2 *
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
