Issue:
- When my headphones are connected to my workplace laptop there is some persistent buzzing and crackling static type noise that comes through.
- This stops when the Ethernet cable is unplugged.
- It also stops when the volume is dropped to zero, although it isn’t sensitive to what the volume is when it’s non-zero.
- I can’t hear the noise coming through the laptop speakers when the headphones are unplugged (although I’m in a noisy environment so it's possible it's still there and I just can’t hear it).
- The noise does seem to fluctuate when sometimes my browser (Chrome) loads new webpages.
- Other sound plays fine, including streaming music.
- It seems highly affected by transfers across the network too. So it’s more likely a network thing than just the Internet.
Computer details:
- Dell Latitude E5470

Headphones:

How can I fix this and remove the noise?
I haven’t found similar questions on this site helpful for my issue so far, and none have the specific Internet-related crackling I’m experiencing.
