Apple 640 manual Turning on PC sounds, Choosing a setting in the Sound pop-up menu

Turning on PC sounds

To have Sound Blaster and other PC sounds played through the Macintosh speaker or through headphones, you need to specify settings in both the PC Setup control panel and in the Sound control panel.

Choosing a setting in the Sound pop-up menu

The Sound pop-up menu in the PC Setup control panel gives you three choices:

mTo hear PC sounds in both the PC environment and the Mac OS, choose Enabled.

mTo hear PC sounds only when you’re in the PC environment, choose Auto Enabled.

mTo shut off PC sounds entirely, choose Disabled.

Sound control panel takes precedence: The setting in the PC Setup control panel’s Sound pop-up menu has no effect on sounds generated in the Mac OS. If the volume is set to 0 in the Sound control panel, however, you won’t hear any PC sounds no matter what the setting is in the PC Setup control panel’s Sound menu.

For sounds generated by the Sound Blaster card and for sounds from the PC, the Sound control panel must be set with the Internal CD playthrough option turned on. For instructions, see the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.

The PC sound setting in the PC Setup control panel does not affect sounds produced by the Sound Blaster card. Only PC-generated sounds, such as the system beep, are affected by this setting. To turn off both PC and Sound Blaster–generated sounds, use the master volume control of the Mixer Control application program from the Audio program group, or turn off the Internal CD playthrough option in the Sound control panel in the Mac OS. (For instructions, see the “Sound” topic of Macintosh Guide, available in the Guide (h) menu.)
