Любой звук или музыка, добавленные в Adobe Rush Version 1.2.12, звучат как шорох

What needs to be done to use sound files in Rush? Until now, nothing has been added when they are added - any sound on the soundtrack is reproduced as a rustle. Normally, you can hear only the sound that comes immediately from the video. And if I take music or a separately recorded sound file and put it on the sound track, then again we get a rustle.

I have installed version Rush 1.2.12. I'm mounting the video on Mac Book Pro. It has the latest software update installed. Sound files in any format are reproduced as rustling - waw, mp3, m4a. 

And another question: how can you separate the sound from the video to place it on a separate sound track?
