/*
 * programming the msp34* sound processor family
 *
 * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
 *
 * what works and what doesn't:
 *
 *  AM-Mono
 *      Support for Hauppauge cards added (decoding handled by tuner) added by
 *      Frederic Crozat <fcrozat@mail.dotcom.fr>
 *
 *  FM-Mono
 *      should work. The stereo modes are backward compatible to FM-mono,
 *      therefore FM-Mono should be allways available.
 *
 *  FM-Stereo (B/G, used in germany)
 *      should work, with autodetect
 *
 *  FM-Stereo (satellite)
 *      should work, no autodetect (i.e. default is mono, but you can
 *      switch to stereo -- untested)
 *
 *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
 *      should work, with autodetect. Support for NICAM was added by
 *      Pekka Pietikainen <pp@netppl.fi>
 *
 *
 * TODO:
 *   - better SAT support
 *
 *
 * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)
 *         using soundcore instead of OSS
 *
 *
 * The FreeBSD modifications by Alexander Langer <alex@FreeBSD.org>
 * are in the public domain.  Please contact me (Alex) and not Gerd for
 * any problems you encounter under FreeBSD.
 * 
 * FreeBSD TODO: 
 * - mutex handling (currently not mp-safe)
 * - the various options here as loader tunables or compile time or whatever
 * - how does the new dolby flag work with the current dpl_* stuff?
 *   Maybe it's just enough to set the dolby flag to 1 and it works.
 *   As I don't have a dolby card myself, I can't test it, though.
