audio playback
I use FCP 4.0 and I was playing back an entire sequence, when the audio suddenly cut off. It was playing fine at the beginning. Could there be something wrong with my settings?
1) audio goes all the way to the end
2) it show waveforms all the way to the end
3) just two layers, left and right channels
4) the sound stopped altogether everywhere. One second the sound was playing and the next it wasn’t. I checked itunes to make sure it wasn’t a speaker or computer thing, but that worked fine.
5) I had just imported the video clip and dropped it in the timeline, but I hit Apple-Option-R just for the heck of it. -

There is a function in FCP that is often overlooked… and it can help with many audio and video “skipping”, “sticking” and “missing” problems.
You should “Mixdown” the Audio for playback before you dub out of FCP, or during the edit, if you have audio/video stuttering, drop-outs, sync-slippage, or freezes.
NOTE: Mixdown has even been demonstrated to help with slipping, skipping problems (or “missing” audio clips) for files being EXPORTED as QT (or similar) files out of FCP.
First, SELECT ALL of your audio tracks (highlight them) on the timeline, then:
Sequence Menu > Render Only > Mixdown.
You should see a dialog box telling you its rendering.
It might seem to make little sense that “Mixing down” even simple audio tracks will “fix” complex video “freezes” or random audio dropouts to tape or export, but it CAN.
NOTE: It does not matter of you only have one audio track, if there are random freezes during output, you should try the Mixdown.

Another thing that we haven’t asked…
Right-Click (control-click) on the file in the browser window and look at item properties. What does it say for the audio there? 48k? Any compression? 16 bit?

Also upgrade to FCP 4.1.1.
