I do a fair amount of multi-cam and will nest the timelines into other higher-level timelines. Once in a a while I lose the audio in the higher level one (never the “multi” or “target” timeline) and all I do is the Sequence > Render thing, and if it wouldn’t let me then I delete the existing ones first.
Now that I think about it, I’m not sure it has happened in PPro Cs4 4.2 yet, but I can’t say it has been fixed.
