I need your help. Problems with volume.

Hi ; Im new using Audacity . Windows 10
I have a problem when I import the track to Audacity from my desktop
The track on Audacity gets crazy and it starts appearing different volume errors.
Volume goes down suddenly.

I send you a file. Please some technical explanation for this…

Thank you so much

The screenshot looks normal, though I notice that you have increased the track gain, which has caused “clipping” (overload distortion) on the 3rd phrase in the audio file “Volume Problems.wav”.
