Audio problem: When Troy and Gabriella are singing "Everyday," Troy sings with his microphone away from his mouth numerous times during the scene, yet he is still heard just as well, and not at a lower level, like he should be. (Within the context of the film, this is sung live on stage and is not implied to be pre-recorded.)
Audio problem: Near the end of the song 'Everyday' when everyone in the circle has moved forward to the centre of the stage, Troy turns back to the audience singing 'everyday' and you can hear Gabriella's voice but her mouth is not moving at all.
Audio problem: During 'You Are The Music In Me', when Troy lifts Gabriella off the piano, Gabriella mouths the words 'Oh yeah' then three seconds later her voice is heard without her lips moving.
Answer: Although the dialogue makes it hard to follow, the game was actually a challenge between Ryan/Gabriella and Chad. If Ryan's team won, Chad and the guys would have to perform in the talent show; if Chad's team won, Gabriella and Ryan would have to forget the whole thing. Ultimately Ryan won the respect of the guys even though his team lost the game hence Chad asking what would he have to do in the show.
