Well, my sound was popping and crackling in this game. I tried everything to get it to stop, but to no avail.
Then I realized something nly two other games on my system have popping and crackling sound when I play them, and I was never able to resolve it:
Soldiers : Heroes of WWII
Now, SH3 pops and crackles... What do all these games have in common?
I hate to add to the choir, but Starforce.
Chalk up another victory for throwing mal-ware copy protection devices into the system/device level of my computer.
