Stephen, the pinout for the CD in connector on the SBP is as follows:
1=Ground; 2=CD Left Channel; 3=Ground; 4=CD Right Channel;
where pin 1 (marked as such on my board) is the left-most pin on the 4-pin
CD audio connector when looking at the board with the back plate to the
right.
I just connected my SBP internally to my NEC CDR-84, which is an internal
drive with a three-pin audio out connector, using the 3-wire cable Creative
Labs sells for audio connections between the SBP and their proprietary
CD-ROM drive. Note that Creative Lab's cable has only 3 wires. The SBP end
plugs onto pins pins 2, 3 and 4 on the board.
The setup works perfectly and has two advantages over cabling from the
audio out mini jack on the front of the drive to the line in jack on the
SBP. You get rid of the cable jutting out from the front of the system. And
the SBP mixer software that comes with the board has seperate controls for
line and CD-ROM audio, so you can independently set the input levels of the
CD-ROM and another source.
