Show a quick help on the commands available.

Show all currently loaded modules with their arguments.

Show all currently registered cards

Show all currently registered sinks (resp. sources).

Show all currently active clients.

Show all currently active inputs to sinks a.k.a. playback streams (resp. outputs of sources a.k.a. recording streams).

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

A combination of all status commands described above (all three commands are synonyms).

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

Unload a module specified by its index in the module list as returned by list-modules.

Give information about a module specified by its name.

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).

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

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

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.

Change the profile of a card.

Change the profile of a sink (resp. source).

Suspend (i.e. disconnect from the underlying hardware) a sink (resp. source).

Suspend all sinks and sources.

Move sink input (resp. source output) to another sink (resp. source).

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 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 a sample cache entry to a sink.

Remove an entry from the sample cache.

Load an audio file to the sample cache.

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 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.

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

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.

Change the log level.

Show source code location in log messages.

Show timestamps in log messages.

Show backtrace in log messages.

Play an audio file to a sink.

Dump the daemon's current configuration in CLI commands.

Debug: Shows the current state of all volumes.

Debug: Show shared properties.

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

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

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.

Enable (resp. disable) extra verbosity.
