-/*
- * programming the msp34* sound processor family
- *
- * (c) 1997-2000 Gerd Knorr <kraxel@goldbach.in-berlin.de>
- *
- * what works and what doesn't:
- *
- * AM-Mono
- * Support for Hauppauge cards added (decoding handled by tuner) added by
- * Frederic Crozat <fcrozat@mail.dotcom.fr>
- *
- * FM-Mono
- * should work. The stereo modes are backward compatible to FM-mono,
- * therefore FM-Mono should be allways available.
- *
- * FM-Stereo (B/G, used in germany)
- * should work, with autodetect
- *
- * FM-Stereo (satellite)
- * should work, no autodetect (i.e. default is mono, but you can
- * switch to stereo -- untested)
- *
- * NICAM (B/G, L , used in UK, Scandinavia, Spain and France)
- * should work, with autodetect. Support for NICAM was added by
- * Pekka Pietikainen <pp@netppl.fi>
- *
- *
- * TODO:
- * - better SAT support
- *
- *
- * 980623 Thomas Sailer (sailer@ife.ee.ethz.ch)
- * using soundcore instead of OSS
- *
