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