I would like to have the sound card of the guest OS used by that of the host OS. So far I've tried the following:

Win XP SP 3 (trial) - sound card was detected automatically by the host OS, however the activation expires after 30 days. Fresh installation from an OEM version.

Win XP 2008 64 bit (pre-configured desktop etc) - sound card does not work.
I tried to install the original drivers by:
1. From VM Ware settings updated Specify host adapter to C-Media Wave Device (which is the sound card driver on the Guest OS)
2. The hostOS detected the sound card as requiring the driver to be installed.
3. I tried installing them using windows (auto detect) and using the original drivers that usually work (unsuccessfully)

Ux host OSs i.e. Kubuntu, Red Hat Fedora - no sound; drivers probably not available

Driver on guestOS: C-Media PCI Device
Sound card: Creative Labs 5.1 SB-0220 (old one!)

Has anyone encountered similar problems?
