okay bestie, buckle up, we're reading the smix(1) page together and it's genuinely so useful. smix is a Simple LINUX Mixer Program and it's about to become your new fave 🎀

✨ NAME ✨

smix — A Simple LINUX Mixer Program

🌸 SYNOPSIS 🌸

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

🦋 DESCRIPTION 🦋

so smix is a simple mixer program that either reports or controls the Mixer settings of /dev/mixer — or, like, whatever specific mixer device file you point it at with the -m file option — straight from the command line parameter(s). no GUI, no drama, just vibes 💅

The commands are detailed below, and the capitals show 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 mixer's actual range, hence the set volume may be slightly different. iykyk 🫶

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. literally the main character default behaviour 👑
  • 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 the device doesn't support stereo settings then the max of L,R is used. The word off can be used instead of 0 and full can be used instead of 100. so iconic of it ✨
  • ALL N or L,R — sets all mixer devices to the specified volume setting (see above).
  • INput dev — set the DSP input to be dev or NOne to turn inputs off
  • Verbose — makes the program output the settings after doing the commands

💅 OPTIONS 💅

  • -h — show usage summary, which also lists the mixer devices and the possible input devices. the little map you need fr fr 🗺️
  • -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. no cap, it has to be valid or it's not happening 🙈
  • -s — causes smix to output mixer settings etc in a form that can be read by smix to cause the same settings to be 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. it's giving time-travel for your mixer settings ⏪💖

Use - as a filename to indicate standard input.

🎀 EXAMPLES 🎀

  • 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 be typed and executed interactively and control is retained of the mixer while smix is running. interactive slay ✨
  • 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 output.

🌈 OPTIONAL CONFIGURATION FILES 🌈

Three possible configuration files can be used: a LOCAL config file (usually in current directory), a HOME config file in the 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:

  • ./.siggen.conf — is the LOCAL config file.
  • $HOME/.siggen.conf — is the HOME config file.
  • /etc/siggen.conf — 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. no pressure, they're just there if you want them 🧚

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 directory. honestly? a whole hierarchy of vibes 👑

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.

  • MIXERFILE — allows the name of the mixer device file to be changed from /dev/mixer
  • VERBOSE — sets whether or not to run in verbose mode.
