+/*
+ * 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

- *
- * 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
