The most important thing to do first is to go the HTC folder & find your sounds folder. Change the name of that folder to something else (for instance I changed the name to "original sounds". Then go to the folder under the same directory & find the soundpack file you wish to use & make sure that folder is named "sounds". The game will use the sounds in the folder named "sounds" by default. You can take individual sound files that you like from each soundpack & move them to the "sounds" folder (just be sure to move the specific file for that sound from the "sounds" folder or change the name so the sound you want will work.
