          pulse-cli-syntax - PulseAudio Command Line Interface Syntax




          PulseAudio provides a simple command line language used by
          configuration scripts, the pacmd interactive shell, and the
          modules module-cli and module-cli-protocol-{unix,tcp}. Empty
          lines and lines beginning with a hashmark (#) are silently
          ignored. Several commands are supported.

          Note that any boolean arguments can be given positively as
          '1', 't', 'y', 'true', 'yes' or 'on'. Likewise, negative
          values can be given as '0', 'f', 'n', 'false', 'no' or
          'off'. Case is ignored.

          help Show a quick help on the commands available.

               Show all currently loaded modules with their arguments.

               Show all currently registered cards

          list-sinks or list-sources
               Show all currently registered sinks (resp. sources).

               Show all currently active clients.

          list-sink-inputs or list-source-outputs
               Show all currently active inputs to sinks a.k.a.
               playback streams (resp. outputs of sources a.k.a.
               recording streams).

          stat Show some simple statistics about the allocated memory
               blocks and the space used by them.

          info or ls or list
               A combination of all status commands described above
               (all three commands are synonyms).

          load-module name [arguments...]
               Load a module specified by its name and arguments. For
               most modules it is OK to be loaded more than once.

          unload-module index|name
               Unload a module, specified either by its index in the
               module list or its name.

          describe-module name
               Give information about a module specified by its name.

          set-sink-volume|set-source-volume index|name volume
               Set the volume of the specified sink (resp. source).
               You may specify the sink (resp. source) either by its
               index in the sink/source list or by its name. The
               volume should be an integer value greater or equal than
               0 (muted). Volume 65536 (0x10000) is 'normal' volume
               a.k.a. 100%. Values greater than this amplify the audio
               signal (with clipping).

          set-sink-mute|set-source-mute index|name boolean
               Mute or unmute the specified sink (resp. source). You
               may specify the sink (resp. source) either by its index
               or by its name. The mute value is either 0 (not muted)
               or 1 (muted).

          set-sink-input-volume|set-source-output-volume index volume
               Set the volume of a sink input (resp. source output)
               specified by its index. The same volume rules apply as
               with set-sink-volume.

          set-sink-input-mute|set-source-output-mute index boolean
               Mute or unmute a sink input (resp. source output)
               specified by its index. The same mute rules apply as
               with set-sink-mute.

          set-default-sink|set-default-source index|name
               Make a sink (resp. source) the default. You may specify
               the sink (resp. source) by its index in the sink (resp.
               source) list or by its name.

               Note that defaults may be overridden by various policy
               modules or by specific stream configurations.

          set-card-profile index|name profile-name
               Change the profile of a card.

          set-sink-port|set-source-port index|name port-name
               Change the profile of a sink (resp. source).

          set-port-latency-offset card-index|card-name port-
               name offset
               Change the latency offset of a port belonging to the
               specified card

          suspend-sink|suspend-source name|index true|false
               Suspend or resume the specified sink or 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 sink will pause
               all playback and suspending a source will pause all
               capturing. Depending on the module implementing the
               sink or 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.

          suspend boolean
               Suspend all sinks and sources.

          move-sink-input|move-source-output index sink-index|sink-
               Move sink input (resp. source output) to another sink
               (resp. source).

               proplist index|name properties
               Update the properties of a sink (resp. source)
               specified by name or index. The property is specified
               as e.g. device.description="My Preferred Name"

               proplist index
               Update the properties of a sink input (resp. source
               output) specified by index. The properties are
               specified as above.

               Lists the contents of the sample cache.

          play-sample name sink-index|sink-name
               Play a sample cache entry to a sink.

          remove-sample name
               Remove an entry from the sample cache.

          load-sample name filename
               Load an audio file to the sample cache.

          load-sample-lazy name filename
               Create a new entry in the sample cache, but don't load
               the sample immediately. The sample is loaded only when
               it is first used. After a certain idle time it is freed

          load-sample-dir-lazy path
               Load all entries in the specified directory into the
               sample cache as lazy entries. A shell globbing
               expression (e.g. *.wav) may be appended to the path of
               the directory to add.

          kill-client index
               Remove a client forcibly from the server. There is no
               protection against the client reconnecting immediately.

          kill-sink-input|kill-source-output index
               Remove a sink input (resp. source output) forcibly from
               the server. This will not remove the owning client or
               any other streams opened by the same client from the

          set-log-level numeric-level
               Change the log level.

          set-log-meta boolean
               Show source code location in log messages.

          set-log-target target
               Change the log target (null, auto, journal, syslog,
               stderr, file:PATH, newfile:PATH).

          set-log-time boolean
               Show timestamps in log messages.

          set-log-backtrace num-frames
               Show backtrace in log messages.

          play-file filename sink-index|sink-name
               Play an audio file to a sink.

          dump Dump the daemon's current configuration in CLI

               Debug: Shows the current state of all volumes.

               Debug: Show shared properties.

          exit Terminate the daemon. If you want to terminate a CLI
               connection ("log out") you might want to use ctrl+d

          In addition to the commands described above there are a few
          meta directives supported by the command line interpreter.

               all of the *.pa files within the folder.
               Executes the commands from the specified script file or in

     paths are resolved using the module directory as the base. By
     using an absolute path, the existence of other files can be
     checked as well.

     command. Nesting conditional commands is not supported.
          A block of commands is delimited by an .else or .endif meta
