Select your symptom from the following list:
• “No audio in Windows” on page 85
• “An audio disc or AutoPlay-enabled disc does not automatically play when it is inserted into a drive”

No audio in Windows
Symptom: No audio in Windows
Actions:
• If you are using powered external speakers that have an On/Off control, verify that the On/Off control is
set to the On position and the speaker power cable is connected to a properly grounded, functional ac
electrical outlet.
• If your external speakers have a volume control, verify that the volume control is not set too low.
• Double-click the speaker icon in the Windows notication area. A master volume-control window opens.
Verify that the Mute settings are not checked and none of the volume settings is set too low.
• Some models have a front audio panel you can use to adjust volume. If you have a front audio panel,
verify that the volume is not set too low.
• Verify that your external speakers (and headphones, if used) are connected to the correct audio connector
on the computer. Most speaker cables are color-coded to match the connector.
Note: When external-speaker or headphone cables are attached to the audio connector, the internal
speaker, if present, is disabled. In most cases, if an audio adapter is installed in one of the expansion slots,
the audio function built into the system board is disabled; use the audio jacks on the adapter.
• Make sure that the program you are running is designed for use in the Microsoft Windows operating
system. If the program is designed to run in DOS, the program does not use the Windows sound feature
and must be congured to use SoundBlaster Pro or SoundBlaster emulation.
