+/*********************************************************************
+ *
+ * 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
