HLS does not have sound or video

[DevineDecrypter]

Hey, im using the same HLS link on android and ios, on android everything works fine, but on IOS no sound or video gets played, events work, like i can know the video is playing and moving forward, but nothing is displayed nor can be heard from it.
here is an example link: link

Whats interesting is that the AD gets played, it has both sound and video, the ad is Vast2.
