Sound Effects Issue, Plz Help!

Windows 7, 64bit, 2012 US version. Actually used tifas bootleg for modding, worked perfect. Amazing mods, had fun etc...Sound effects worked perfectly fine until I got to about Cosmo Canyon, Gi-Cave area, until I noticed certain sound effects just stopped working. Im pretty sure I didn't change any settings. I use motioninjoy for PS3 dualshock play. I thought nothing of it, thinking maybe the game was just kind of laggy or something idk..so I eventually got to Lost Number boss and really noticed sound effects issue. I can hear the casting sound of a spell, but not the actual spell itself. Even with limit breaks I cant hear anything at first, but usually the last part of it. Melee attacks I can usually hear, but sometimes even those sound mute. What gets me is......I totally uninstalled the game. Reinstalled FF7 ( the original PC version game, with no mods ) and started a new game JUST to see if I still had the same problem and sure enough I did. Tried using Lightning and Ice and nothing, can hear casting sounds but not the spell itself. ANY HELP IS APPRECIATED! This is driving me crazy and I have tried several attempts to fix it, nothing is seeming to work. and to note my in-game sounds settings for both bars are set to 100. Its like out of the blue it just stopped working....again I would appreciate any help. Thanks in advance.

I would like to correct myself, I fixed the problem. Something as simple as a cable issue with my speakers. So for any of you who maybe have similar problems, check your speakers and cables, I just unplugged/replugged everything and bingo!
