Please make sure you have an up to date modern browser, that your speakers are connected, and the volume is turned on by clicking over to an alternate website (like YouTube).
Verify that your speakers are plugged into the power outlet, turned on and up, and connected to the audio port of the computer. Your speakers or headphones must be plugged into the sound card not into the sound out jack of the CD-ROM drive. If you still cannot hear any audio, check your system volume settings and the volume on the media player. If your system is properly set-up, then try adjusting the system volume settings:
1. Click Start, Settings, and then Control Panel.
2. Double-click on the Multimedia Icon.
3. On the audio tab, turn up the volume.
If it is grayed out, this is an indication that the system is not configured for sound.
