DESCRIPTION

       The PipeWire Pulseaudio server configuration file

SYNOPSIS

       $XDG_CONFIG_HOME/pipewire/pipewire-pulse.conf

       /etc/pipewire/pipewire-pulse.conf

       /usr/share/pipewire/pipewire-pulse.conf

       /usr/share/pipewire/pipewire-pulse.conf.d/

       $XDG_CONFIG_HOME/pipewire/pipewire-pulse.conf.d/

DESCRIPTION

       Configuration for PipeWire's PulseAudio-compatible daemon.

       The configuration file format and lookup logic is the same as for pipewire.conf(5).

       Drop-in configuration files pipewire-pulse.conf.d/*.conf can be used, and are recommended. See
       pipewire.conf(5).

CONFIGURATION FILE SECTIONS

       stream.properties
           Dictionary. These properties configure the PipeWire Pulseaudio server properties.

       stream.rules
           Dictionary. These properties configure the PipeWire Pulseaudio server properties.

       pulse.properties
           Dictionary. These properties configure the PipeWire Pulseaudio server properties.

       pulse.cmd
           Array of dictionaries. A set of commands to be executed on startup.

       pulse.rules
           Array of dictionaries. A set of match rules and actions to apply to clients.

       See libpipewire-module-protocol-pulse(7) for the detailed description.

       In addition, the PipeWire context configuration sections may also be specified, see pipewire.conf(5).

STREAM PROPERTIES

       The stream.properties section contains properties for streams created by the pipewire-pulse server.

       Available options are described in pipewire-client.conf(5) stream.properties.

       Some of these properties map to the PulseAudio /etc/pulse/default.pa config entries as follows:

       PulseAudio   PipeWire   Notes    remixing-use-all-sink-channels   channelmix.upmix   remixing-produce-lfe
       channelmix.lfe-cutoff   Set to > 0 to enable    remixing-consume-lfe   channelmix.mix-lfe   lfe-
       crossover-freq   channelmix.lfe-cutoff

   Example
       # ~/.config/pipewire/pipewire-pulse.conf.d/custom.conf

       stream.properties = {
           #node.latency = 1024/48000
           #node.autoconnect = true
           #resample.disable = false
           #resample.quality = 4
           #monitor.channel-volumes = false
           #channelmix.disable = false
           #channelmix.min-volume = 0.0
           #channelmix.max-volume = 10.0
           #channelmix.normalize = false
           #channelmix.mix-lfe = true
           #channelmix.upmix = true
           #channelmix.upmix-method = psd  # none, simple
           #channelmix.lfe-cutoff = 150.0
           #channelmix.fc-cutoff = 12000.0
           #channelmix.rear-delay = 12.0
           #channelmix.stereo-widen = 0.0
           #channelmix.hilbert-taps = 0
           #dither.noise = 0
           #dither.method = none # rectangular, triangular, triangular-hf, wannamaker3, shaped5
           #debug.wav-path = ""
       }

STREAM RULES

       The stream.rules section works the same as pipewire-client.conf(5) stream.rules.

PULSEAUDIO PROPERTIES

       For pulse.properties section, see libpipewire-module-protocol-pulse(7) for available options.

PULSEAUDIO RULES

       For each client, a set of rules can be written in pulse.rules section to configure quirks of the client
       or to force some pulse specific stream configuration.

       The general look of this section is as follows and follows the layout of match rules, see pipewire(1).

       See libpipewire-module-protocol-pulse(7) for available options.

   Example
       # ~/.config/pipewire/pipewire-pulse.conf.d/custom.conf

       pulse.rules = [
           {
               # skype does not want to use devices that don't have an S16 sample format.
               matches = [
                    { application.process.binary = "teams" }
                    { application.process.binary = "teams-insiders" }
                    { application.process.binary = "skypeforlinux" }
               ]
               actions = { quirks = [ force-s16-info ] }
           }
           {
               # speech dispatcher asks for too small latency and then underruns.
               matches = [ { application.name = "~speech-dispatcher*" } ]
               actions = {
                   update-props = {
                       pulse.min.req          = 1024/48000     # 21ms
                       pulse.min.quantum      = 1024/48000     # 21ms
                   }
               }
           }
       ]

PULSEAUDIO COMMANDS

       As part of the server startup procedure you can execute some additional commands with the pulse.cmd
       section in pipewire-pulse.conf.

       # ~/.config/pipewire/pipewire-pulse.conf.d/custom.conf

       pulse.cmd = [
           { cmd = "load-module" args = "module-always-sink" flags = [ ] }
           { cmd = "load-module" args = "module-switch-on-connect" }
           { cmd = "load-module" args = "module-gsettings" flags = [ "nofail" ] }
       ]
       ...

       Additional commands can also be run via the context.exec section, see pipewire.conf(5).

       Supported commands:

       load-module
           Load the specified Pulseaudio module on startup, as if using pactl(1) to load the module.
