I just created a project using Movie 11 but I can't hear any sound....any ideas?  I shared it in iTunes exported in Quicktime...found it using Finder in movies but I can only see the audio....

iMovie '11, Mac OS X (10.7.5)

    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

    Yours Bengt W
