I have a strange problem with sound. If i use Rapture 3d or software it makes no difference, what happens is for some reason the sound goes quiet for a few seconds then comes back. nothing seems to make this happen it just does it on its own. I know if i look back the sound changes but this is not the issue. I never have this problem in any other game i have and i have a 5.1 setup that has worked well for 3 years. Has anyone else had this and found a workaround?
