FCP audio suddenly completely vanished and mute

[James Branch]

Have you tried re-linking the media?

Anything muted in the audio tool?

Try an Audio mixdown: Sequence Menu > Render Only > Mixdown.

Hello

Thanks, re-linking it didn’t work though… not sure what you mean by the audio tool? I’ve checked everything ten times and no mutes are selected from what I can see…

Hi John,

Thank you for the suggestion, I have tried that now and that didn’t work either.. any other ideas are very welcome, I’m at the point where I’ll try a ritual dance if there’s a chance it might fix this 🙂

In the Tools Menu select Audio Mixer. Then put the playhead where there IS audio. You should see a level indicated – probably it says “0” which means 0db – not zero audio. This is the normal default audio level. Now put the playhead where you hear NO audio. If it says “-inf” that means the audio volume was somehow reduced all the way. Then, try raising it with the vertical sliders in the Audio Mixer to 0. If on the other hand it says “0” then I’m stumped.

Hi again John

Thank you for the tip, I tried that too and all the audio tracks in use are on O even where there is no sound… So no progress. Could it be a bug in the software?

Now all of a sudden the whole of that sequence became completely muted without me doing anything… surely that must be a bug? Is FCP about to crash or something?

Is all the audio 48khz? Are there any audio renders? Are there plugins on the muted audio that are not in your system?

I would try deleting audio render files and see if any audio needs rendering. Check the ones that need rendering to see if it is a sample rate problem or mp3 file or a plugin.

Have you done the usual maintenance routine – Trashed preferences & repaired permissions?

Have you tried to copy a section into a new project & sequence to see if it will play. Does the audio register on the meter?

[Dinah Aslanzadeh]

Hello to all you supercool people and thanks so much for all the guidance and help… it was fixed thanks to your advice by clearing the render files through the render manager which I hadn’t done before… have moved the project around and changed the scratch disk a few times which I guess caused some confusion for fcp and I hadn’t found all the render files in the finder.
