I have an Audio Loses in audio tracks

I am recordig a guitar track, with two channels with my scarlet focusrite, and i can see that everything looks ok, but when i am listening the recording, in the mic channel, i can listen just a part of the recording is like the another part the volume is down and in other parts the volume is normal. I dont know what is the problem.

I don’t know either.
Can you see the volume changes on the waveform of the audio recording?

Maybe you can make a screenshot so that we can see the waveform? Try to make it big like in this example:

I Just found the failure, i guess, I re installed the software of scarlet focusrite, and put the computer on high performance and closed all the another programs and cubase work perfect!!. Thank you
