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 allways 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.
