Using audio features
Your computer comes with an integrated audio controller that supports Sound
Blaster applications and is compatible with the Microsoft Windows Sound
System. Some models also come with a single internal speaker and three audio
connectors. The audio controller provides you with the ability to record and
play sound and music and to enjoy sound with multimedia applications.
Optionally, you can connect two stereo speakers to the line out connector to
enjoy better sound quality.
Procedures for recording and playing back sound vary by operating system.
Refer to your operating system documentation for information and
instructions.
The audio connectors in your computer are 3.5 mm (1/8-in.) mini-jacks. A
description of the connectors follows. (For the location of the connectors, refer
to “Connecting computer cables” on page 7.)
Line/Headphone Out:
This jack is used to send audio signals from the computer to external
devices, such as stereo-powered speakers with built-in amplifiers,
headphones, multimedia keyboards, or the Audio Line-In jack on a
stereo system.
Note: The internal speaker in your computer is disabled when an
external speaker is connected to the headphone port on your
computer.
Audio Line In:
This jack is used to accept audio signals from external devices, such as
line output from a stereo or television system, or a musical
instrument, into the computer sound system.
Microphone:
This jack is used to connect a microphone to your computer when you
want to record voice or other sounds on the hard disk. This port can
also be used by speech-recognition software.
Note: If you experience interference or speaker feedback while
recording, try reducing the microphone recording volume
(gain).
Joystick/MIDI (some models only):
This port is used to connect a joystick for playing games or a MIDI
device to interface with digital musical and sound production
equipment.
