Audio problems
Problem Solution
The audio cannot be heard on the Windows
®
operating system.
• If you are using powered external speakers that have an On/Off
control, ensure that:
– The On/Off control is set to the On position.
– The speaker power cable is connected to a properly grounded,
functional ac electrical outlet.
• If your external speakers have a volume control, ensure that the
volume is not set too low.
• Click the volume icon in the Windows notification area on the
taskbar. Check the speaker and volume settings. Do not mute the
speaker or set the volume at a very low level.
• If your computer has a front audio panel, ensure that the volume is
not set too low.
• Ensure 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 audio connector.
Note: When external-speaker or headphone cables are connected
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. Therefore, you must use the audio connectors on the
audio adapter.
• Ensure 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. The program must be configured to use SoundBlaster Pro
or SoundBlaster emulation.
• Ensure that the audio device drivers are correctly installed.
The sound does not come from the headset
or headphones.
Select the headset or headphones as the default audio output device
in advanced sound settings.
The sound comes from one of the external
speakers.
• Ensure that the speaker cable is inserted completely into the
connector on the computer.
• Ensure that the cable that connects the left speaker to the right
speaker is securely connected.
• Ensure that the balance settings are set correctly.
1. Right-click the volume icon in the Windows notification area
on the taskbar. Then, click Open Volume Mixer and select the
desired speaker.
2. Click the speaker icon on top of the volume control, and then
click the Levels tab.
