I have recently acquired a brand new Mitsumi CD-ROM drive, with which I am thrilled. It is suberb with my Photo CD images and was simple to install. . .however. . I also have a Soundblaster II card. Is there any way please of getting all my CDs (other than Photo CDs of course!) to use the Soundblaster card, since there is no obvious direct link between the two of them. Thank you in anticipation of a reply Paul Climance – Liverpool U.K.

Paul I have a Mitsumi LU005 CD-Rom Drive (internal). I also have a Soundblaster Pro in the PC. The connection between the two is via an internal cable which has 4 wires. It plugs into the back of the CD rom drive and into a plug on the SoundBlaster called CD-in. This plug is shown in the diagram in the SoundBlaster Getting Started manual on page 6. I used the standard cable supplied with the Drive. However, you do have to rewire the cable at the SoundBlaster end. The wiring scheme for the CD-ROM drive plug is Pin 1: Right Channel; Pin 2: Ground; Pin 3: Left Channel; and Pin 4: Ground. You can see this in the Mitsumi manual on page 12. The wiring scheme for the SoundBlaster plug is Pin 1: Ground; Pin 2: Left Channel; Pin 3: Ground; Pin 4: Right Channel. This wiring scheme is not listed in the SoundBlaster Manual! I got it by calling Creative Technology in Milpitas California. If you study the two schemes you can see they are mirror images of each other – so the rewiring is quite simple: you just reverse the wires at the SoundBlaster end in a mirror image pattern. This works fine for the SoundBlaster Pro. Maybe the process is similar for the SoundBlaster 2? Even though the two cards are different I… hope this helps. Jim C

Jim Thanks very much for the info. . unfortunately, my Soundblaster card has NO CD-in port. It has only a Line-In around the back so it's back to the drwaing board! Thanks again for taking the time to do my thinking!!??!! Paul Climance

The SB Pro's CD-in port is not on the back of the card. It is internal. I'm not sure which model you have, but if you have the SB Pro check your documentation for that port. -cjh
