Gom is a command line mixer utility with optional built-in ncurses interactive interface.

Its main feature is an exhaustive command line interface that makes it ideal for scripting (e.g. for audio recording, running at user and/or system login time, setting/restoring of settings, etc).

It supports OSS only, so if you want to use it with ALSA, you will need its OSS-compatible modules. If you want to use all possible features of ALSA however, you would need to use a mixer program dedicated for ALSA.
