This is a known issue for the most recent update -- the bug fix had a bug in it. For now, use AE CC 2014 to render video and audio if you can.
Как решить эту проблему в версии 2015?
I would EXPORT -- don't use the AE Render Queue -- the audio as a wav or aiff file.
Then I would RENDER -- using the AE Render Queue -- the video in a lossless codec. After that, I would use a different application to synchronize the audio to the video. Premiere Pro would be a good choice. From there, you can use Adobe Media Encoder to transcode to the final delivery specifications.
It's a lot more work, but it should do the job.
