3 * ALSA driver for the Aureal Vortex family of soundprocessors.
4 * Author: Manuel Jander (mjander@embedded.cl)
5 *
6 * This driver is the result of the OpenVortex Project from Savannah
7 * (savannah.nongnu.org/projects/openvortex). I would like to thank
8 * the developers of OpenVortex, Jeff Muizelaar and Kester Maddock, from
9 * whom i got plenty of help, and their codebase was invaluable.
10 * Thanks to the ALSA developers, they helped a lot working out
11 * the ALSA part.
12 * Thanks also to Sourceforge for maintaining the old binary drivers,
13 * and the forum, where developers could comunicate.
14 *
15 * Now at least i can play Legacy DOOM with MIDI music :-)
