It, like the rest of the virtual environment, is emulated. Have you installed the guest extensions in your WinXP VM? The extensions contain all the Windows drivers for the hardware that VirtualBox emulates. Also check your VM settings and make sure that: 1. you have a sound device activated for the Windows VM; and, 2. that you have selected ALSA for the sound driver (I think it defaults to Null Audio, ie no sound). </PRE> </BLOCKQUOTE> </BODY> </HTML>
