I have a problem with one project that will not export the audio (it only exports the video). It does not seem to be a problem on any of my other projects, so it must be a setting in this project. I have gone through everything I can think of (checked audio, etc...) and I cannot figure out why this one project exports with no audio. I am directly exporting from the editor timeline, but when I tried exporting out of any comp it still has no audio. I am exporting to H.264 with an ACC Codec and a bitrate of 192kbps. The Export Audio is checked. I tried to export only the audio (I unchecked the video), the resulting file won't play. I changed it to export to AVI and the sound works fine. Any ideas why it won't export the sound as well to the MP4?
