If you see video but cannot hear audio, check all of the following: 
Make sure the mute setting is off in your DVD player. Check the 
master volume setting in the audio Mixer. Check the volume settings 
in your computer speakers. Check the connections between your 
speakers and the computer. Check the Windows Control Panel/
System/Device Manager to see that the drivers are installed properly.

❑

A dirty or damaged disc may cause the computer to “hang” while it 
tries to read the disc. If necessary, reboot the computer, remove the 
disc, and then check that it is not dirty or damaged.

When I double-click an application icon, a message such as “You must insert 
the application CD into your CD-ROM drive” appears and the software does 
not start
❑

Some titles require specific files that are located on the application’s 
CD-ROM. Insert the disc and try starting the program again.

❑

Check to make sure you inserted the CD-ROM with the label side 
facing up.

My speakers have no sound
❑

Check that the speakers are plugged into the 

 connector.

❑

If the speakers have a mute button, make sure it is off.

❑

If the speakers are powered by batteries, check that the batteries are 
inserted properly and that they are charged.

❑

If the speakers use an external power source, make sure that the 
power cord is plugged into a grounded wall outlet or power strip.

❑

If the speakers have their own volume control, check the volume 
level.

❑

If the program you are using has its own volume control, check that 
the volume is turned up.

❑

Check the volume controls in the application, in the audio Mixer, and 
in Windows.

❑

If you connected headphones to the computer, you will not hear 
sound from the speakers.
