Adjusting the headphone
volume
You may be able to plug headphones into the
headphone jack on the CD-ROM drive (not available on
all systems) or into the Out jack on the sound card on
the back of the tower.
For headphones plugged into a
CD-ROM drive
On some IBM Aptiva PCs, a headphone jack and a
volume control are located on the front of the CD-ROM
drive.
Volume Control
Headphone Jack
When your headphones are plugged into the headphone
jack on the CD-ROM drive, they will pick up only the
sound coming from an ordinary audio CD in the
CD-ROM drive. The headphones will not pick up other
sounds generated from your computer or any external
device connected to the computer, such as a MIDI
(Musical Instrument Digital Interface) keyboard.
When your headphones are plugged into this jack, use
the volume control on the CD-ROM drive to adjust the
16 Chapter 2: Getting started with your Aptiva computer
volume of the headphones. This volume control adjusts
the volume of the headphones, but not the speakers. If
you want to turn the speaker volume down while using
the headphones, use the volume control on the speaker.
For headphones plugged into the
sound card
On all models of the IBM Aptiva PC, the headphones can
be plugged into the Out jack on the sound card on the
back of the tower. This is the same jack you plug your
speakers into. You must disconnect your speakers to use
this jack with your headphones.
If you plug your headphones into the jack on the sound
card, the headphones will pick up all sounds generated
from your computer and any external devices connected
to the computer, such as a MIDI keyboard. The
headphones will also pick up sound coming from a CD
in the CD-ROM drive. When using this jack, a few
sounds may not be audible through the headphones,
such as the beep that sounds when you turn on your
Eject
computer.
Busy Light
When your headphones are plugged into the jack on the
sound card, you must control the headphone volume
through the volume control in the multimedia software
on your computer. You cannot control the headphone
volume from the volume control on the CD-ROM drive
or from the volume control on the monitor.
