I'm taking my projects out of Final Cut Pro X and sending them to Compressor 4.  No matter what settings I choose, I can't get audio out of my compressed files.  I have sound in the preview window, I have audio settings in the inspector (they won't highlight so I can't touch them though).  This should be more simple than it appears right?  It's Compressor 4.0.6.

Compressor, Mac OS X (10.7.4)

    What kind of output files (format) are you trying to make – working off which presets – and for what intended use?

    The formats are constantly changing, I'm producing and delivering to television broadcasting stations in different markets.  Here are the specs for the file that I'm dealing with now. 


    Video Specs:

    File Extension: .mov

    Center-cut Safety: Required

    Compression Codec: H.264

    Resolution: 1920x1080 (1080p) (center-cut safe)

    Frame Rate: 29.97 fps (constant/fixed)

    Video Bit Rate: 30Mb/s — if possible, select "Restrict to 30Mb/s" in the Data Rate pane

    Scan Type: Progressive (1080p)


    Audio Specs (AAC option):

    Audio Type: AAC

    2 Channel Stereo (Ch1, Ch2)

    No SAP or Descriptor Audio

    Sample Rate: 48khz

    Bit Rate: 250Kbps-384kbps


    I'm spot on with the video specs unfortunately I'm having nothing but difficulties with the audio.

    A couple of more questions if I could:


    Are you working with an H.264 sequence in FCP?


    If you mark a short range in your timeline and export that as a master file, do you have sound if played in QT Player?


    In Compressor, what h.264 preset did you use – or which one served as the basis for a custom preset? (There are several ways to build a custom preset in Compressor.)


    In the Video Settings tab, is audio enabled?


    Could you post a screen shot of your summary pane from the Inspector?


    Guess that's more than a couple.

    I've figured it out and I guess I'm not terribly proud to admit it.  I've been using the Send to Compressor feature as opposed to Export File>Open With Compressor.


    I appreciate the support Russ H!  Thank You
