Ok, so I reset from receiver, reran YPAO, turned off YPAO, DRC, etc, everything off. After it was finished, it actually asked if I wanted to turn YPAO volume on. Anyway, now I'm starting to think it's the sub. While going throught this for the past week, I've been checking to make sure my crossover was set at 80hz (also tried 90, 100), because it seemed like the front speakers were distorting. I listen to music with the sub off, with a bass heavy song and no issues. My sub volume seems to be all over place, can't get the it to all blend. I didn't touch anything from the YPAO other setting other than making sure all speakers are set to small and raise the gain on the sub to about 1 o'clock, where I had it before. (I had to have it at 9 o'clock get the the receiver to set it at -9.5) I popped in Bad Boys III, which supposedly has an amazing Atmos soundtrack and lets say the bass was way to boomy, I turned it down one click on the sub and then I had no bass. It's so strange.
