46              specified, all info is listed. If short is given, output is in a
47              tabular format, for easy parsing by scripts.
48
49       exit   Asks the PulseAudio server to terminate.
50
51       upload-sample FILENAME [NAME]
52              Upload  a  sound  from  the specified audio file into the sample
53              cache. The file types supported are those understood by  libsnd‐
54              file.  The  sample  in  the cache is named after the audio file,
55              unless the name is explicitly specified.
56
57       play-sample NAME [SINK]
58              Play the specified sample from the sample cache. It is played on
59              the  default  sink,  unless  the  symbolic name or the numerical
60              index of the sink to play it on is specified.
61
62       remove-sample NAME
63              Remove the specified sample from the sample cache.
64
65       load-module NAME [ARGUMENTS ...]
66              Load the specified module with the specified arguments into  the
67              running  sound  server.  Prints  the numeric index of the module
68              just loaded to STDOUT. You can  use  it  to  unload  the  module
69              later.
70
71       unload-module ID|NAME
72              Unload  the  module instance identified by the specified numeric
73              index or unload all modules by the specified name.
74
75       move-sink-input ID SINK
76              Move the specified playback stream (identified by its  numerical
77              index) to the specified sink (identified by its symbolic name or
78              numerical index).
79
80       move-source-output ID SOURCE
81              Move the specified recording stream (identified by its numerical
82              index)  to the specified source (identified by its symbolic name
83              or numerical index).
84
85       suspend-sink SINK 1|0
86              Suspend or resume the specified sink  (which  may  be  specified
87              either by its symbolic name, or by its numeric index), depending
88              whether 1 (suspend) or 0 (resume) is passed  as  last  argument.
89              Suspending a sink will pause all playback. Depending on the mod‐
90              ule implementing the sink this might have the  effect  that  the
91              underlying  device  is  closed,  making  it  available for other
92              applications to use. The exact behaviour depends on the module.
93
94       suspend-source SOURCE 1|0
95              Suspend or resume the specified source (which may  be  specified
96              either by its symbolic name, or by its numeric index), depending
97              whether 1 (suspend) or 0 (resume) is passed  as  last  argument.
98              Suspending  a  source will pause all capturing. Depending on the
99              module implementing the source this might have the  effect  that
100              the  underlying  device is closed, making it available for other
101              applications to use. The exact behaviour depends on the module.
102
103       set-card-profile CARD PROFILE
104              Set the specified card  (identified  by  its  symbolic  name  or
105              numerical  index)  to  the  specified profile (identified by its
106              symbolic name).
107
108       set-default-sink SINK
109              Make the specified sink (identified by its  symbolic  name)  the
110              default sink.
111
112       set-sink-port SINK PORT
113              Set  the  specified  sink  (identified  by  its symbolic name or
114              numerical index) to the specified port (identified by  its  sym‐
115              bolic name).
116
117       set-default-source SOURCE
118              Make  the specified source (identified by its symbolic name) the
119              default source.
120
121       set-source-port SOURCE PORT
122              Set the specified source (identified by  its  symbolic  name  or
123              numerical  index)  to the specified port (identified by its sym‐
124              bolic name).
125
126       set-port-latency-offset CARD PORT OFFSET
127              Set a latency offset to a specified port (identified by its sym‐
128              bolic  name)  that belongs to a card (identified by its symbolic
129              name or numerical index). OFFSET is a  number  which  represents
130              the latency offset in microseconds
131
132       set-sink-volume SINK VOLUME [VOLUME ...]
133              Set the volume of the specified sink (identified by its symbolic
134              name or numerical index). VOLUME can be specified as an  integer
135              (e.g.  2000,  16384),  a linear factor (e.g. 0.4, 1.100), a per‐
136              centage (e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB). If
137              the  volume specification start with a + or - the volume adjust‐
138              ment will be relative to the current sink volume. A single  vol‐
139              ume  value  affects  all channels; if multiple volume values are
140              given their number has to match the sink's number of channels.
141
142       set-source-volume SOURCE VOLUME [VOLUME ...]
143              Set the volume of the specified source (identified by  its  sym‐
144              bolic  name  or  numerical index). VOLUME can be specified as an
145              integer (e.g. 2000, 16384), a linear factor (e.g. 0.4, 1.100), a
146              percentage (e.g. 10%, 100%) or a decibel value (e.g. 0dB, 20dB).
147              If the volume specification start with  a  +  or  -  the  volume
148              adjustment will be relative to the current source volume. A sin‐
149              gle volume value affects all channels; if multiple volume values
150              are given their number has to match the source's number of chan‐
151              nels.
152
153       set-sink-input-volume INPUT VOLUME [VOLUME ...]
154              Set the volume of the specified sink input  (identified  by  its
155              numerical  index).  VOLUME  can be specified as an integer (e.g.
156              2000, 16384), a linear factor (e.g. 0.4,  1.100),  a  percentage
157              (e.g.  10%,  100%)  or  a decibel value (e.g. 0dB, 20dB). If the
158              volume specification start with a + or - the  volume  adjustment
159              will be relative to the current sink input volume. A single vol‐
160              ume value affects all channels; if multiple  volume  values  are
161              given their number has to match the sink input's number of chan‐
162              nels.
163
164       set-source-output-volume OUTPUT VOLUME [VOLUME ...]
165              Set the volume of the specified source output (identified by its
166              numerical  index).  VOLUME  can be specified as an integer (e.g.
167              2000, 16384), a linear factor (e.g. 0.4,  1.100),  a  percentage
168              (e.g.  10%,  100%)  or  a decibel value (e.g. 0dB, 20dB). If the
169              volume specification start with a + or - the  volume  adjustment
170              will  be  relative to the current source output volume. A single
171              volume value affects all channels; if multiple volume values are
172              given  their  number  has to match the source output's number of
173              channels.

192              Set the supported formats of the specified sink  (identified  by
193              its numerical index) if supported by the sink. FORMATS is speci‐
194              fied as a semi-colon (;) separated list of formats in  the  form
195              'encoding[, key1=value1, key2=value2, ...]' (for example, AC3 at
196              32000, 44100 and 48000 Hz would be specified  as  'ac3-iec61937,
197              format.rate = "[ 32000, 44100, 48000 ]"').
