Question Whenever I plug a pair of headphones into the front ports they have a buzzing sound

[BoltOLightnin]

Hello Everyone!
I recently started using a desktop pc for my online classes. There are headphone jacks on my cpu.
2 in the front( 1 green and 1 pink) and 3 in the back (1 blue,1 green and 1 pink).
When I use speakers to plug in to the headphone jacks on the back of the cpu there is no issue, but when I want to listen to audio using my headphones I plug my headphones to the green port in the front.

This is where the issue lies. The moment I plug in the headphones an incessant buzzing noise starts. I have tried restarting the pc and disconnecting the speakers to no avail. The buzzing sound is not affected by volume. This is a huge issue when I need to listen to something on my headphones.
Could someone help me out?

Are you using splitters on the heaphones? Reseat the connections from the case to the motherboard. May also just be a faulty jack. If you plug in the speakers to the front jacks to they also buzz?

I am not using splitters on the headphones. When I connect the speakers to the front jacks they also have static noise, but unlike the headphones there is only static noise. In the headphones I can hear whats going on albeit with a persistent buzzing noise.

Could you please elaborate on how I coud go about reseating the connections from the case to the motherboard?
Thanks a bunch!
PS: Would switching the ports in the front and back work?
