* - SMP support ( spin[un]lock* revision )
- * - speaker mixer support
+ * - speaker mixer support
* Mon Aug 13 2001
* - optimizations and cleanups
+ *
* 03/01/2003 - open_mode fixes from Georg Acher <acher@in.tum.de>
+ * Simon Braunschmidt <brasimon@web.de>
+ * Sat Jan 31 2004
+ * - provide support for opl3 FM by releasing IO range after initialization
+ *
+ * ChenLi Tien <cltien@cmedia.com.tw>
+ * Mar 9 2004
+ * - Fix S/PDIF out if spdif_loop enabled
+ * - Load opl3 driver if enabled (fmio in proper range)
+ * - Load mpu401 if enabled (mpuio in proper range)
+ * Apr 5 2004
+ * - Fix DUAL_DAC dma synchronization bug
+ * - Check exist FM/MPU401 I/O before activate.
+ * - Add AFTM_S16_BE format support, so MPlayer/Xine can play AC3/mutlichannel
+ * on Mac
+ * - Change to support kernel 2.6 so only small patch needed
+ * - All parameters default to 0
+ * - Add spdif_out to send PCM through S/PDIF out jack
+ * - Add hw_copy to get 4-spaker output for general PCM/analog output
*
+ * Stefan Thater <stefan.thaeter@gmx.de>
+ * Apr 5 2004
+ * - Fix mute single channel for CD/Line-in/AUX-in
