NAME

6       auctl - control various audio server parameters
7

SYNOPSYS

9       auctl [-audio servername] [-q] [command...]
10

DESCRIPTION

12       The  auctl  program can be used to control various audio server parame‐
13       ters.  It is typically used when connecting up new devices, or  to  set
14       user  preferences.   If  no command is specified on the program command
15       line, auctl reads commands from the standard output.  If  the  standard
16       input  and standard output are both attached to a terminal, an interac‐
17       tive prompt is provided.
18

OPTIONS

20       The following options may be used with auctl:
21
22       -audio servername
23               This option specifies the Network Audio System server on  which
24               the files should be played.
25
26       -q      This option indicates that no prompt should be given when read‐
27               ing commands from the standard input.
28

COMMANDS

30       The following commands may be used with auctl:
31
32       help    This command prints a list of the commands that may be given.
33
34       set device id gain [=,+,-] percent
35               With =, this command sets the gain on the device  specified  by
36               id  to the indicated percentage, or alters it by the given num‐
37               ber of percentage points if + or - is used.  If  the  id  is  a
38               decimal  number  n,  the nth device returned by the server (see
39               auinfo) is used.  Otherwise, id should be a hexidecimal  number
40               specifying the resource identifier of the desired device.
41
42       set device id linemode = low
43               This command sets the linemode of the device specified by id to
44               the lower setting appropriate for microphones.
45
46       set device id linemode = hi
47               This command sets the linemode of the device specified by id to
48               the higher setting appropriate for CD players.
49
50       list device id gain
51               This command lists the gain of the specified device in the form
52               needed to set it.
53
54       list device id linemode
55               This command lists the line mode of the specified device in the
56               form needed to set it.
57
58       list device id
59               This  command lists the gain and line mode of the specified de‐
60               vice.
61
62       quit, exit, or ^D
63               Either of these commands or an end of file causes  the  program
64               to exit.
65

70               This  specifies  the name of default audio server to contact if
71               no name is explicitly given on the command line.
72
73       DISPLAY This specifies the name of an  X  Window  System  display  that
