iMovie suddenly mutes all of my voiceovers and music!
I have iMovie version 9.0.4.
So first these yellow signs with exclamation marks appeared on some of my music, but all the music seemed to work fine. Then after I finish editing some text, the music nor the voiceovers or the music without exclamation marks was all completely silent, but the video audio was fine.
What happened?
iMovie '11, Mac OS X (10.6.7)
