If there is problems with any of the soundspacks u install, it is on your end. The problems can be if you are using a Onboard sound card and not a pci or pci-e sound card. The sound packs will work problem fine if you use a dedicated sound card (pci or pci-e). Other problems can be you have modified the sound packs either by changing the sounds, rename files you are not suppose to, etc... Sound packs will take more resources to play with so makesure you have the hardware to use them.
