NAME

       pactl - Control a running PulseAudio sound server

SYNOPSIS

       pactl [options] COMMAND [ARGS ...]

       pactl --help

       pactl --version

DESCRIPTION

       pactl can be used to issue control commands to the PulseAudio sound server.

       pactl  only  exposes  a  subset  of  the  available  operations.  For the full set use the
       pacmd(1).

OPTIONS

       -h | --help
              Show help.

       --version
              Show version information.

       -s | --server=SERVER
              Choose the server to connect to.

       -n | --client-name=NAME
              Specify the client name pactl shall pass to the server when connecting.

COMMANDS

       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. If not specified, all info is listed. 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 name  or
              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 name
              or 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).

       set-default-sink SINK
              Make the specified sink (identified by its symbolic name) 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).

       set-default-source SOURCE
              Make the specified source (identified by its symbolic name) 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

       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.

       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.

       set-sink-mute SINK 1|0|toggle
              Set  the  mute  status  of  the  specified sink (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 ]"').
