/*
  NOTES:
  - spdif nonaudio consumer mode does not work (at least with my
    Sony STR-DB830)
*/

/*
 * Changes:
 *
 *  2002.09.09	Takashi Iwai <tiwai@suse.de>
 *	split the code to several files.  each low-level routine
 *	is stored in the local file and called from registration
 *	function from card_info struct.
 *
 *  2002.11.26	James Stafford <jstafford@ampltd.com>
 *	Added support for VT1724 (Envy24HT)
 *	I have left out support for 176.4 and 192 KHz for the moment.
 *  I also haven't done anything with the internal S/PDIF transmitter or the MPU-401
 *
 *  2003.02.20  Taksahi Iwai <tiwai@suse.de>
 *	Split vt1724 part to an independent driver.
 *	The GPIO is accessed through the callback functions now.
 *
 * 2004.03.31 Doug McLain <nostar@comcast.net>
 *    Added support for Event Electronics EZ8 card to hoontech.c.
