In what format is Your music ?
• .aiff + freq. + bit depth e.g. 48kHz 16-bit ?
• from iTunesNo Audio in iMovie
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 WORKNo audio on DVD disc.Most common origin.
1. Imported audio from iTunes.
• In iTunes copy out as an Audio-CD .aiff (Same as played on standard Stereo CD - no .mp3)
• Use this in Your movie project
2. Low - Free Space on Start-up/Boot/Internal/Mac OS Hard disk makes it hard for iMovie to work as intended.
Down to 1.3 GB and it doesn’t work - especially audio don’t migrate over to Media Browser
(iM’08 & 09)
3. Material in iMovie’08 & 09 - Shared to Media Browser and here selected as Large
large.m4v. It silenced out this project in iDVD. By making a slight alteration - provoking it to ask for a new Share/Publish to Media Browser and here selecting 640x480 - and audio was back when a new iDVD project was created including this movie.
Minuscular - - 176x144
Mobile - - - - - 480x360
Medium - - - - 640x480
Large - - - - - - 720x540 960x540
HD - - - - - - - - 1280x720
4. Strange audio formats like .mp3, .avi etc.
• Change them to .aiff. Use an audio editor like Audacity (free)
5. Main audio is set to off in System Preferences - Does this by it self - Don’t know why
Cheque Audio-Out resp. Audio-In

Had the same problem; some Googling around gave me a kludgy, but effective fix
Downgrade Perian from recent versions back to version 1.0.
That worked for me, and so far I haven't encountered any deficiencies — except it takes more advanced versions of Perian to enable QuickTime to handle subtitles in .srt format — that I have noticed.
7. GarageBand fix.
In this set audio to 44.1 kHz (Klaus1 suggestion)
(if this don’t work try 48 kHz - me guessing)

Before burning the DVD.
• Do a DiskImage (File menu and down)
• Double click on the .img file
• Test it with Apple DVD-player
If it’s OK then make Your DVD.
Burn at x1 speed.... (or x4)
• In iDVD 08 - or - 09
• Burn from DiskImage with Apple’s Disk Utilities application
• OR burn with Roxio Toast™ if You got it

.mp3 - that's what I DO NOT use
I convert all to either
• .aiff 48kHz 16-bit - or -.
• .aiff 44.1kHz 16-bit (from Audio-CDs)
And I use Audacity™ to do this - FREE on Internet - nov version 2.
And by not using
• .mp3 or other ailient format
• direct from iTunes (I do an .aiff Audio-CD first)
I have very few problem with my Audio-Works
Yours Bengt W
