# 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.
|
||||
\include{doc} pulse-modules.inc
|
||||
|
||||
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
|
||||
|
||||

||||
{ cmd = "load-module" args = "module-null-sink sink_name=foo" flags = [ ] }

# 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
|

```
|

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
|
||||
```
