Halo 2 MCC: Strange "beep" on LatAm dub

Hi there
Recently I played Halo 2 on OG graphics to see the new improvements, it looks fantastic just as I remembered on the classic Xbox. Then I found out a little problem, it seems that dialogues (at least on LatAm spanish dub) has some strange “beep” everytime a character talks. I’m not sure if this happens on other dubs but it’s a little annoying. I hope they can fix this soon.

Also I posted it on twitter with a video as evidence so, hear it for yourself
