Audio problem: This appears to just be an issue on the Amazon Prime upload of this movie. But as Bond is walking out of the boar office with Lieutenant Hip, Hip is saying "He lives in a big house on a mountainside surrounded by guards." The S at the end of the word guards has a shuddering effect where it repeats and sounds like "guards-s-s." A DVD rip of this movie was checked and the audio problem was not there; it seems to just be on Amazon Prime's upload. (00:44:05)
Suggested correction: I don't see how this qualifies as a movie mistake. The problem seems to originate with the streaming service, not from the movie itself.
It is still valid even if it applies to a specific version of a movie or show, like the quirks with the Disney +/Hulu uploads of Family Guy having some image glitches here and there.
Audio problem: The voice of Lt. Hip, Bond's assistant in Asia (played by Soon-Tek Oh) changes during the film, usually depending on whether it's an inside or outside scene. In all the outside scenes, his voice is much higher and shriller, so it was probably dubbed by a different actor.
Audio problem: In the teaser we see the hitman load his gun when he gets ready to kill Scaramanga. When Scaramanga walks into the room, the hitman aims for him. The gun makes a loading sound. Upon the hitman's arrival to the room he racks a bullet into the chamber therefore no other action would be required to make the gun ready to fire. A loaded gun does not make a sound when you aim it - and why would he have unloaded the gun while waiting for his victim? When you load the gun, the hammer is back and the gun is ready to fire. No further actions are necessary. And a professional hitman does not wait to turn off the safety on his gun until his victim has arrived.
