Adjusting audio
Sound is an important part of the computer experience. Your computer has a digital audio controller built
into the system board. Some models also have a high-performance audio adapter installed in one of the PCI
card slots.
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.
