I have two CD-ROM drives connected together using the grey ribbon cable to the Secondary IDE. I want to be sure that when I finally finish the computer that sound from both CD-ROM's will work. I've connected the audio cable from the first CD-ROM onto the CD Audio to the motherboard. I only have one CD audio to the motherboard however, the motherboard also has an AUX in to the motherboard that uses the same 4 pin setup as the CD audio in. Should I plug the other CD-ROM audio connector into the additional AUX 4-pin input, or will the audio on the second CD-ROM work... maybe because the two CD-ROM's are connected together by the ribbon cable?
