/*
 * ALSA driver for the Aureal Vortex family of soundprocessors.
 * Author: Manuel Jander (mjander@embedded.cl)
 *
 *   This driver is the result of the OpenVortex Project from Savannah
 * (savannah.nongnu.org/projects/openvortex). I would like to thank
 * the developers of OpenVortex, Jeff Muizelaar and Kester Maddock, from
 * whom i got plenty of help, and their codebase was invaluable.
 *   Thanks to the ALSA developers, they helped a lot working out
 * the ALSA part.
 *   Thanks also to Sourceforge for maintaining the old binary drivers,
 * and the forum, where developers could comunicate.
 *
 * Now at least i can play Legacy DOOM with MIDI music :-)
