; Change History (most recent first):
;
; <SM5> 11/12/93 ged Added new sound primitive vectors to synch with Horror/Kaos as
; much as possible (see in-line comments).
; <SM4> 12/4/92 SWC Added new sound vector table entry for InitSoundHW.
; <SM3> 6/4/92 KW (NJV,H9) Added sndPlayThruBit equate for DFAC's Playthru enable
; bit.
; (NJV,H8) Added sndSonoraReverseDFAC value for use in
; SonoraDriver.a
; <SM2> 5/17/92 kc Roll in Horror Changes. Comments follow:
; <H7> 4/3/92 SWC Added ADB/DebugUtil equates.
; <H6> 3/25/92 NJV Changed sndSonoraDFAC again to account for new SonoraDFACInit
; routine
; <H5> 3/24/92 NJV Changed sndSonoraDFAC to disable playthru
; <H4> 3/12/92 NJV Added sndSonoraDFAC for Sonora-based machines.
; <H3> 10/15/91 SWC Added table entry for initializing clock/PRAM hardware.
; <H2> 10/15/91 SWC Added clock/PRAM equates.
; <T5> 5/31/91 djw Update DBLite DFAC initialization value
; <T4> 5/10/91 djw Fix ByPass equate bug, add user AGC field to SoundIOHeader, roll
; in DBLite equates.
; <T3> 3/18/91 djw Add routine specific definitions. Change all DFAC specific
; equates from Egret to DFAC order.
; <T2> 2/18/91 djw Add mask value for leaving agc enabled on Eclipse.
; <6> 1/22/92 RB Updated the value of sndEclipseDFAC, sndSpikeDFAC and
; sndDBLiteDFAC to the values found in Terror.
; <5> 10/28/91 SAM/KSM Rolled in Regatta changes.
;
; Regatta Change History:
;
; <1> 4/30/91 djw Fix ByPass equate bug, add user AGC field to SoundIOHeader,
; roll in DBLite equates.
; 7.0 Change History:
;
; <4> 8/22/91 JSM Clean up header.
; <3> 8/7/91 KIP Add macro to test for existance of one of the sound primitive
; vectors.
; <2> 6/11/91 gbm Take out conditional for Regatta
; <1> 4/3/91 KIP first checked in
; <3> 3/18/91 djw Add routine specific definitions. Change all DFAC specific
; equates from Egret to DFAC order.
; <2> 2/18/91 djw Add mask value for leaving agc enabled on Eclipse.
; <1> 2/15/91 djw first checked in
