Check to make sure that the speaker or speakers on your computer are not muted. Look for the speaker icon in your System tray at the far right side of your Windows taskbar. If it has a red circle with a line through it over the icon, the sound hasbeen muted. You can change this by double-clicking the speaker icon and un-checking any checked boxes labeled "Mute" at the bottom. If the volume indicator is very low, drag it to a higher position.

Also, you are only able to hear sound effectswhen you are in "slide show" mode in Power Point.
