded-core we have
a graphical environment called Sato that runs as root. Sato needs to
set allow-autospawn-for-root=true in client.conf, but the default
configuration in OpenEmbedded-core should not set that option. With
this patch, I can create a Sato-specific package that simply installs
50-sato.conf in /etc/pulse/client.conf.d without conflicting with the
main client.conf coming from a different package.
daemon.conf.d is enabled just because it would be strange to not
support it while client.conf.d is supported.
When crossover_freq is set to 0, this restores the old behaviour
of letting the LFE channel be the average of the source channels,
without additional processing. This can be useful e g in case the
user already has a hardware crossover.

Add a user defined parameter lfe-crossover-freq for the lfe-filter,
to pass this parameter to the lfe-filter, we need to change the
pa_resampler_new() API as well.

pacat and paplay man pages both claim to describe the paplay program
(which is actually a symlink to pacat) -- this is inconsistent and
redundant, so drop the paplay man page
a follow-up patch will add man page symlink for all programs
implemented by pacat, not just paplay

Using the new systemd socket activation for PulseAudio will cause PulseAudio to not
have any connection with D-Bus, breaking device reservation protocol, module-jackdbus-detect
and module-dbus-protocol. Therefore, autospawn is now still enabled by default even if you
build with systemd daemon headers.

When enabled, this method is prefered over pulseaudio's built in
systems so we should try our best to ensure that it cannot be spawned
outside of the mechanisms desired.
Packagers should call 'systemctl --global enable pulseaudio.socket' to
enable the socket for all users, or alternatively ship an enabling
symlink in /usr/lib/systemd/user/sockets.target.wants/ folder. It may
also make sense for distributions to add in a ConditionNNN= line to the
socket unit if they have a downstream mechanism for enabling or
disabling pulseaudio.
If individual users wish to opt out of this vendor (or administrator)
decision, they can call 'systemctl --user mask pulseaudio.socket'
The journal is a component of systemd, that captures Syslog messages,
Kernel log messages, initial RAM disk and early boot messages as well
as messages written to STDOUT/STDERR of all services, indexes them and
makes this available to the user.
It can be used in parallel, or in place of a traditional syslog daemon,
such as rsyslog or syslog-ng.
The journal offers a couple of improvements over traditional logging
facilities (e.g. advanced filtering capabilities).
This patch adds support for logging directly to the journal using its
native API.

This consumes less power, has low (no?) perceivable difference, and
allows the default configuration to work out of the box on low-end
systems (such as netbooks).
This adds two new commands to pactl:
set-default-sink
set-default-source
This command has been part of the native protocol for a long time,
no reason not to expose it in pactl.
This patch adds the ability to toggle mute for sink/sources and
sink-inputs and source outputs.
All mute commands now accept 1|0|toggle as an argument.
