1. Aumix is a tty-based, interactive method of controlling a sound card mixer. It lets you adjust the input levels from the CD, microphone, and board synthesizers, as well as the output volume. Aumix can adjust audio mixers from the command line, from a script, or interactively at the console or terminal with an ncurses-based interface. The aumix-X11 package provides a GTK+ interface for using aumix with the X Window System. From Redhat 8.0 RPM

2. Simple text-based mixer control program aumix is a small, easy-to-use program to control the mixer of your sound card. It runs in text mode using the ncurses library, or from the command line (non-interactively). It can read default settings from a file. A wrapper script xaumix is provided that finds and invokes xterm or a replacement. This is primarily for creating the best sized terminal window. If you want a true graphical interface, install aumix-gtk instead. That has the same functionality as this one in addition to offering a nice X11 GUI. The old companion package aumix-alsa, which did take advantage of the extra facilities in the ALSA sound driver, is no longer available. This package should work fine with the ALSA driver. From Debian 3.0r0 APT

3. This is a program for adjusting audio mixers from the command line or scripts, or interactively at the console or a terminal with a full-screen, ncurses-based interface or a GTK-based X interface. From Mandrake 9.0 RPM
