atomic: fix load and store for armv7 and higher
Thomas Hutschenreuther: The original atomic implementation in pulseaudio based on libatomic stated that the intent was to use full memory barriers. According to [1], the load and store implementation based on gcc builtins matches sequential consistent (i.e.

meson: Add running-from-build-tree option
Arnaud Rebillout

meson: Add support for gcov
Arnaud Rebillout: Unlike autotools, we use the option --coverage, which is a synonym for-profile-arcs and -ftest-coverage (when compiling) and -lgcov (when linking).

meson: Add ORC support
Arnaud Rebillout

meson: Add udevrulesdir option
Arnaud Rebillout

meson: Add systemduserunitdir option
Arnaud Rebillout

test-daemon: No need to define dl-search-path
Arnaud Rebillout: There's already a hook that modifies the search path when run from the build tree. if (pa_run_from_build_tree()) { pa_log_notice("Detected that we are run from the build tree, fixing search path."); #ifdef MESON_BUILD c->dl_search_path = pa_xstrdup(PA_BUILDDIR PA_PATH_SEP "src" PA_PATH_SEP "modules"); #else c->dl_search_path = pa_xstrdup(PA_BUILDDIR); #endif } else I'm not sure how it works behind the hood, but by setting--dl-search-path, we get errors in the logs when running `make check-daemon`: E: [pulseaudio][daemon/ltdl-bind-now.c:75 bind_now_open()] Failed to open module /home/arno/proj/pulse/src/pa.up/src/.libs/.libs/module-native-protocol-unix.so: /home/arno/proj/pulse/src/pa.up/src/.libs/.libs/module-native-protocol-unix.so: cannot open shared object file: No such file or directory I: [pulseaudio][pulsecore/module.c:197 pa_module_load()] Loaded "module-native-protocol-unix" (index: #3; argument: ""). So basically, PA tries two paths, fails the first time (obviously we can see the path is not correct), then tries again with another path (where does it gets it?) and succeeds.

i18n: Don't compile with -ffast-math
Felipe Sateler: This flag results in calls to (at least) isfinite() and isnan() becoming skipped, and a constant false returned.

PulseAudio Release Tags

build-sys: Bump libpulse soversion
Arun Raghavan: We've added new API and updated an enum.

PROTOCOL: Bump to version 33
Arun Raghavan: Required for the addition of new pa_encoding_t values.

Update NEWS for 8.0
Arun Raghavan: ### PulseAudio 8.0 Changes at a glance: - Automatic routing more likely to change profile - OS X and NetBSD support improvements - Systemd journal logging for clients - New LFE balance programming interface - Module-dbus-protocol improvements - More flexible configuration file handling - pulsecore-8.0.so moved to a private directory - New script for measuring memory consumption - Various bug fixes and small improvements Detailed change log:

Update NEWS for 7.0 release
Arun Raghavan: ### PulseAudio 7.0 Changes at a glance: - LFE channel synthesis with low-pass filtering - New libsoxr based resamplers - Socket activation support for TCP - The "srbchannel" IPC mechanism enabled by default - More flexible jack detection support when using UCM - Exiting due to SIGTERM isn't considered a failure - Better support for Creative SoundBlaster Omni Surround 5.1 Detailed change log:

build-sys: add sb-omni-surround-5.1.conf to Makefile.am
Tanu Kaskinen: This is needed to get the file included in the release tarballs.

Revert "launch: Disable autospawn by default when systemd daemon support is enabled."
David Henningsson: This reverts commit 7276faca72e9696d4891daff139aee52509f43bf. 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.

suspend-on-idle: Fix monitor source handling
Tanu Kaskinen: Fixes a crash that happened due to calling pa_source_check_suspend() when d->source was NULL. ### PulseAudio 5.0 Changes at a glance: - BlueZ 5 support (A2DP only) - Reimplementation of the tunnel modules - Native log target support for systemd-journal - Resampler refactoring - --monitor-stream option for parecord and parec - "latency_msec" argument for module-rtp-recv - "inhibit_auto_suspend" argument for module-rtp-send - "auto" argument for module-tunnel-sink and module-tunnel-source - Removed module-bluetooth-proximity - Jack detection for line out - Laptop internal surround speaker volume support - Improved float->s16 and s16->float sample conversion for ARM NEON - "Available" flag for card profiles - Removed module-dbus-protocol from the default configuration - Lots of other enhancements, bug fixes, and documenation and i18n updates Detailed change log:

build-sys: Bump soname
Arun Raghavan: We dropped pa_format_info_free2 as an exposed symbol, but this was never exposed via headers, so not counting this as ABI change.

Most Popular This Year

meson: Enable raop-sink module, add raop lib, add openssl dependency
Arnaud Rebillout

meson: Enable lirc module, add lirc dependency
Arnaud Rebillout: This is unlike the autotools where we check that a header exist, here we use pkgconfig because upstream ships a pkgconfig.

alsa: Suppress udev detection of sound card for some units on IEEE 1394 bus
Takashi Sakamoto: A bug was filed to bugzilla.kernel.org for a quirk of some models which ALSA BeBoB driver supports. Bug 199365 - repeating bus resets on Firewire bus with Focusrite Saffaire 26/io

meson: Enable dbus-protocol module
Arnaud Rebillout: This is similar to alsa and rtp modules.

meson: Enable bluetooth modules, add bluez_util lib, add bluez and sbc dependencies
Arnaud Rebillout: Please notice that the bluez5 version seems wrong in the dependency declaration: `>= 4.x`, while we're talking about version 5. The ofono part will need to be made optional when we start to work on the meson_options file. I follow the current configure.ac to define 'HAVE_BLUEZ', but it looks like this part would benefit from a bit of rework.

meson: Add optional SoX Resampler support
