 *
 * 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
