Audio problem: At the graduation in the beginning, the percussion section is playing on concert snares, but the sound those snares are making is that of Kevlar heads on a high tension snare. It is not possible to tune a concert snare to sound like that.
Audio problem: In most of the drumming scenes, the drumming usually doesn't match up, especially during closeups with Devon. This happens throughout the movie.
Audio problem: When Shawn starts to play his solo in the first game before Devon starts to copy him, take a good look at the way Shawn plays and notice how his left hand plays every hit while his right hand is doing that circle effect. When Devon comes in, take a look at what he's playing. it may seem close, but there are a few shots where you can easily see that he isn't playing the full part of the solo. He basically hits every accent in the shot right after he starts. Right before Devon moves in front of him, there's a close up of the arm circle effect while the other hand plays, but you can see Devons stick in his other hand which is not playing. In another shot he raises his right hand for the circle effect and his left hand is not playing while its supposed to, neither is Shawn, but you can still hear it. It helps to listen to the drum and watch the sticking. (00:44:55)
Audio problem: In the tiebreaker between MBC and Atlanta A&T, after the initial roll and cymbal players spinning their cymbals for effect, the section leader for MBC hits four quarter notes on his snare drum, but if you look closely, the sound is not synchronized with the video and he hits after the sound plays.

Audio problem: When Devon and Shawn are in the band room challenging each other, the printer makes the sound of a dot matrix printer. The printer that was actually being used was an Hewlett Packard all-in-one ink jet machine. They do not make the same sound. (01:20:00)
