Other Activity This Week

bluetooth: add modarg to allow disabling mSBC codec
Igor V. Kovalenko: Add module-bluetooth-discover argument enable_msbc, default is true (enabled)

bluetooth: set initial packet size to 60
Igor V. Kovalenko: Raise initial MTU size to fix frame size when hci can do 60 byte frames.

bluetooth: add wideband audio codec negotiation to HFP
James Bottomley: The HFP protocol supports the ability to negotiate codecs if that is supported by both AG and HF.

bluetooth: add support for mSBC codec
James Bottomley: Adding processing support for the mSBC codec is somewhat problematic, because, although it is a SBC codec, the a2dp handling can't simply be reused because the codec is used on an eSCO link with transparent data, meaning the transmission unit has to be 48 bytes (fragmenting the codec packets) and reassembly and boundary detection is required to be done by the implementation.

bluetooth: add CVSD codec implementation
Igor V. Kovalenko: Part-of: <

sink-input, source-output: Add hooks for preferred device changes
Tanu Kaskinen: The hooks are fired when the preferred device changes.

PulseAudio Release Tags

build-sys: Bump gettext dependency
Arun Raghavan: Needed for distcheck to work with a checked-in pulseaudio.pot.

build-sys: Bump version info for libpulse
Arun Raghavan: Minor implementation change since last release (we now load X11 properties only for SSH connections).

build-sys: autotools: Add meson build files to EXTRA_DIST
Arun Raghavan: As we currently still generate our tarballs using autotools, let's make sure the meson build system is distributed with the tarball.

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:

Most Popular This Year

alsa-mixer: add support for Astro A50 gaming headset
Tomasz Kontusz

device-port: queue CARD CHANGE event before update default sink
Libin Yang: In single profile mode (headphone and speaker use different PCMs), when headphone is plugged in, pa_device_port_set_available() will call pa_core_update_default_sink/source() before posting PA_SUBSCRIPTION_EVENT_CARD|PA_SUBSCRIPTION_EVENT_CHANGE to the gnome.

device-port: add type member
Jaroslav Kysela: The clients might wanna to know for which purpose is the port.

alsa: legacy card - implement device port type parser and assignment
Jaroslav Kysela

device-port: introduce available_group member
Jaroslav Kysela: In some cases, the I/O connector functionality can be shared and we cannot determine the proper purpose automatically.

stream-restore: Forget pre-14.0 stream routing
Tanu Kaskinen: Prior to commits f899d5f4669dcd536cc142cee99fe359dd8af3d6 and f62a49b8cf109c011a9818d2358beb6834e6ec25, GNOME's sound settings overwrote the routing for all entries in the stream-restore database when selecting a device.

alsa-mixer: Add support for HP Thunderbolt Dock
Kai-Heng Feng: The HP Thunderbolt Dock [1] has two separate USB cards, a headset jack and an optional module which is a speakerphone.

Add default.pa.d folder support
Sanchayan Maity: The .include meta command already supports specifying a directory and when including a directory, all files with the extension '.pa' in that directory will be parsed in alphabetical order.

alsa-mixer: add support for SteelSeries Arctis 9
Igor V. Kovalenko: Part-of: <

pactl, pacmd, cli-command: Add send-message command
Georg Chini: Part-of: <
