20 Controlling the volume on multimedia systems
Controlling the volume on multimedia systems
If you have a multimedia model of the IBM Aptiva
Personal Computer, you can control the volume in three
ways:
•
With the volume control on one of the speakers
•
With the volume controls in the multimedia software
that came with your system
•
With the volume control on the CD-ROM drive on
the front of the system unit (your system may not
have this volume control). This volume control is
used
solely to control headphone volume and has
no effect on the speakers.
The method you use to control the volume depends on
whether you are listening to sound through the speakers
or the headphones.
Adjusting the speaker volume
If you are listening to sound through the speakers, use
the volume control on the front of the speaker to adjust
the volume.
The volume control on the front of the speaker is
affected by the volume control setting in the multimedia
software that came with your computer. For example, if
you turn the volume on the speaker all the way up, and
no sound comes out of the speakers, the volume setting
in your multimedia software is too low.
The multimedia software volume controls are located in
the multimedia software group.
Adjusting the headphone
volume
You may be able to plug your headphones into the
headphone jack on the CD-ROM drive (not available on
all systems) or the
Out jack on the sound card on the
back of the computer’s system unit.
•
On some IBM Aptiva PCs, a headphone jack is
located on the CD-ROM drive on the front of the
computer’s system unit.
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.
