/*
* programming the msp34* 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
*
*
* The FreeBSD modifications by Alexander Langer <alex@FreeBSD.org>
* are in the public domain. Please contact me (Alex) and not Gerd for
* any problems you encounter under FreeBSD.
*
* FreeBSD TODO:
* - mutex handling (currently not mp-safe)
* - the various options here as loader tunables or compile time or whatever
* - how does the new dolby flag work with the current dpl_* stuff?
* Maybe it's just enough to set the dolby flag to 1 and it works.
* As I don't have a dolby card myself, I can't test it, though.
