Have you tried hecomi's uLipsync?

Hello, for my project I have to use a real time lipsync plug-in and hecomi’s (GitHub - hecomi/uLipSync: MFCC-based LipSync plug-in for Unity using Job System and Burst Compiler · GitHub) seems to be a really good option. Have you tried it with CC5 characters? Have you encountered any issues? For me it works perfectly, until I play an animation that gives the characer some kind of expression, then the blendshape sliders don’t work correctly. My main question is if that’s a problem with the unity import or the blendshapes themselves.
Thank you very much!
