Audio problem: The original "gin machine" is entirely metal, but when Frank throws it on the floor, you hear porcelain breaking.
Requiem for a Lightweight - S1-E3
Audio problem: When Margie is saying she is impressed, Trapper replies "I should hope so", but his mouth doesn't move.
Audio problem: Right before throwing the football, Trapper says "Yo, Hawk!" but his mouth movements say "Hey, Hawk!" (00:09:05)
Audio problem: At the end, while Radar is playing drums, he is using drumsticks but drum brushes are heard.
Audio problem: In Blake's office, he's talking to Hildebrandt about Klinger, and the camera does a close up on Blake. You hear him say "Of course", and his mouth is moving a little, but not forming the words.
Audio problem: As Radar sets the clock back to 4:30, you hear ticking. The clock is electric, and wouldn't make a noise like that.
Suggested correction: Electric clocks do not necessarily lack a ticking sound. Depending on their construction, they may or may not have it. Older clocks are actually more likely to produce some sort of audible ticking sound, because the precise motor speed regulation required to build a clock with sweep seconds is much more difficult than producing an oscillator that outputs precisely one pulse every second (even if the clock in question does not have the actual second hand, that would still be true).
I bow to your observation and stand corrected. Thank you.
Audio problem: Toward the end, after it's determined that Radar isn't the baby's father, there is a vehicle horn honking. When the camera shot goes outside, the sound of the horn is a few notes higher that when heard inside.
Audio problem: As Trapper opens the door to the swamp and the football flies in, a splash is heard as if it hit a tub of water, followed by the sound of a high, fluted vessel filling with water. Neither of those sounds make sense in this case. (00:07:00)
Audio problem: At the end of the show, when Trapper is playing his instrument, the music does not match the movements of his hand.
Audio problem: As Hawkeye and Trapper get into the chopper, you hear the engine powering up, and the blades slicing the air, but the blades aren't moving at all.
Audio problem: At the end when Borelli is getting ready to take off, in the close ups you can see the main rotor blades starting to turn, getting ready to fly. But the sound suggests that the rotors and engine are already at full power.
Audio problem: When the soldiers in the back come flying through the window, you hear a window pane break and cullets tingle when the window is in fact a Japanese-style paper window. (00:43:40)
Dear Peggy - S4-E10
Audio problem: As Hawkeye calls for X-rays, you can see Klinger hollering a reply through the door, but nothing is heard. (00:21:30)
Audio problem: During the fight in Rosie's bar, a soldier is punched, and then thrown through the opaque window with the wood frame behind him. There is a sound of breaking glass accompanying the motion, but you can see the torn paper.
Audio problem: While trying to fix the projector, Klinger says, "The bulb is hot!", but his mouth doesn't move.
Audio problem: When the bulb in the projector goes out, Klinger is trying to fix it. People throw popcorn at him, saying "Find it!" After Potter says "Hit it, Father!", watch Klinger. From the wide shot to the close up, you hear him say "The bulb is hot!", but his lips don't move.
Comrades in Arms: Part 2 - S6-E13
Audio problem: When Hawkeye and Margaret are being driven into camp, everybody is cheering. Watch the driver of the jeep. He hits the horn button a number of times, but the horn is never heard.
Audio problem: After Potter convinces Saunders he still wants to live, the hiss from the anesthesia machine fades out even while Potter and Saunders are still standing next to it. Neither Potter nor Saunders turned off the valve again.
Audio problem: As Roy and Loraine enter the camp, you hear a "YEE-HAW" from Roy, but if you watch his mouth, you see he really says "YAHOO."
