NAME
pulse-cli-syntax - PulseAudio Command Line Interface Syntax SYNOPSIS
~/.config/pulse/default.pa /etc/pulse/default.pa /etc/pulse/system.pa DESCRIPTION
PulseAudio provides a simple command line language used by configuration scripts and 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 sup- ported. Note that any boolean arguments can be given positively as '1', 'on' or any word starting with the letters 't' or 'y'. Likewise, negative values can be given as '0', 'off' or any word starting with the letters 'f' or 'n'. Case is ignored. GENERAL COMMANDS
help Show a quick help on the commands available. STATUS_COMMANDS list-modules Show all currently loaded modules with their arguments. list-cards Show all currently registered cards list-sinks or list-sources Show all currently registered sinks (resp. sources). list-clients 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). MODULE MANAGEMENT
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 Unload a module specified by its index in the module list as returned by list-modules. describe-module name Give information about a module specified by its name. VOLUME COMMANDS
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' vol- ume 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. CONFIGURATION COMMANDS
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 index|name boolean Suspend (i.e. disconnect from the underlying hardware) a sink (resp. source). suspend boolean Suspend all sinks and sources. MOVING STREAMS
move-sink-input|move-source-output index sink-index|sink-name Move sink input (resp. source output) to another sink (resp. source). PROPERTY LISTS
update-sink-proplist|update-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" update-sink-input-proplist|update-source-output-proplist index properties Update the properties of a sink input (resp. source output) specified by index. The properties are specified as above. SAMPLE CACHE
list-samples 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 again. 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. KILLING CLIENTS
/STREAMS 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 server. LOG COMMANDS
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, syslog, stderr, file:PATH). set-log-time boolean Show timestamps in log messages. set-log-backtrace num-frames Show backtrace in log messages. MISCELLANEOUS COMMANDS
play-file filename sink-index|sink-name Play an audio file to a sink. dump Dump the daemon's current configuration in CLI commands. dump-volumes Debug: Shows the current state of all volumes. shared 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 META COMMANDS
In addition the the commands described above there a few meta directives supported by the command line interpreter. .include filename|folder Executes the commands from the specified script file or in all of the *.pa file within the folder. .fail and .nofail Enable (resp. disable) that following failing commands will cancel the execution of the current script file. This is a ignored when used on the interactive command line. .verbose and .noverbose Enable (resp. disable) extra verbosity. AUTHORS
