FIXED!

I made a profile just to leave this comment and hopefully spare others who are still suffering from the audio-rendering problem.

Most of the audio clips in my project were 44100 hz, but there was a batch of them that I had unknowingly brought in at 48000. Other posters had suggested that differing properties could be gumming up the renders, so I converted EVERY 48000 audio clip to 44100 in Audition. Voila! Everything worked as expected! I didn’t have to mix-down, flatten, re-import, swap files, or click “match source settings”. I just converted the files, Premiere automatically updated them in my project bins, and suddenly everything was peachy.

At first I converted just one audio clip and tried adjusting the work bar to render it by itself, but Premiere still got stuck. It was only after I made all of the clips match up to 44100 that it worked. Maybe that’s overkill and there’s some way to use some 41000 and some 48000 files in a single project/sequence, but I have no desire to find out. I just brought down the hammer and converted everything.

So if you’re still having problems, hunt through every audio file you have in your project, find the culprits, and turn them into 44100 clips.

Good luck!
