Hello!
signed up specifically to report this issue. Tried everything but audio crackles/corruption happens no matter what format, render speed or even PC I tried (tried 3 different ones, all Windows 10, very high spec workstations). As far as I can tell it has nothing to do with mass storage, video cards, or audio interface. It appears to be just a bug in the audio rendering - it does not even need multiple audio clips or video to show up. I took my project, deleted everything except the music track, rendered and still got corruption.
One thing that's true is that reducing the render speed *mitigates* the problem, and you might not notice it anymore, but there could still be corruption. In one of my tests at render speed 50 the crackles were gone, but there were definite artifacts in two locations that I could have easily missed had I not specifically been looking for problems. And no, these were not compression artifacts, but definite digital distortion.
At the end, for this project, since the only audio was a stereo music track, I rendered the video with Resolve, then imported into HitFilm, added the audio and rendered with the same settings. No audio problems at all.
Hopefully this gets fixed in the next beta, since b3 is unusable as is.
