About your computer audio

If a factory-installed, high-performance audio adapter is installed in your computer, the system-board audio connectors on the rear of the computer are typically disabled; use the connectors provided on the audio adapter.

Each audio solution provides at least three audio connectors: audio line-in connector, audio line-out connector, and Microphone connector. On some models, a fourth connector is provided for the attachment of unpowered stereo speakers (speakers that do not require an ac power source). The audio adapter provides you with the ability to record and play back sound and music, as well as to enjoy sound with multimedia applications and work with speech-recognition software.

Optionally, you can connect a set of powered stereo speakers to the audio line-out connector to enjoy better sound with multimedia applications.
