3  * Linux multisound pinnacle/fiji driver for ALSA.
4  *
5  * 2002/06/30 Karsten Wiese:
6  *	for now this is only used to build a pinnacle / fiji driver.
7  *	the OSS parent of this code is designed to also support
8  *	the multisound classic via the file msnd_classic.c.
9  *	to make it easier for some brave heart to implemt classic
10  *	support in alsa, i left all the MSND_CLASSIC tokens in this file.
11  *	but for now this untested & undone.
12  *
13  *
14  * ripped from linux kernel 2.4.18 by Karsten Wiese.
15  *
16  * the following is a copy of the 2.4.18 OSS FREE file-heading comment:
17  *
18  * Turtle Beach MultiSound Sound Card Driver for Linux
19  * msnd_pinnacle.c / msnd_classic.c
20  *
21  * -- If MSND_CLASSIC is defined:
22  *
23  *     -> driver for Turtle Beach Classic/Monterey/Tahiti
24  *
25  * -- Else
26  *
27  *     -> driver for Turtle Beach Pinnacle/Fiji
