ESX is a "lighter-weight" solution (in that it runs on the bare-metal 
rather than requiring a host OS that sucks up resources.  It of course 
is the most expensive solution but IMHO, it's worth every penny.  ESX is 
the only virtualization option I would care to put production workloads on.

VMWare Server can do sound, it's just that the default virtual machine 
doesn't include a sound card.  Just go to the settings for the VM, add 
new hardware and add a sound card.  Still Workstation does a number of 
handy things that Server doesn't, multiple snapshots for instance...
