Electrical noise

[The Belgian Waffle]

Hello and merry Christmas to everyone  

Have you got any idea why this happens?

 I'm asking because my MacBook Air is doing the exact same thing, but my Xperia z2 doesn't, and I'm fairly sure my phone is more powerful than this PC

Because of interference from various different sources. Probably some cross talk between the analog audio traces and power traces or io traces. Has nothing to do with how powerful the device is and everything to do with how the circuit board is designed.

 

P.S. your Z2 does it to an extent too. It may not be noticeable but there will be some degree of interference on the traces and cabling.

I see.. But why does my MBA do it only when I zoom in a document?
