Audio problem: In the scene where the polite leader is addressing the Sandins for the first time he takes his mask off and starts talking to the camera but he is muted until James unmutes him. If you watch the polite leader while he is muted he mouths the words "Mr. And Mrs. Sandin" before he is unmuted. However when he is unmuted we hear him finish that statement by saying "Mrs. Sandin" again. (00:33:25)

Audio problem: In the scene in the banquet hall, where the bad-guy is eating a carrot, he throws it on the floor. Subsequently, while chewing on the little bits he has left in his mouth, there comes a sound which is not a chewing-small-pieces-of-carrot sound, but a biting-a-piece-off-a-carrot sound. That sound was way too loud to have been produced by some little piece he had left in his mouth. (00:47:45)
Audio problem: While Gerry is talking to the C.I.A. Agent, a side view of the agent's face is seen as he says "That's the man in Jerusalem you want to see." The movements of his mouth and cheek does not appear to match up to what he is saying at all. (00:43:55)
Audio problem: In several scenes, Sandra Bullock used radio equipment in efforts to call for assistance. There is a sound made by vintage, mechanically tuned radios called "heterodyning" that results in a squealing, variable frequency sound in the speaker. While heterodyning added a degree of drama to the scenes in "Gravity", contemporary radios operate on a different, highly stable technique for tuning, and do not produce heterodyne sounds. (00:13:15 - 00:41:00)
Audio problem: The scene after Victoria drops the plant from Tech 49 and lets it fall onto the Earth, shows the two of them having supper.

(00:24:10)
Audio problem: In the scene after the jewelry heist when they go back to the house, Melander is questioning Leslie as to her connection to Parker. In one shot, you can hear the sound of him grabbing her and her making a high pitched whimper, yet he is not touching her and her lips are not moving. Also, Melander says "Check the house, every inch" and "C'mon, don't you want to hit me now" at the same time.
Audio problem: The helicopter appears in front of the window (like, a few feet away) of the command deck of a ship in the middle of the ocean, with the ship being in full alert and with guards all around the premises but who all somehow missed its deafening arrival. (01:35:50)

Audio problem: When Mindy uncovers her motorcycle and starts it for the first time in the film, the engine sound suggests that the motorcycle (which appears to be a Ducati 1199 Panigale) has a 4-cylinder engine (identifiable by the distinct smooth car-like sound with higher pitch). The Ducati Panigale has a 2-cylinder engine, which should be sounding a lot rougher. But in the end scene where Mindy drops Dave at his house with her motorbike, it makes a completely different sound, which is how the 2-cylinder bike sounds in reality. (00:14:10 - 01:34:25)
