It's not clear what you're asking, David. What are "sound effects dials"?
Exactly which Audio Effects are you talking about?
Also, when one experiences GUI display issues (many of the Effects have animated settings panels), I always recommend that they go to the nVidia, or AMD/ATI Web site (depending on the mfgr. of their video card), download and install the very latest video driver. Even if that is not the solution to the display, it gets a common problem out of the way early.
Good luck, and please let us know just a bit more.
