pactl(1) General Commands Manual pactl(1) 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. -f | --format=FORMAT Choose output format, available options are "text" or "json". -n | --client-name=NAME Specify the client name pactl shall pass to the server when con- necting. COMMANDS 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 excep- tion 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 libsnd- file. The sample in the cache is named after the audio file, un- less 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 in- dex 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 ei- ther 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 mod- ule implementing the sink this might have the effect that the underlying device is closed, making it available for other ap- plications 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 argu- ment. 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 nu- merical index) to the specified profile (identified by its sym- bolic 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 nu- merical index) the default sink. Use the special name @NONE@ to unset the user defined default sink. This will make pulseaudio return to the default sink selection based on sink priority. set-sink-port SINK PORT Set the specified sink (identified by its symbolic name or nu- merical 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. Use the special name @NONE@ to unset the user defined default source. This will make pulseaudio return to the default source selection based on source priority. set-source-port SOURCE PORT Set the specified source (identified by its symbolic name or nu- merical 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 sym- bolic 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 per- centage (e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If the volume specification start with a + or - the volume adjust- ment will be relative to the current sink volume. A single vol- ume 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 sym- bolic 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 ad- justment 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 vol- ume value affects all channels; if multiple volume values are given their number has to match the sink input's number of chan- nels. 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 speci- fied 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/Documenta- tion/User/SupportedAudioFormats/ for possible encodings. send-message RECIPIENT MESSAGE MESSAGE_PARAMETERS Send a message to the specified recipient object. If applicable an additional string containing message parameters can be speci- fied. A string is returned as a response to the message.
