Dynamic Link (CH -> AE) Audio doesn't work

I tried importing 3 Character Animator scenes with different Puppets and Audio in After Effects using Dynamic Link.

It was no problem with scene 1, but the puppet in scene 2 stuttered and scene 3 had no audio at all.

In Character Animator itself the audio is normal. I tried rendering it out of AE to see if there are any preview issues but the audio still didn't work properly. Also I checked the settings of the audio files and they all seem the same.

Importing them to a new After Effects Project was not successful as well.

Has anyone a solution? Might this be a Bug?

Edit: When I open the AE project I get this warning: " Audio conforming failed check media cache preferences"
