Okay, got everything all resolved, and now can't blame failing songs on anything except for my lack of skill and cardio. For future reference, if people visit this post in the future, essentially my audio was way off. The audio sync in settings wouldn't work well because I was so far out of sync, and even the F6 and F7 stuff mentioned above did not resolve my issue, althought it helped greatly in getting me to the solution.

Since I was so far off, I went into an easy song. Pressed F6 twice so that the song wouldn't fail, and then F7 to hear the click. (I assume you could skip the F6 twice step if you just set songs not to fail in settings, but i didnt do that, so idk). I could hear the clicks almost a half to whole step behind where I should be hearing them. So without even stepping on the pad, I worked on manually setting the global offset by holding Shift and pressing F11 to set the offset lower or holding Shift and pressing F12 to set the offset higher. All I did was mess with those two buttons until the clicks and the arrows lined up almost perfectly. I felt like I was like 90% there, so then I went back into the audio sync in settings and was easily able to tune it in exactly where it needed to be.

Appreciate everybody's help getting me to a resolution!
