12:00 Midnight-1:00 A.M. - S1-E1
Audio problem: When we see the timer for the bomb on the plane, you hear the beep to indicate each second it clicks down. However, we see the timer say 24 seconds. We hear several beeps and 7 seconds later the timer says 20 seconds. The key point of the program being real time, so the timer should be on 17 at least. (00:37:30)
Audio problem: Alan gives Teri the address near the end and says they should tell the police. Teri responds that "Jack is the police" however this line is a clear overdub as the audio is completely different to the rest of the scene. (00:36:50)
Audio problem: When Jack and Rick are talking in the water tower, a lot of the audio in that scene is either out of alignment or overdubbed. Easiest to spot is when Jack is checking Rick's wound. (00:10:30)
Audio problem: When Jack is getting suited up, the new bloke arrives and we hear him put his case down on the glass desk. Camera changes and we see him put the case down on the desk a second time. (00:12:50)
Suggested correction: You can see George (replacement to Alberta) holding 2 briefcases just before Jack sits down to put his shoes on.
11:00 P.M.-12:00 Midnight - S1-E24
Audio problem: The coast guard confirms no body was found and that they cover 50 miles of coastline. As he says about the distance his mouth isn't moving. (00:27:15)

Day 2: 7:00 A.M.-8:00 A.M. - S2-E24
Audio problem: In the french-dubbed over version, in the last seconds of the episode, just after Palmer has fainted and the camera is zooming out and the sound is fading, you can just make out his secretary shouting "Help", in english.
Day 5: 3:00 AM - 4:00 AM - S5-E21
Audio problem: In the scene where the President Logan is in his office and planning to take his own life, he gets a phone call from CTU's Miles Papazian. When President Logan answers the intercom, his voice sounds like he is the one talking through the intercom, eventhough the camera stays on President Logan. After answering the intercom, his voice changes back to normal.
Day 7: 5:00 PM - 6:00 PM - S7-E10
Audio problem: When Dubaku sees Jack and Renee closing in on his car, he tells his driver "Go! Go!", but his mouth doesn't move. (00:09:05)
