I suppose you have the right to do so, but it's a shame you crippled an absolutely perfect solution to provide sound (via Lion kexts, no less) to a defective sound implementation of Snow Leopard Server by VMware. In the hope that you won't use your censorship rights, here's what anyone interested in providing sound to their Snow Leopard Server Virtual Machine should do:
1. Disregard the very bad advice of using the Ensoniq driver.
2. Add a virtual sound card to your Snow Leopard Server virtual machine.
3. Look for the following Lion kexts: AppleAVBAudio.kext, AppleFWAudio.kext, AppleHDA.kext, AppleUSBAudio.kext, AudioAUUC.kext, AudioIPCDriver.kext, IOAudio2Family.kext and IOAudioFamily.kext and copy them to your Snow Leopard Server desktop.
4. Find a copy of KextBeast and run it in Snow Leopard Server. It will install the relevant kexts.
5. Upon reboot, you'll have sound. Delete the kexts and KextBeast from your desktop.
