I'm running an Auzentech Prelude
There are two ways to enable mic monitoring through this sound card and it would be the same with any creative driven product. Most likely very similar for others as well. The first and best way is with the software included with the card. There is very little delay when using this method on my computer.
The second way is through windows as displayed below. This method for some reason produces a horrible amount of delay, but it works.
