When supplied as arguments to the commands below, the special names \@DEFAULT_SINK@, \@DEFAULT_SOURCE@ and \@DEFAULT_MONITOR@
can be used to specify the default sink, source and monitor respectively.
stat
Dump a few statistics about the memory usage of the PulseAudio daemon.
info
Dump some info about the PulseAudio daemon.
list [short ] [TYPE ]
Dump all currently loaded modules, available sinks, sources, streams, etc. TYPE must be one of:
modules, sinks, sources, sink-inputs, source-outputs, clients, samples, cards, message-handlers. If not specified, all info is listed
with the exception of the message-handlers. If short is given, output is in a tabular format, for easy parsing by scripts.
exit
Asks the PulseAudio server to terminate.
upload-sample FILENAME [NAME ]
Upload a sound from the specified audio file into
the sample cache. The file types supported are those understood
by libsndfile . The sample in the cache is named
after the audio file, unless the name is explicitly
specified.
play-sample NAME [SINK ]
Play the specified sample from the sample cache. It
is played on the default sink, unless the symbolic name or the
numerical index of the sink to play it on is
specified.
remove-sample NAME
Remove the specified sample from the sample cache.
load-module NAME [ARGUMENTS ... ]
Load the specified module with the specified arguments into the running sound server.
Prints the numeric index of the module just loaded to STDOUT. You can use it to unload the module later.
unload-module ID|NAME
Unload the module instance identified by the specified numeric index or unload all modules by the specified name.
move-sink-input ID SINK
Move the specified playback stream (identified by its numerical index) to the specified sink (identified by its symbolic name or numerical index).
move-source-output ID SOURCE
Move the specified recording stream (identified by its numerical index) to the specified source (identified by its symbolic name or numerical index).
suspend-sink SINK true|false
Suspend or resume the specified sink (which may be
specified either by its symbolic name or numerical index), depending whether true
(suspend) or false (resume) is passed as last argument. Suspending
a sink will pause all playback. Depending on the module implementing
the sink this might have the effect that the underlying device is
closed, making it available for other applications to use. The exact
behaviour depends on the module.
suspend-source SOURCE true|false
Suspend or resume the specified source (which may be
specified either by its symbolic name or numerical index), depending whether true
(suspend) or false (resume) is passed as last argument. Suspending
a source will pause all capturing. Depending on the module implementing
the source this might have the effect that the underlying device is
closed, making it available for other applications to use. The exact
behaviour depends on the module.
set-card-profile CARD PROFILE
Set the specified card (identified by its symbolic name or numerical index) to the specified profile (identified by its symbolic name).
get-default-sink
Returns the symbolic name of the default sink.
set-default-sink SINK
Make the specified sink (identified by its symbolic name or numerical index) the default sink.
set-sink-port SINK PORT
Set the specified sink (identified by its symbolic name or numerical index) to the specified port (identified by its symbolic name).
get-default-source
Returns the symbolic name of the default source.
set-default-source SOURCE
Make the specified source (identified by its symbolic name or numerical index) the default source.
set-source-port SOURCE PORT
Set the specified source (identified by its symbolic name or numerical index) to the specified port (identified by its symbolic name).
set-port-latency-offset CARD PORT OFFSET
Set a latency offset to a specified port (identified by its symbolic name) that belongs to a card (identified by its symbolic name or numerical index).
OFFSET is a number which represents the latency offset in microseconds
get-sink-volume SINK
Get the volume of the specified sink (identified by its symbolic name or numerical index) displayed in the same format as the `info` command.
set-sink-volume SINK VOLUME [VOLUME ...]
Set the volume of the specified sink (identified by its symbolic name or numerical index).
VOLUME can be specified as an integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a percentage
(e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If the volume specification start with a + or - the volume
adjustment will be relative to the current sink volume. A single volume value affects all channels; if multiple
volume values are given their number has to match the sink's number of channels.
get-source-volume SOURCE
```
Get the volume of the specified source (identified by its symbolic name or numerical index) displayed in the same format as the `info` command.
set-source-volume SOURCE VOLUME [VOLUME ...]
Set the volume of the specified source (identified by its symbolic name or numerical index).
VOLUME can be specified as an integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a percentage
(e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If the volume specification start with a + or - the volume
adjustment will be relative to the current source volume. A single volume value affects all channels; if multiple
volume values are given their number has to match the source's number of channels.
set-sink-input-volume INPUT VOLUME [VOLUME ...]
Set the volume of the specified sink input (identified by its numerical index).
VOLUME can be specified as an integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a percentage
(e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If the volume specification start with a + or - the volume
adjustment will be relative to the current sink input volume. A single volume value affects all channels; if multiple
volume values are given their number has to match the sink input's number of channels.
set-source-output-volume OUTPUT VOLUME [VOLUME ...]
Set the volume of the specified source output (identified by its numerical index).
VOLUME can be specified as an integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a percentage
(e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If the volume specification start with a + or - the volume
adjustment will be relative to the current source output volume. A single volume value affects all channels; if multiple
volume values are given their number has to match the source output's number of channels.
get-sink-mute SINK
Get the mute status of the specified sink (identified by its symbolic name or numerical index).
set-sink-mute SINK 1|0|toggle
Set the mute status of the specified sink (identified by its symbolic name or numerical index).
get-source-mute SOURCE
Get the mute status of the specified source (identified by its symbolic name or numerical index).
set-source-mute SOURCE 1|0|toggle
Set the mute status of the specified source (identified by its symbolic name or numerical index).
set-sink-input-mute INPUT 1|0|toggle
Set the mute status of the specified sink input (identified by its numerical index).
set-source-output-mute OUTPUT 1|0|toggle
Set the mute status of the specified source output (identified by its numerical index).
set-sink-formats SINK FORMATS
Set the supported formats of the specified sink (identified
by its numerical index) if supported by the sink. FORMATS is
specified as a semi-colon (;) separated list of formats in the form
'encoding[, key1=value1, key2=value2, ...]' (for example, AC3 at 32000,
44100 and 48000 Hz would be specified as
'ac3-iec61937, format.rate = "[ 32000, 44100, 48000 ]"'). See
https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/SupportedAudioFormats/
for possible encodings.

Send a message to the specified recipient object. If applicable an additional string containing
message parameters can be specified. A string is returned as a response to the message. For available messages
