Sure, it may just not be enabled. On Windows PCs, you may have to go to the Control Panel and go to the SOUND tab. There you may find that you have to choose between the default analog sound out and the digital sound output thru the HDMI cable. If your system has an audio manager application (Realtek for example, uses one), you can select the digital output there as well. It may even be easier to do there.

This is most likely a simple driver glitch. You can fix it by uninstalling the audio drivers from the device manager, then reboot. The machine will find the sound card and reinstall the drivers automatically. This should fix it, if not let me know.
THe realtek Digital Output will only output sound if you have an optical cable attached. this allows you to connect your laptop a audio receiver via an optical cable. this is why you get no sound when it is set to digital output.
