AUCTL(1)                 USER COMMANDS                   AUCTL(1)



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  stan-
     dard  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 NCDaudio 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
             This command sets the gain on the  device  specified
             by  id  to the indicated percentage.  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  speci-
             fied  by  id  to  the  lower setting appropriate for
             microphones.

     set device id linemode = hi
             This command sets the linemode of the device  speci-
             fied  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.

AUCTL(1)                 USER COMMANDS                   AUCTL(1)



     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 com-
             mand line.

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