The sound device that VirtualBox creates for the virtual machine is not the
same as the one on your motherboard. 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).
