Macbook pro 13 - Speakers buzzing noise crackling
Hello,
I have a macbook pro retina 2013 and in the last few weeks the laptop makes very strange noise. Sometimes it stops and let me work but sometimes I just need to walk away as the sounds won't stop buzzing, crackling. Just uploaded a video to make it easier to understand.
Do you know how I can solve this issue? Do you think if I will change the speakers this issue will be solved?
Thank you so much
