Try uninstalling and re-installing your audio drivers. If this doesn't help, your motherboard's sound module may have been damaged by a component failure or static discharge at some point. This happened to mine via a static discharge through my wired headphones. I solved my problem by installing a dedicated sound card and connecting my headphones directly to it. I actually got much better sound as the sound card (Asus Xonar DG) had an integral headphone amplifier.
There is also a possibility of electronic interference coming from either your motherboard or some other device attached to it. I've never been able to get decent sound from my front-panel headphone jack because its wiring is cheap and not shielded. I can actually hear my mechanical hard drive spin up through headphones attached to it. Front-panel jack audio interference is a common problem.
Headphones also can receive interference from external sources. I once had a headset/microphone connected to my landline telephone that played the local radio station in the background. Something in its circuitry was doing a pretty good job of being an old-fashioned crystal AM radio receiver. When I was a kid, one of my friend's mothers had a stove that played the local country music station from one of its burner coils.
When I was living in an apartment building and was still using a CRT monitor, the image would go crazy every time the lady in the apartment above me ran her sweeper overhead.
Speaking of interference. How long is your hair and how dry is it in your computer room? You may be causing the static yourself. I have to go barefoot when at my computer desk. If I wear shoes or socks I'm just asking for a static discharge. That's how I lost my motherboard's sound module in the first place.
