What I am looking to do is to run three OS's on my system at the same time or with out rebooting the system. What I am looking to do this. Is to run Ubuntu Studio and MS Windows for audio production. I have tried VMware and Virtual Box, but I have a big issue the virtual sound card. Any ideas?

The the issue with the sound card is the Virtual environments have a set sound card that don't have the abilities to do any type of audio production. Its has AC'97 or Soundblaster 16.
