29/*
30 * programming the msp34* sound processor family
31 *
32 * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
33 *
34 * what works and what doesn't:
35 *
36 *  AM-Mono
37 *      Support for Hauppauge cards added (decoding handled by tuner) added by
38 *      Frederic Crozat <fcrozat@mail.dotcom.fr>
39 *
40 *  FM-Mono
41 *      should work. The stereo modes are backward compatible to FM-mono,
42 *      therefore FM-Mono should be always available.
43 *
44 *  FM-Stereo (B/G, used in germany)
45 *      should work, with autodetect
46 *
47 *  FM-Stereo (satellite)
48 *      should work, no autodetect (i.e. default is mono, but you can
49 *      switch to stereo -- untested)
50 *
51 *  NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
52 *      should work, with autodetect. Support for NICAM was added by
53 *      Pekka Pietikainen <pp@netppl.fi>
54 *
55 *
56 * TODO:
57 *   - better SAT support
58 *
59 *
60 * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)
61 *         using soundcore instead of OSS
62 *
63 *
64 * The FreeBSD modifications by Alexander Langer <alex@FreeBSD.org>
65 * are in the public domain.  Please contact me (Alex) and not Gerd for
66 * any problems you encounter under FreeBSD.
67 *
68 * FreeBSD TODO:
69 * - mutex handling (currently not mp-safe)
70 * - the various options here as loader tunables or compile time or whatever
71 * - how does the new dolby flag work with the current dpl_* stuff?
72 *   Maybe it's just enough to set the dolby flag to 1 and it works.
73 *   As I don't have a dolby card myself, I can't test it, though.
