MightyGem,
It would be nice if you actually gave us details on the computer and at the very minimum which Operating System you are running. In the old days when everyone has Win95 or Win98, you needed to have the Analog Audio Cable going from the CD-ROM to the Sound Card in order for audio to be played. With WinXP the audio goes though the IDE Cable, as mentioned above.
But if you do not give us any details, we cannot solve the problem for you. All we can tell you is your computer is not functioning properly.
Take Care,
Richard
