I've now had multiple cases of audio loss upon export. The clips play fine in preview and timeline, but the exported video has completely mute sections that should include audio. There doesn't seem to be any rhyme or reason as to why some sections have audio and other's don't. Sometimes the silence lasts for under a minute; sometimes for over ten. I can go back and re-export the same sequence, and it will magically have audio, but I have no idea what's causing this. Any help would be appreciated.

If that doesn't work, try Preferences > Audio Hardware and set Input to None.
If that doesn’t work, try updating or rolling back your graphics driver directly from the video card manufacturer’s site.
If that doesn't work, try creating a new project and import the old one into it.
