NAME

       auctl - control various audio server parameters

SYNOPSYS

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

DESCRIPTION

       The  auctl  program  can  be  used to control various audio server parameters.  It is typically used when
       connecting up new devices, or to set user preferences.  If no command is specified on the program command
       line,  auctl reads commands from the standard output.  If the standard input and standard output are both
       attached to a terminal, an interactive prompt is provided.

OPTIONS

       The following options may be used with auctl:

       -audio servername
               This option specifies the Network Audio System server on which the files should be played.

       -q      This option indicates that no prompt should be given when  reading  commands  from  the  standard
               input.

COMMANDS

       The following commands may be used with auctl:

       help    This command prints a list of the commands that may be given.

       set device id gain [=,+,-] percent
               With  =, this command sets the gain on the device specified by id to the indicated percentage, or
               alters it by the given number of percentage points if + or - is used.  If the  id  is  a  decimal
               number  n, the nth device returned by the server (see auinfo) is used.  Otherwise, id should be a
               hexidecimal number specifying the resource identifier of the desired device.

       set device id linemode = low
               This command sets the linemode of the device specified by id to the lower setting appropriate for
               microphones.

       set device id linemode = hi
               This  command  sets  the linemode of the device specified by id to the higher setting appropriate
               for CD players.

       list device id gain
               This command lists the gain of the specified device in the form needed to set it.

       list device id linemode
               This command lists the line mode of the specified device in the form needed to set it.

       list device id
               This command lists the gain and line mode of the specified device.

       quit, exit, or ^D
               Either of these commands or an end of file causes the program to exit.

ENVIRONMENT VARIABLES

       The following environment variables are used by auctl:

       AUDIOSERVER
               This specifies the name of default audio server to contact if no name is explicitly given on  the
               command line.

       DISPLAY This  specifies  the  name  of  an  X Window System display that should be assumed to also have a
               corresponding Network Audio System server.
