Once I switched to Vista, I noticed that there wasn't a "Mic Boost" option anymore for my vox. So after a little research on the Creative forums, I found these:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0007\Settings "MicBoost"=dword:00000001
Be sure to reboot after making any changes to your registry. You still won't find the check box for the "mic boost", but it will be enabled.
Skuzzy, I'll be hosting those links until Creative Labs or Microsoft fixes the mixer. Feel free to add them to your Vista Help sticky.
