Using audio features
Your computer has an integrated audio controller that supports Sound
Blaster applications and is compatible with the Microsoft Windows Sound
System. Your computer also has a single internal speaker and three audio
connectors. Using the audio controller, you can record and play back
sound and music and enjoy sound with multimedia applications.
Optionally, you can connect two stereo speakers to the line-out connector to
enjoy better sound with multimedia applications.
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,
see “Connecting cables” on page 13.)
Line out/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 connector on your computer.
Audio line in
This jack is used to accept audio signals from external devices, such as line
output from a stereo, television, or musical instrument, into the computer
sound system.
Microphone in
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 jack 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).
Procedures for recording and playing back sound vary by operating system.
See your operating system documentation for information and instructions.
