Audio from one speaker

[Viktor12]

In the middle of the movie the half of the audio disappear. I have not done any sound settings. Why is that?

I can see in the timeline that the sound from one speaker is really low. The sound settings looks like when all sound is on

Hi,

According to me, the Audio file that you are using is a Stereo-type media, In which one channel has a proper/good-volume signal and the second channel has no/weak signal.
You can try to copy audio from strong signal channel to the weak signal channel, which will produce the same audio from both speakers. To do so, Just drag and drop "Fill left with right" or "Fill right with left" audio effect on media accordingly.

You can find the required effect with the help of screenshot given below:
