2 * programming the msp34* sound processor family
4 * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
6 * what works and what doesn't:
9 * Support for Hauppauge cards added (decoding handled by tuner) added by
10 * Frederic Crozat <fcrozat@mail.dotcom.fr>
13 * should work. The stereo modes are backward compatible to FM-mono,
14 * therefore FM-Mono should be allways available.
16 * FM-Stereo (B/G, used in germany)
17 * should work, with autodetect
19 * FM-Stereo (satellite)
20 * should work, no autodetect (i.e. default is mono, but you can
21 * switch to stereo -- untested)
23 * NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
24 * should work, with autodetect. Support for NICAM was added by
25 * Pekka Pietikainen <pp@netppl.fi>
29 * - better SAT support
32 * 980623 Thomas Sailer (sailer@ife.ee.ethz.ch)
33 * using soundcore instead of OSS
