It may also be cleared if you perform an installation that requires a restart.

Mouse

The Power Mac G5 computer comes with an Apple Mouse. The mouse case is made of polycarbonate plastic.

The Apple Mouse uses optical tracking in place of the traditional rolling ball. It works on almost any surface,

though nonreflective, opaque surfaces without repetitive patterns work best.

Audio

The Power Mac G5 computer supports a sound system with both digital and analog audio. The new digital

capability features Sony/Phillips Digital Interface (S/PDIF) input and output using optical connectors. S/PDIF

technology results in a clean audio signal with no added noise to or from an external audio device.

Under the control of the system software, the sound circuitry digitally creates and records sounds. The Power

Mac G5 computer can receive input only from either the analog input or the digital input. However, it can

output simultaneously to digital and analog devices: the internal speaker, the headphone jack, the audio output

jack, and the optical digital output connector.

By default, when components are plugged into the headphone jack or the rear line-out, the sound system

mutes the internal speaker.

The headphones, rear line-out jack, and optical digital output are only muted when selected in the System

Preferences. Muting and sound options are set in System Preferences:Sound:Output.

The analog and digital sound circuitries are not independent. Different audio streams cannot be played to the

analog and digital circuitry. The selection of digital or analog output is performed through Sound pane in

System Preferences.

The sound circuitry and audio device drivers handle audio data in multiple formats. Both digital and analog

sound circuitry handle audio input and output data at sample rates of 32.0 kHz, 44.1 kHz, and 48.0 kHz at

sample depths of 16 bits and 24 bits.
