The Raid 4K & Italian Blu-ray Audio Sync Issue – How to Fix?

[majinkatana]

I'm looking to mux the 4K version of The Raid, but I've encountered an issue. The 4K version and the Italian Blu-ray have about a 10-second difference in the audio. The cuts are detailed here:

I have also checked the framerates of the video sources, and they are identical.

Has anyone dealt with this before? Any suggestions on how to adjust the muxing process to fix the audio sync issue would be greatly appreciated.

Thanks in advance!

It's not a muxing issue. The audio file wil have to be edited to account for the difference

How can I use it?
There are spaces where the original track should be heard, and then the Italian track resumes.
