       smix - A Simple LINUX Mixer Program


       smix [-v] [-h] [-o file] [-i file] [-m file] [-s] [command(s)]


       smix  ,  a  simple mixer program that reports or controls the Mixer settings of /dev/mixer
       (or the specific mixer device file specified by the "-m file"  option)  from  the  command
       line parameter(s).

       The  commands are detailed below, capitals showing the minimum abbreviation allowed. Upper
       or lower case can be used on the command line. All Volume settings are in range  0-100  (0
       min,  100  max),  but these are scaled to the mixers actual range, hence set volume may be
       slightly different.

       To see what devices/channels the mixer is configured with and to get  a  command  summary,
       use smix -h

       SHow or ALL
              outputs  the  settings  of  the  mixer.  This  is  the  default, if no command line
              parameters are given

       dev    outputs the current settings for the mixer device named "dev"

       dev N or L,R
              sets mixer device 'dev' to volume N, or to separate left and  right  stereo  volume
              L,R If device doesn't support stereo settings then max of L,R is used. The word off
              can be used instead of 0 and full can be used instead of 100.

       ALL N or L,R
              sets all mixer devices to specified volume setting (see above).

       INput dev
              set the DSP input to be 'dev' or 'NOne' to turn inputs off

              makes the program output the settings after doing the commands


       -h     show usage summary, which also lists the  mixer  devices  and  the  possible  input

       -v     be verbose - outputs the results of commands. Same as Verbose above

       -i file
              read commands from file

       -o file
              divert standard output to file.

       -m file
              use  file  instead  of  the  default  /dev/mixer . The file has to be a valid mixer
              device type.

       -s     causes smix to output mixer settings etc in a form that can  be  read  by  smix  to
              cause  the  same settings to set. This can be used to record the settings of all or
              part of the mixer into a file, change the settings, then  get  smix  to  reset  the
              original settings by giving the file as an input file, see examples below.

       Use '-' as a filename to indicate standard input.


       smix   Displays the current mixer devices and their current settings.

       smix -m /dev/mixer1
              Displays the devices and their current settings for /dev/mixer1

       smix input line1 line1 60 mic 0 show
              sets  input  to  line1,  line1 volume to 60 and mic volume to 0 (off) and shows the
              total resultant mixer settings.

       smix line1 60,0 show
              sets left line1 input to volume 60 and right line1 input to 0 (off) and  shows  the
              resultant output.

       smix -i /etc/mixer.default
              set the mixer settings from smix commands in /etc/mixer.default .

       smix -i -
              take  mixer  commands from stdin, with output to stdout. If stdin and stdout is the
              keyboard and display, then mixer commands can by typed and  executed  interactively
              and control is retained of the mixer while smix is running.

       smix -s -o mixer.conf
              record  the current settings of the default mixer in file mixer.conf in a form that
              can be fed back in to smix.

       smix -i mixer.conf -o /dev/null
              take the file saved, as above, and reset the  mixer  settings,  without  doing  any


       Three  possible  configuration  files can be used: a LOCAL config file (usually in current
       directory), a HOME config file in user's $HOME directory and a GLOBAL config file.

       All the siggen suite of programs are compiled with the names of the config files built in.
       By default the configuration files are:

              is the LOCAL config file.

              is the HOME config file.

              is the GLOBAL config file.

       smix -h
              will indicate which config files will be searched for.

       The  config files do not have to exist. If they exist and are readable by the program they
       are used, otherwise they are simply ignored.

       The config files are always searched for configuration values in the  order  LOCAL,  HOME,
       GLOBAL.  This  allows  a  scheme  where  the sysadmin sets up default config values in the
       GLOBAL config file, but allows a user to set some or all different  values  in  their  own
       HOME  config  file,  and  to  set  yet  more  specific  values  when run from a particular

       If no configuration files exist, the program provides builtin default  values,  and  these
       values can be set by appropriate command line options and flags.

       See siggen.conf(5) for details of the configuration files.

       smix currently looks for configuration values MIXERFILE, VERBOSE.

              allows the name of the mixer device file to be changed from /dev/mixer

              sets whether or not to run in verbose mode.



       All the other mixer programs that float around the internet.
