Graphical audio mixer
alsamixergui is an FLTK based mixer program for use with the ALSA soundcard drivers. It supports multiple soundcards with multiple devices.
alsamixergui is a frontend for alsamixer, written directly on top of the alsamixer source, leaving the original source intact, only adding a couple of ifdefs, and some calls to the gui part. It provides exactly the same functionality, but with a graphical user interface.
