aumix-gtk binary package in Ubuntu Focal i386

 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, and it
 can also automatically save and restore the mixer settings at shutdown and
 boot.
 .
 Additionally this version can be run as a GTK+ app, i.e. with a graphical
 interface. It can also still run in text-only mode, though.
