PulseAudio 6.0 Release Notes

Changes at a Glance

  • BlueZ 5 native HSP (headset) support
  • BlueZ 5 HFP (hands-free) profile support via oFono
  • systemd socket activation support
  • Better support for multichannel and 2.1 profiles
  • Remap optimisations
  • Many minor improvements, bug fixes, and i18n updates

Notes for Application Developers

New function in libpulse: pa_stream_write_ext_free(). The function allows more flexible use of free callbacks than the regular pa_stream_write() function. This is useful if an audio buffer is part of a bigger structure that needs to be freed or unreferenced when the audio buffer is no longer needed.

We now have Vala bindings for libpulse-simple.

Notes for Packagers

When building PulseAudio, it's possible to choose between "native" and "ofono" BlueZ 5 headset backends. They can be both enabled, but only one can be used at runtime. If you only need to support a bluetooth audio stack with oFono, then it's advisable to disable the native backend when building PulseAudio. Similarly, if you don't need to support oFono, then it's best to disable the oFono backend. If you need to support both alternatives, then you have to enable both. The runtime decision which to use is done via the "headset" argument of module-bluetooth-discover.

The native HSP backend for BlueZ 5 depends on libbluetooth. It's a header dependency only, so the actual library doesn't need to be present at runtime.

The oFono HFP backend for BlueZ 5 naturally introduces a runtime dependency on oFono. The minimum supported oFono version is 1.13.

The minimum json-c version has been bumped to 0.11.

The libsamplerate based resamplers are now deprecated, because they offer no particular advantage over speex. Packagers can drop the dependency to libsamplerate, unless they specifically want to keep enabling the libsamplerate based resamplers for some reason.

extra-hdmi.conf, which was present in 5.0 and a few versions before that, has been merged with default.conf. The udev rule has been updated accordingly, but these are typically only read at boot time, so in some cases your sound card might not to be detected. We suggest you do one of the following to fix this transitional problem:

  • Reboot your computer, or
  • Run "udevadm control --reload" and then "udevadm trigger" (as root), or
  • Create a symlink from extra-hdmi.conf to default.conf.

start-pulseaudio-kde has been merged into start-pulseaudio-x11 and pulseaudio-kde.desktop has been removed. The only thing that those KDE specific files did was to load module-device-manager at session startup, and that is now handled in start-pulseaudio-x11 (it's still done only for KDE sessions).

start-pulseaudio-x11 doesn't any more start PulseAudio explicitly, because explicit starting conflicts with using systemd to start the user instance. When systemd isn't used, the regular autospawning functionality will still make PulseAudio start. However, if the user has disabled autospawning in client.conf, then PulseAudio will not be started at all by start-pulseaudio-x11 (which may or may not be what the user wants).

Changes in More Detail

Bluetooth HSP/HFP support with BlueZ 5

PulseAudio now has partial support for the bluetooth HSP (headset) and HFP (hands-free) profiles with BlueZ 5. There are two mutually exclusive backends for HSP/HFP: "native" and "oFono". Some limitations remain, and the limitations are different depending on the backend:

The native backend only supports HSP, not HFP. That's usually not a big issue, because most devices support both HSP and HFP, so it's enough to support only one profile to get audio working. Another limitation in the native backend is that it doesn't support the "headset role", which means that the use case of connecting a PC to a mobile phone, so that the PC pretends to be a headset, isn't supported.

The oFono backend in turn only supports HFP, and not HSP. oFono supports audio only with the "hands-free" role of HFP, which means that the problem is opposite to the native backend case: a mobile phone can be connected to a PC with the PC acting as a headset or other hands-free device, but connecting a headset to the PC doesn't work. Also, volume control doesn't work as well as it could (PulseAudio doesn't tell the connected device what the volume is at PulseAudio's end, so PulseAudio and the connected device handle the device volume independently, which is prone to cause confusion).

Since the oFono and native backends are currently not overlapping, it would be possible to have both backends active at the same time, but there is not consensus about whether this is a good way forward or not. For now, you can apply this patch if you need this functionality.

systemd socket activation support

PulseAudio now supports systemd's socket activation. There's support only for unix sockets, though; support for TCP sockets will come later. PulseAudio ships with a ready-made socket file for starting the user instance, but it's not generally advisable to enable it, because doing so will likely prevent PulseAudio from accessing the D-Bus session bus, crippling some features that depend on the session bus. It's expected that in the future, systems that use systemd will replace the session bus with a user bus, at which point the socket activation support in PulseAudio will become usable more widely.

Here's the list of things in PulseAudio that depend on the session bus, so if you want to try the socket activation and you don't somehow set up the session bus address appropriately, these things will break:

  • module-jackdbus-detect. Breaking that breaks the automatic discovery of a running JACK server.
  • The device reservation protocol. Breaking that breaks clean device handover from PulseAudio to JACK.
  • Server tracking in libpulse. Clients can set up libpulse so that if the PulseAudio server isn't running when they try to connect, the connection attempt will be continued when the server starts and advertises itself in the session bus. This feature is rarely needed, so not a big loss.
  • module-rygel-media-server. Breaking that breaks PulseAudio's integration with Rygel.
  • The server lookup service of the D-Bus protocol. Breaking that breaks pretty much all applications that use PulseAudio's D-Bus protocol, because they can't figure out where the server's D-Bus socket is. There aren't many applications using the D-Bus protocol, though, so this is not a big loss in most cases.

Performance improvements

PulseAudio has since long supported transferring audio data between clients and server through SHM (shared memory), whereas the packet metadata was sent through a unix socket. As of 6.0 we also support transferring packet metadata through two SHM ringbuffers, one in each direction. For signalling that a new packet has arrived, we use eventfds. (There is also an optimisation layer on top of the eventfd that tries to avoid writing to the eventfd in case no one is currently waiting.) This is not so much for saving memory copies, but to save syscalls. This new protocol mechanism is called srbchannel, short for "Shared RingBuffer channel". Some unscientific benchmarks show that this can save us ~10% - 25% of CPU power in low latency use cases, half of that being on the client side. Due to unresolved bugs, srbchannel is not enabled by default in this release. The feature can be enabled by passing "srbchannel=true" to module-native-protocol-unix.

Channel remapping has been optimized by replacing the generic implementation with specialized code for certain cases (implementations are done both in C and ARM NEON).

ARM NEON implementation has been added for the special cases of mixing two 16-bit streams when both have 1, 2 or 4 channels.

module-combine-sink now supports dynamic latency, so that applications that require low latency may work properly also with a combine sink.

Better support for multichannel and 2.1 profiles

Some multichannel cards, including cards supported by the new Firewire ALSA drivers (merged in Linux 3.16) and some USB cards can only be opened in multichannel mode, e g 14 outputs and 10 inputs. If all existing attempts to open the device fails, we make a last attempt where the driver can choose number of channels freely. A default channel map for these channels is assumed.

7.1 audio support for HDMI has been added.

Also, ALSA 1.0.28 added better support for surround2.1 profiles. We now support this new syntax (surround21:card) where available.

Utility changes

pactl now supports setting different volume for each channel of a device or stream.

Multiple instances of JACK sinks and sources

Previously it was not possible to load two instances of module-jack-sink or module-jack-source. That limitation was entirely artificial and didn't make much sense, so the limitation has now been removed.

New argument for module-switch-on-connect

module-switch-on-connect now accepts a new boolean argument: "only_from_unavailable". If only_from_unavailable is false (the default), the module behaviour is the same as before (switch to new devices unconditionally), but if it's true, the device switch is done only if the default device was previously unavailable.
