Most common origin is use of audio from iTunes.
Work around -
• Select needed audio to one new playlist
• Copy out this as an Audio-CD .aiff (not .mp3)
• Use this in the movie-project
Other origins are
1. strange / alient file formats as -
• .mp3, .avi, .wmv etc
• Convert them into .aiff 48kHz 16-bit and use this
2. the Mac is set wrongly in regard of midi -
• Close iMovie and other programs
• Start GarageBand
• Make a new GB-project and play some notes
• Close GB and Save
• Now try iMovie again
3. No audio when playback in iMovie 1 to HD 6.
a. in iMovie pref. - deselect ” Playback via Camera”
b. in System preferences - see that Audio out is not set to zero. Mine often does this
without me knowing why.
4. iMovie’08 & 09 & 11
• Toggle audio-scimming by cmd-K
Stuttering audio and video
1. FileVault is ON - Turn it off
2. More than 50 audio files in a movie-project
Mix down to one audio clip
3. Project is stored on one (USB) external hard disk - should be a FireWire one
4. the External hard disk is not Mac OS Extended formatted - but
UNIX/DOS/FAT32/Mac OS Exchange and this will not work for Video.
5. To little free space on internal boot hard disk.
I go for a minimum of 25Gb free space when project is imported and edited and this goes for
4x3 SD Video. For 16x9 HD my guess would be about 5 times more at least.
Neither Mac OS, iMovie or iDVD can address any other hard disk than the boot drive for it’s
scratch files. (Unlike Final Cut Express/Pro where You select scratch disk/s)
6. Network storage - DOESN’T WORK

Somehow the "Record From" setting was set at Built-in Microphone. I don't know when this happened but I did not make any changes from the last successful video capture.
It is working fine now that I changed it to "Built-in Input".
Your message back to me from the discussions gave me more direction in where to look for a solution.
