Can't get audio and video speeds to play at original speeds
Sometimes this will happen from a verity of reasons. Sometimes the clocks are different. A lot of time it comes down to manual re-syncing.
Pick 2 sync points for the Video and the same 2 points for the audio. Make sure they are as far away as possible. Now divide the duration in frames between the 2

V dur / A dur = ratio


Now you have the ratio you should speed up or slow down the sound (sound is more pliable). Good Luck!
