This is Debian GNU/Linux's prepackaged version of the xmix utility. This package provides an X11 based graphical interface to the sound driver mixer. This package was put together by me, Owen Dunn , from the original sources, which I obtained from: rzbsdi01.uni-trier.de:/pub/unix/audio/xmix/xmix-2.1.tar.gz The changes were very minimal - merely adding support for the Debian package maintenance scheme, by adding various debian/* files. xmix is Copyright (C) 1992 Steve Haehnichen.
