Audio problem: When Bond takes the 'belt' off his tux, in order to get the concealed rope, there is a scratching sound, as velcro ripping. But the belt is not closed with velcro. We can see metal clamps when the belt lies on the ground and Bond removes the rope.
Audio problem: When Bond captures the seaplane with the money, he knocks out the pilot and throws him out. We can see that his body is limp when he falls from the plane. Nevertheless there is an 'aaaarrrrgghh' sound, as he falls. If he was awake, he would not have been as limp as we see - and in that event it is then clear it is a dummy being thrown from the plane.
Answer: Dalton was still contracted to play Bond in the next Bond film, Goldeneye. However, due to legal battles between MGM and EON productions, the film was delayed so long that Dalton simply lost interest and quit his role. He said afterwards in 2007 that, "I was supposed to make one more but it was cancelled because MGM and the film's producers got into a lawsuit which lasted for five years. After that, I didn't want to do it any more."
