 *

 * Linux multisound pinnacle/fiji driver for ALSA.

 *

 * 2002/06/30 Karsten Wiese:

 *  for now this is only used to build a pinnacle / fiji driver.

 *  the OSS parent of this code is designed to also support

 *  the multisound classic via the file msnd_classic.c.

 *  to make it easier for some brave heart to implemt classic

 *  support in alsa, i left all the MSND_CLASSIC tokens in this file.

 *  but for now this untested & undone.

 *

 *

 * ripped from linux kernel 2.4.18 by Karsten Wiese.

 *

 * the following is a copy of the 2.4.18 OSS FREE file-heading comment:

 *

 * Turtle Beach MultiSound Sound Card Driver for Linux

 * msnd_pinnacle.c / msnd_classic.c

 *

 * -- If MSND_CLASSIC is defined:

 *

 *     -> driver for Turtle Beach Classic/Monterey/Tahiti

 *

 * -- Else

 *

 *     -> driver for Turtle Beach Pinnacle/Fiji
