I can't add new audio files to my project

[kinetic4307]

This is a very odd problem. My project has audio that is working, but when I add a new mp3, no sound comes out. The waveform is not even present in the timeline. It's like a shell of a file. There is nothing wrong with the mp3, it plays back fine in Premiere. I tried changing it to a wav to test but it plays back in super slo-mo. I've tried restarting many times as well as updating to the most current version. I'm at loss and have a project due soon. Any help would be appreciated.

Is the audio at a sample rate of 16K, 64K, 88.2K or 176.4K? There is a bug in the last couple of updates to AE for those sample rates. It is fixed in the AE beta, and will be fixed when 23.4 releases.

Thanks for the quick response. Yes, the file is 16k sample rate. Should I change it to another rate?

[kinetic4307]

I changed the sample rate to 48k and it works now.
