Audio Clipping Problem

I have a small puzzle game, where you merging squares together. There is just music in the background and some sounds when you play (moving, merging, teleport, etc.).

But I have a problem with clipping audio. I attached also an audio example. Clipping starts at 10s.

AUDIO EXAMPLE HERE

Of course, I have checked possible solutions here on the forum, but no one works. What I have tried so far is:

1. I turned off Doppler Level on the audio source and also in project preferences

2. I turned down the volume on the audio source and also in project preferences, so when sounds and music is layering, clipping should not occur.

3. I have checked audio files and no one is clipping itself.

Do any of you have an idea how to solve this? Thank you very much for any help.
