That and your CPU are to blame for slow speeds (and hence the sound issues). I have two computers with specs in that same ballpark; my advice: wait until you upgrade your PC (the whole thing) to play Dolphin, unless you want to stick to some of the "light" games. PCs like yours are better suited to office tasks than the kind of emulation Dolphin does. I used to be in your same position, but without a decent PC, Dolphin can really turn into an exercise in frustration pretty quickly.
