You don't give enough information to answer yuor question.  However the
basic answer is RTFM.

Get the manual for the particular brand of CD-ROM drive you have and
look for the SCSI commands that cause it to play an audio CD through
the headphone jack (or line-out jacks) on the CD-ROM drive.

If you want to read audio data from an audio CD into your system you are
out of luck unless your system is a Silicon Graphics IRIS Indigo or
Personal IRIS 4D/35.  SGI ships a specially modified version of the
Toshiba 3301B CD-ROM drive that can read audio CD's and transfer the
data across the SCSI bus.  Currently this is the only CD-ROM drive in
the world that can do this.  SGI also ships a library,libcdaudio, that
makes it easy to take advantage of the special features and a CD player
program, cdman, that plays CD's through the Indigo's audio hardware.

If you have an Indigo, the answer is still RTFM.
