Static playing through front headphone jack only

So recently i went to fries electronics to pick up a lenovo 710-90F to use as a computer desktop for my DAW, but when I plugged in my headphones into the front jack, a static noise occurs while playing the audio i want. Only in front jack, not the back… (problem is not due to my headphones, and tried multiple other pairs…) so i then returned it to fries to get a replacement assuming something was wrong. When i took home the replacement computer, the SAME THING happens… Is it possible 2 computers are bad?

Its A kind of staticy feedback noise that seems to get worse when I open an application or really do anything.

Could my headphones being made out of aluminum cause this?

Some one help me problem solve this please! I'm Thank you

Inside the case the wiring goes from the motherboard to the port in the front plate. If there's no ground shield around that audio wiring, fan motors, power supply, video electronics radiation waves could cause the static.
Get an extension of the headphones cable and use the rear port only.

Buy a different make lenovo are very flimsy - a recent one I had dealings with had the power socket glued to the motherboard!

The "Sound card" type electronics in PCs are never all that high quality with analog audio.

Some level of background noise is common - the CPU takes massive amounts of current in short bursts & that modulates the power supply voltages and ground voltages throughout the computer, affecting any analog audio circuitry and connections.

Cross-linking the PC audio with any other form of internal or external ground, or connection to other powered & grounded equipment, often makes it far worse.
I'm guessing the front panel connectors are also grounded to the case or USB wiring in that particular machine.

The PC "sound card" style setup also has large amounts of buffering to minimise CPU load - but that adds delays/lag to real-time audio.

Generally, the only way to get acceptable audio performance with a DAW is by using an external audio/midi interface.

Look at something like a Focusrite Scarlett 2i4 as a "starter" unit.
You can then totally ignore the PC audio and get perfect quality in and out of the DAW.

Open your sound software and see if your microphone is turned on and if it is turn it off because that will cause static and feedback if that does not cure the problem take that computer back and go to a store where the isn't a problem they may have a batch of bad computer and yes that's possible
