I am completely baffled on this one. The audio preview function in After Effects isn't working at all, whether I try to play the sound on its own or within a composition. I tried importing another file and applying a tone effect to a layer, neither of those played either.
I have checked everything I can think of. Sound on the clip is enabled, the waveforms look like they should. The sound works fine when I open the file with another program. I tried playing it with and without headphones plugged in with the volume all the way up, still nothing.
Whether I scrub through holding ctrl, hit (.) or use RAM preview, no sound comes out.
Audio preview is enabled.
Visually the audio levels fluctuate here as they should, but no actual sound comes out. Mute isn't on, as you can see there. Here is the file itself:
When I tried rendering, the sound WAS there in the output file. It's just previewing any sound within AE that isn't working. I need to sync sound and animation for this project so this is pretty debilitating as far as my work goes. I closed AE, restarted, etc., nothing changed. It seems like there must be some place that audio preview isn't enabled but I am out of ideas and no fixes I found on the forum so far have helped. If anyone has any ideas I'd be very grateful to hear them.
