Sound Issues - NHL Hitz 20-02

This game isn't covered under the game list but the game plays fine except for the sound plays very slow. I have no real experience with plug-ins or really anything as it pertains to emulators.

Also I was wondering if I could use Hamachi in order to play multiplayer with friends.

NICE work with the Dolphin emulator and a gr8ly appreciate the work y'all have put in and any help would b outstanding.
