Connecting audio equipment

the sound input and output ports on the computer. If you have an internal
CD-ROM drive, you can also use your computer to play and record sound
from audio compact discs (CDs).

and output options, record an alert sound, or play audio CDs, see the “Sound”
topic of Macintosh Guide, available in the Guide (
h) menu.
