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