   2  * programming the msp34* sound processor family
   3  *
   4  * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
   5  *
   6  * what works and what doesn't:
   7  *
   8  *  AM-Mono
   9  *      Support for Hauppauge cards added (decoding handled by tuner) added by
  10  *      Frederic Crozat <fcrozat@mail.dotcom.fr>
  11  *
  12  *  FM-Mono
  13  *      should work. The stereo modes are backward compatible to FM-mono,
  14  *      therefore FM-Mono should be allways available.
  15  *
  16  *  FM-Stereo (B/G, used in germany)
  17  *      should work, with autodetect
  18  *
  19  *  FM-Stereo (satellite)
  20  *      should work, no autodetect (i.e. default is mono, but you can
  21  *      switch to stereo -- untested)
  22  *
  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>
  26  *
  27  *
  28  * TODO:
  29  *   - better SAT support
  30  *
  31  *
  32  * 980623  Thomas Sailer (sailer@ife.ee.ethz.ch)
  33  *         using soundcore instead of OSS
