  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 :-)
