NAME
pipewire-pulse-modules − PipeWire Pulseaudio modules
DESCRIPTION
PipeWire’s Pulseaudio emulation implements several Pulseaudio modules. It only supports its own built-in modules, and cannot load external modules written for Pulseaudio.
LOADING MODULES
The built-in modules can be loaded using Pulseaudio client programs, for example pactl load-module <module-name> <module-options>. They can also added to pipewire-pulse.conf, typically by a drop-in file in ~/.config/pipewire/pipewire-pulse.conf.d/ containing the module name and its arguments
~/.config/pipewire/pipewire−pulse.conf.d/custom.conf
pulse.cmd = [
{ cmd = “load−module” args = “module−null−sink sink_name=foo” flags = [ ] }
]
To list all modules currently loaded, with their arguments:
pactl list modules
For a short list of loaded modules:
pactl list modules short
Modules may be unloaded using either the module-name or index number:
pactl load−module <module−name> <parameters>
pactl unload−module <module−name|index#>
COMMON MODULE OPTIONS
Most modules that create streams/devices support the following properties:
sink_name, source_name
Name for the sink (resp. source). Allowed characters in the name are a-z, A-Z, numbers, period (.) and underscore (_). The length must be 1-128 characters.
format
The sample format. The supported audio formats are:
PCM
| • | u8: unsigned 8-bit integer | ||
| • | aLaw: A-law encoded 8-bit integer | ||
| • | uLaw: μ-law encoded 8-bit integer | ||
| • | s16le: signed 16-bit little-endian integer | ||
| • | s16be: signed 16-bit big-endian integer | ||
| • | s16, s16ne: native-endian aliases for s16le or s16be | ||
| • | s16re: reverse-endian alias for s16le or s16be | ||
| • | float32le: 32-bit little-endian float | ||
| • | float32be: 32-bit big-endian float | ||
| • | float32, float32ne: native-endian aliases for float32le or float32be | ||
| • | float32re: reverse-endian alias for float32le or float32be | ||
| • | s32le: signed 32-bit little-endian integer | ||
| • | s32be: signed 32-bit big-endian integer | ||
| • | s32, s32ne: native-endian aliases for s32le or s32be | ||
| • | s32re: reverse-endian alias for s32le or s32be | ||
| • | s24le: signed 24-bit little-endian integer (note: ALSA calls this “S24_3LE”) | ||
| • | s24be: signed 24-bit big-endian integer (note: ALSA calls this “S24_3BE”) | ||
| • | s24, s24ne: native-endian aliases for s24le or s24be | ||
| • | s24re: reverse-endian alias for s24le or s24be | ||
| • | s24-32le: signed 24-bit little-endian integer, packed into a 32-bit integer so that the 8 most significant bits are ignored (note: ALSA calls this “S24_LE”) | ||
| • | s24-32be: signed 24-bit big-endian integer, packed into a 32-bit integer so that the 8 most significant bits are ignored (note: ALSA calls this “S24_BE”) | ||
| • | s24-32, s24-32ne: native-endian aliases for s24-32le or s24-32be | ||
| • | s24-32re: reverse-endian alias for s24-32le or s24-32be |
Compressed audio formats
Below is a list of all supported compressed formats. The code at the beginning of each line is used whenever a textual identifier for a format is needed (for example in configuration files or on the command line). The formats whose identifier ends with -iec61937 have to be wrapped in IEC 61937 frames, which makes the compressed audio behave more like normal PCM audio.
| • | ac3-iec61937: Dolby Digital (DD / AC-3 / A/52) | ||
| • | eac3-iec61937: Dolby Digital Plus (DD+ / E-AC-3) | ||
| • | mpeg-iec61937: MPEG-1 or MPEG-2 Part 3 (not MPEG-2 AAC) | ||
| • | dts-iec61937: DTS | ||
| • | mpeg2-aac-iec61937: MPEG-2 AAC (supported since PulseAudio 4.0) | ||
| • | truehd-iec61937: Dolby TrueHD (added in PulseAudio 13.0, but doesn’t work yet in practice) | ||
| • | dtshd-iec61937: DTS-HD Master Audio (added in PulseAudio 13.0, but doesn’t work yet in practice) | ||
| • | pcm: PCM (not a compressed format, but listed here, because pcm is one of the recognized encoding identifiers) | ||
| • | any: (special identifier for indicating that any encoding can be used) |
rate
The sample rate.
channels
Number of audio channels.
channel_map
A channel map. A list of comma-separated channel names. The currently defined channel names are: left, right, mono, center, front-left, front-right, front-center, rear-center, rear-left, rear-right, lfe, subwoofer, front-left-of-center, front-right-of-center, side-left, side-right, aux0, aux1 to aux15, top-center, top-front-left, top-front-right, top-front-center, top-rear-left, top-rear-right, top-rear-center
sink_properties, source_properties
Set additional properties of the sink/source. For example, you can set the description directly when the module is loaded by setting this parameter.
load−module module−alsa−sink sink_name=headphones sink_properties=device.description=Headphones
