Audio/video sync problem (23,976, 48kHz)

Hello everyone! Sorry if I make english mistakes, it isnt my native language.

I've seen lots of different topics about that kind of common issues, but I haven't found anything that really helps me.
I've shot a video (live music video in a recording studio) with 3 cameras, all the same brand with the same frame (23,976) rate and settings.
The audio was recorded separetely on a ProTools session, 48Khz.
I've done this lots of time, the exact same way, and I've never had a problem.
But this time, my audio won't sync.
When I add my audio to my timeline, it is slightly faster. If I change my audio speed to 99,92%, it works (or at least the offsync isn't noticeable) but I'd rather not affect the audio quality.

I've tried exporting my audio in different format, but once uploaded into Premiere, they are all exactly the same length. I've also tried to import my files in a similar project (24fps with audio recorded in 48kHz separetely), but the problem stays. Everything is in 48kHz (audio interface, every setting).
I've exported an excerpt of the video with the original camera audio to import it into ProTools, and it won't work there either (and actually, the audio length was slighly longer than the video file somehow?)

I feel like there is something very dumb that I'm missing, sorry for not figuring it out before if it's the case!

Thanks a lot,

Rémi
