Recent Activity

rtp-send: add configurable RTP stream name
Ing. Jaroslav Safka: Add configuration option 'stream_name' for stream/session name so user will see it on receiver side as RTP Strean ($stream_name)

alsa-mixer: make the mono mapping a fallback only
Tanu Kaskinen: If a sound card doesn't have the "front" device defined for it, we have to use the "hw" device for stereo.

proplist: add and use const version of MAKE_HASHMAP macro
Lyndon Brown

format: Add support for Dolby TrueHD and DTS-HD HBR passthrough
Pierre-Louis Bossart

bluetooth: Remove BlueZ 4 support
Luiz Augusto von Dentz: BlueZ 4 is no longer supported by BlueZ community for a long long time, also by moving to BlueZ 5 it should make it even more clearer that BlueZ 4 is no longer an option.

Activity Earlier In The Year

gsettings: run gsettings-data-convert from gsettings-helper
Tanu Kaskinen: This was originally planned to be done by paprefs when it starts, but since the schema is now fully controlled by pulseaudio, it makes sense to run the conversion from pulseaudio instead.

gsettings: add the modules schema to the schema description file
Tanu Kaskinen: Originally the idea was to provide the "modules" schema with paprefs, but since module-gsettings refers to the "modules" schema in its code, that would make module-gsettings depend on paprefs, which is not good.

module-gsettings: new module to store configuration using gsettings
Sylvain Baubeau: GConf is deprecated, and distributions are removing it.

replace sink/source SET_STATE handlers with callbacks
Tanu Kaskinen: There are no behaviour changes, the code from almost all the SET_STATE handlers is moved with minimal changes to the newly introduced set_state_in_io_thread() callback.

alsa-mixer: add another hardware ID for Traktor Audio 6
Tanu Kaskinen: This is based on a patch by Rolo that replaced the old ID with the new one.

ladspa-sink: add module argument to set sink input properties
Roliga: 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

client-conf: Add a default value for disable-memfd
Arun Raghavan: This got missed while adding the client option.

switch-on-connect: add option to ignore virtual sinks/sources
Georg Chini: 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.

sink-input, source-output: add sink/source_requested_by_application flag
Tanu Kaskinen: When a stream is created, and the stream creator specifies which device should be used, that can affect automatic routing policies.

sconv-s16be: declaration/implementation mismatches
Constantine Kharlamov: Fixes the following compiler errors:

PulseAudio Release Tags

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

NEWS: add GNU Hurd support
Tanu Kaskinen: For some reason this was left out when copying the feature list from the release notes.

padsp: Make it compile on musl
Khem Raj: break assumptions on glibc and there is no stat64 on non glibc C libraries

qpaeq: change license from AGPL to LGPL v2.1
Tanu Kaskinen: This removes one unnecessary exception in the PulseAudio licensing terms.

sink-input, source-output: add a couple of assertions
Tanu Kaskinen: Coverity complained about data->sink being possibly NULL when it's dereferenced later.

client-conf: Add a default value for disable-memfd
Arun Raghavan: This got missed while adding the client option.

volume: improve documentation
Tanu Kaskinen: Changes: - Mention that source outputs have volume too. - Don't claim that most distributions have flat volumes enabled. - Volumes use a cubic scale, not logarithmic.- Reword the warning about using the conversion functions on hardware volumes.

ladspa-sink: add module argument to set sink input properties
Roliga: 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
