With the appropriate applications and peripheral devices, the Apple IIGS can play music and even simulate speech. Even the stuffiest software uses a bell or beep to accompany an error message. The Sound option lets you change the volume of sounds and the pitch of beeps generated by applications.
This option works a little differently than the others. Instead of using Left Arrow and Right Arrow to move through a list of choices, you press Left Arrow to reduce the volume and Right Arrow to increase the volume. The asterisk on the indicator bar will move to the right or left, and you'll hear a beep to reflect your action. (See Figure A-7.)
