- * Programming the mspx4xx sound processor family
- *
- * (c) 1997-2001 Gerd Knorr <kraxel@bytesex.org>
- *
- * 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
