PulseAudio
PulseAudio is an open-source multi-OS network sound server commonly used by modern Linux distributions.
Recent Activity
- backend-native: Add backend pointer to transport_data
Marijn Suijten: This removes the inverse/recursive dependency of backend-native on the `pa_bluetooth_discovery` struct, which is supposed to be opaque outside of `bluez5-util` in favour of the many accessor functions defined in `bluez5-util.h`. - bluetooth: add UPower backend
Dylan Van Assche: UPower provides information about the power supply and battery level of the host. - bluetooth: add AT+BIA support
Dylan Van Assche: AT+BIA is used to enable/disable CIND indicators by Bluetooth HFP spec. - shell-completion: add new subcommand get-* for zsh
hashitaku: Added to shell-completion of zsh as there is no completion for the subcommand get-*. - shell-completion: add new subcommand get-* for bash
hashitaku: Added to shell-completion of bash as there is no completion for the subcommand get-*.
Activity Earlier In The Year
- tunnel modules: Fix crash when the module was unloaded while waiting for re-init
Georg Chini: When the tunnel modules had no connection and a re-init was pending, the module could be unloaded without cancelling the pending re-init. - module-tunnel: restart module
Craig Howard: Defer the creation of the source/sink until after the TCP connection has been established. - tunnel-source-new: add restart/reconnect logic
Craig Howard: Applies the same changes as to tunnel-sink-new: defer the source creation until after the TCP connection is restablished, then attempt to restart the module on failure. - tunnel-sink-new: reinit module
Craig Howard: When configured, reinitialize the module instead of exiting. - bluetooth: Make sure there is at least one SBC frame to encode
Igor V. Kovalenko: If SBC frame plus RTP header exceeds MTU size, let block size be at least one frame to make sure bluetooth code can make progress reading and writing data. - alsa-profiles: Add NI Komplete Audio 6 MK2 profiles
Josef Haider: Part-of: < - alsa-mixer: Add analog-input path to TI PCM2902 mappings
Tanu Kaskinen: At least Behringer Xenyx 302USB doesn't have any Mic mixer elements (or indeed any capture mixer elements), so having analog-input-mic as the only input path caused the input mappings to not show up on this sound card. - loopback: Add latency prediction and Kalman filter
Georg Chini: A Kalman filter is added to further reduce noise. - loopback: Do not detect underruns during initial latency adjustments
Georg Chini: Currently module-loopback detects underruns even if sink_input_pop_cb() was not yet called twice and initial latency adjustments are active. - pulsecore: Add alternative time smoother implementation
Georg Chini: This patch adds an alternative time smoother implementation based on the theory found at
PulseAudio Release Tags
- build-sys: Bump soversion for 16.0 release
Arun Raghavan: Just a minor time smoother 2 related change in libpulse implementation. Part-of: < - bluetooth/gst: Timestamp encoding buffers according to PA clock
Marijn Suijten: Commit c6d6ca541 ("bluetooth/gst: Replace buffer accumulation in adapter with direct pull") removed the `timestamp` parameter from GStreamer transcoders due to being unused, but these should instead be propagated to the GStreamer encoding buffers. - win32: Add DACLs for directories created by system daemon
Patrick Gaskin: Part-of: < - build-sys: Fix a couple of meson warnings
Arun Raghavan: Part-of: < - 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:
Most Popular This Year
- combine-sink: Improve initial latency reports
Georg Chini: Currently, it takes one adjust time before the smoother is updated after an unsuspend. - combine-sink: Add remix modarg
Igor V. Kovalenko: When module-combine-sink is used to create virtual surround card it is expected that each slave channel receives data for exactly one combined sink channel. - loopback: Do not detect underruns during initial latency adjustments
Georg Chini: Currently module-loopback detects underruns even if sink_input_pop_cb() was not yet called twice and initial latency adjustments are active. - tunnel: Make fixed latency configurable
Georg Chini: Currently, module-tunnel uses the default fixed latency of 250ms as fixed latency. There is no reason for such a large latency. - pulsecore: Add alternative time smoother implementation
Georg Chini: This patch adds an alternative time smoother implementation based on the theory found at - loopback: Add latency prediction and Kalman filter
Georg Chini: A Kalman filter is added to further reduce noise. - combine-sink: Add rate controller
Georg Chini: This patch adds a rate controller similar to the one used in module-loopback to limit step size and maximum deviation from the base rate. - loopback: Add resampler delay to latency snapshots
Georg Chini: Part-of: < - bluetooth: Consider adapter UUIDs when evaluating profile support
João Paulo Rechi Vita: The remote device list of UUIDs reflects which profiles are supported by the remote device alone. - sink-input: Implement resampler pseudo rewinding
Georg Chini: This patch uses the two previous patches to implemnt pseudo-rewinding for the resamplers by feeding some old data into the resampler after a reset.
