 * 
 *    Rev 1.5   24 Sep 1992 08:59:06   DCODY
 * changed MVGetHardware to mvGetHardware
 * 
 *    Rev 1.4   28 Jul 1992 15:52:20   DCODY
 * added TurnItOff, TurnItOn to get rid of feedback during recordings.
 * 
 *    Rev 1.3   20 Jul 1992 11:39:06   DCODY
 * call to mvGetHWVersion now uses active I/O address detection.
 * 
 *    Rev 1.2   13 Jul 1992 19:05:04   DCODY
 * removed initmvsound call. changed pcmstate to add 8 bit pcm parm.
