4 is pretty low, normally you need a low latency sound card to go substantially below ~ 50ms latency.

Setting buffering to lower than your sound card can handle is what causes the crackling.

There are relatively low-cost USB sound cards that do 8ms or so latency. I have an Edirol UA-1EX which is perfect, according to me.

It's a long shot but you can try selecting the name of your card instead of DirectSound. But basically you're asking too much of your hardware, I think. We won't know until you list your PC specs.
