Notes for end users

Added support for Dolby TrueHD and DTS-HD Master Audio

It's now possible to play Dolby TrueHD and DTS-HD Master Audio encoded audio in passthrough mode. Players need to be updated to expose support for these formats.

Improved 5.1 surround channel routing

When applications play 5.1 surround audio, they have to tell PulseAudio the channel map of the content. The established naming standards for various surround setups aren't entirely consistent: what is called "rear" speakers in 5.1 setups is called "side" in 7.1 speaker setups. In the 7.1 arrangement the "rear" speakers are further back. With 5.1 content applications have to decide whether to use the "side" or "rear" channels, and it varies across applications which is used. PulseAudio used to handle the channel routing correctly only if the application chose to use the "rear" channels with 5.1 content. Applications using the "side" channels got their audio badly remixed, because PulseAudio determined that the 5.1 speaker system doesn't have any "side" speakers. Now it doesn't matter which alternative the application picks, PulseAudio treats both cases identically when the user has a 5.1 speaker setup (with a 7.1 setup there is still a difference which channel pair gets used).

Improved initial card profile selection for ALSA cards

When a new card shows up (during PulseAudio startup or hotplugged), PulseAudio needs to pick the initial profile for the card. Unavailable profiles shouldn't be picked, but module-alsa-card sometimes marked unavailable profiles as available, causing bad initial profile choices. Specifically, if a profile contains a sink and a source, and only one of them is available, the profile should be marked as unavailable, but previously it was marked as available. As a result PulseAudio might pick a profile with a non-working output. That's now fixed.

Automatically switch away from unavailable card profiles

PulseAudio has for a long time supported switching the sink or source port when the port becomes unavailable, for example switching to laptop speakers when headphones are detached. Now similar switching is implemented for card profiles when the current profile becomes unavailable. A common case is a HDMI profile that becomes unavailable when a monitor is detached. Playback should now automatically move to somewhere else when a HDMI monitor is detached.

Bluetooth card profile choices aren't persistent any more by default

Which profile to use with bluetooth is highly context dependent (HSP/HFP for phone calls, A2DP for everything else), so there's not much point in saving user's profile choices. It's better to just use A2DP by default and switch to HSP when necessary (automatically when possible). It's still possible to enable persistent profile choices by passing "restore_bluetooth_profile=true" as an argument to module-card-restore.

Added support for some SteelSeries Arctis 5 USB headsets

The Arctis headsets are unusual in that they provide separate outputs with separate volume controls for speech and other audio (which is useful with gaming), which requires some custom configuration in PulseAudio. PulseAudio 12.0 added support for the Arctis 7 headset, and now PulseAudio 13.0 adds support for the Arctis 5 headset too.

We are still discovering new USB product IDs for this series, and support for more headsets will be coming.

Removed KDE specific routing configuration

module-device-manager was created a long time ago to serve the needs of the KDE project's vision for how audio management should work (most notably audio routing), and PulseAudio's autostart system was configured to load module-device-manager when a KDE session is started. The module has had various issues over time, especially when used in combination with module-switch-on-connect, and there hasn't been enough developer interest for fixing the issues. There have been occasional requests from users to disable module-device-manager, but since KDE has depended on the module for some of its audio UI, we have kept the module enabled. With newer KDE versions the dependency on the module is finally gone, however, so now PulseAudio won't load the module by default any more if the startup script detects that the KDE version is new enough.

New information collection script for bug reports: pa-info

PulseAudio comes now with a program called "pa-info", which is a script that runs various commands to gather comprehensive information about the system's audio setup. The script is inspired by ALSA's alsa-info script (and if alsa-info is available, it will also be run by pa-info). The script is intended to reduce the need to repeatedly ask for various bits of information when investigating bug reports.

New "max_latency_msec" module argument for module-loopback

The "max_latency_msec" module argument can be used to set an upper limit for the loopback latency. By default the latency will automatically increase if there are underruns, but if keeping the latency below a certain limit is more important than the absence of glitches, then this option is useful.

New "fast_adjust_threshold_msec" module argument for module-loopback

If the loopback for some reason gathers a lot of audio in its internal queue, it will take a long time before the loopback gradually adjusts its latency back to the target latency. This can happen for example during a suspend/resume cycle, if the loopback's output device takes more time to initialize than the input device. The new "fast_adjust_threshold_msec" module argument can be used to specify a threshold of difference between the actual latency and the target latency, and if the threshold is exceeded, the loopback immediately adjusts to the target latency by dropping audio from its queue.

New "stream_name" module argument for module-rtp-send

module-rtp-send has so far used "PulseAudio RTP Stream on <address>" as the name for the RTP stream that it creates. If a different name is desired, it can be set with the new "stream_name" module argument.

Fixed S/PDIF for CMEDIA USB2.0 High-Speed True HD Audio

The "CMEDIA USB2.0 High-Speed True HD Audio" sound card (probably a generic chip used in several products) uses unusual device indexes for S/PDIF, which is why the default ALSA USB-Audio configuration doesn't work. PulseAudio now has custom configuration to deal with the card.

Use source sample spec and channel map by default in module-loopback

Previously module-loopback used the sink sample spec and channel map by default, which caused unnecessary resampling, because the sink side of the loopback will anyway be resampled due to the adaptive resampling, and if the sink parameters are different than the source parameters, also the source side needed resampling. Now that we default to the source parameters, the source side of the loopback doesn't need resampling.

module-role-cork and module-role-ducking can now use recording streams as triggers

module-role-cork and module-role-ducking are used to pause or attenuate streams based on the existence of other streams and their media role property. So far it has only been possible to use playback streams as the trigger streams, now also recording streams can be used. In order to not change the behaviour of existing configurations, recording stream triggers have to be explicitly enabled by setting the "use_source_trigger=true" module argument.

New "avoid_resampling" module argument for module-udev-detect and module-alsa-card

The global "avoid-resampling" option in daemon.conf can now be overridden for all ALSA cards in module-udev-detect and for a specific card in module-alsa-card with the "avoid_resampling" module argument. This isn't very useful for end users currently, though, because configuring the option per-card is rather complicated. The new feature is mainly useful for system integrators who want to set a fixed sample rate for the "main" sound card (because that's the rate they test, and other sample rates are a risk), but want to allow e.g. USB sound cards to use any sample rate. To do that, daemon.conf should have "avoid-resampling=yes" set, and udev needs to be configured to set the PULSE_IGNORE variable for the main sound card so that module-udev-detect doesn't load the card, and then module-alsa-card needs to be explicitly loaded for the main sound card in default.pa with "avoid_resampling=no".

"avoid_resampling" also tries to avoid format conversion if the ALSA device supports it

In addition to reconfiguring the sample rate on the ALSA device to avoid resampling, we also try to reconfigure the sample format. This would allow, for example, switching between 16- and 24-bit audio based on the file being played if the hardware supports it.

Added support for non-PCM formats in module-null-sink

It's now possible to play compressed audio formats to a null sink. This is mainly useful for developers testing passthrough implementation in applications or in PulseAudio itself. The new "format" module argument of module-null-sink can be used to specify which formats the null sink should accept (by default only PCM is accepted). See the module documentation for more details.

More efficient channel remapping in some cases for 32-bit streams

If the sound card uses 32-bit integer samples (in the system's native endianness) and a stream with the same sample format is connected to the sound card, PulseAudio can now do channel remapping without converting the audio to floating point samples during the processing. This improves performance significantly (for this case, which is not a very common case).

Removed the "latency_time" option from module-null-source

The option didn't make sense, because module-null-source uses dynamic latency (recording streams can specify their desired latency and the source adapts to that). The option value did have some effect on the operation of module-null-source, but that was only because the implementation was buggy. After the implementation was fixed, the latency_time value wasn't used at all.

Notes for application developers

New function to enable realtime scheduling for client threads

pa_thread_make_realtime() is a new utility function that can be used to enable realtime scheduling for the calling thread. That is useful if the application developer doesn't want to figure out the operating system's APIs by themself. The function uses RealtimeKit when available, otherwise operating system specific low-level interfaces are used.

New convenience functions for getting parameters from pa_format_info

Reading the sample rate, sample format, channel count and channel map parameters from pa_format_info can now be done with pa_format_info_get_rate(), pa_format_info_get_sample_format(), pa_format_info_get_channels() and pa_format_info_get_channel_map(), respectively.

New function for pa_threaded_mainloop to run a callback in the mainloop thread without the mainloop lock being held

pa_threaded_mainloop_once_unlocked() can be called from any thread to schedule a callback to be called in the mainloop thread. The callback will be called without the mainloop lock being held, which is unusual and can be unsafe. This was added, because the application might be dealing with locking its own objects in addition to the mainloop thread itself. In this case, it might need to control the locking order of the two, to match the order in other threads, as it might not always be able to allow for its objects to be locked after the mainloop thread lock.

Const-ification of parameters across headers

A number of parameters across heads have been marked with the "const" qualifier where applicable. This should not have a visible impact, other than in some corner cases. We are aware that the QT project uses a mix of their own declarations and system headers (there is a bug to track this).

Notes for packagers

Removed BlueZ 4 support

BlueZ 5.0 was released in 2012, and the 4.x series has been unmaintained since then. Now PulseAudio has dropped support for BlueZ 4.

Dropped intltool

PulseAudio now uses a newer gettext version that removes the need to use intltool. The required minimum gettext version is now 0.19.3.

Introduction of the Meson build system

The plan is to move to a Meson based build system. This should be considered to be in "beta". Packagers are encourage to use it and report issues to allow for a smooth migration. The meson build does not use any compiler optimisations by default, so you will need to specify them manually (for example, with the --optimization argument) to not have a performance regression (this can be ~10x for some compute-intensive tasks on ARM-based systems). The autotools build uses -O2 by default.

New build option for improving build reproducibility

By default PulseAudio can be run from the build directory without installing, and in order to support this the build directory needs to be stored in the compiled code. This is not good for reproducible builds, and this feature can now be disabled with the "--disable-running-from-build-tree" configure option or the "running-from-build-tree" Meson build option.
