Explain - Can't do that
Tell how I do - Yes
• I only use .aiff 16-bit 48kHz or Audio-CDs (.aiff 44.1khZ) audio in my projects in iMovie or FinalCut
• in iMovie'08 to 11 - I export out as "Share to Media Browser" and as Medium - to be imported to iDVD. Audio still there
All other as .mp3 etc - I convert to .aiff via AudaCity (free from Internet)
or if from iTunes - Collected into a new PlayList ===> to a standard Audio-CD (no .mp3)
and the I use these .aiff files in my projects
I have about ZERO percent problems with my Audio - even on the DVDs (as I make my movies to this)

Thanks Bengt, but no. I converted the file to AIFF through GarageBand and still nothing. There are lots of other MPEG-4 clips in the show and most of them work fine. I can see the waveform in the iMovie window, it just won't play. It's almost like iMovie can't find the file - which is crazy because I'm creating new files and dragging them in - or that it is muted, which the Inspector tells me it is not.
Incredibly frustrating: I can see the waveform in the timeline; I can lower the volume; I can move the file, and I can hear it in the clip editor, but it absolutely will not play in the timeline. If I drag the audio file into another project, it plays fine. So, I'm giving up. There must be some kind of corruption in the project. I will start a new project. Does anyone know how to take the photos and videos from one project and bring them into a new one? I've tried copy/paste using just a couple of photos but it doesn't work.
I wrote this a time ago - anything of use ?No Audio
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

Sorry Bengt. I tried all of your suggestions (some before and some after reading your post) but no success. Then I noticed that there was an audio file later on in the project with a yellow exclamation point - meaning that iMovie could not locate the file (even though it was in a folder with all the other audio files). I deleted that file from the timeline and then dragged in the same audio file, after renaming it, and so far everything is working.
Thanks to everybody for their suggestions.
