Hi, I've been using after effects for a year now and I've never come across something like this. Usually when audio is being played back it goes really slow and distorted for a little bit and then once i play it back again it plays back fine. It will usually say that its not playing from real time or using enough RAM. This time, however, the audio completely messes up during playback not unlike how the preview is loading but it's playing from realtime? There's nothing wrong with the audio, this is a screenshot from when it's playing but its still going very slow and distorted. I've cleared my RAM and disk cache and still nothing. I have plenty of space on my laptop. I've also looked through the forums but there isn't really anything so I decided to make my own post, thank you 🙂
Impossible to say anything. You have not offered any info about your audio sources, preview settings, your computer, audio preferences and whatnot. And well, even when it "kind of works", this is still irregular behavior, so something with your computer or settings is pretty wonky to begin with.
