auctl - control various audio server parameters
auctl [-audio servername] [-q]
[command...]
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.
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.
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.
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.
