Slight Hissing/Static Sound on Dell Precision M6800

I just got this computer used and it has pretty much nothing on it since its a fresh install/wipe. I get a hiss noise from my headphones when any sort of audio is played. If the sound is done after 1-2 mins it stops hissing. I have the most recent Realtek drivers. I have Dell Audio program built in. It does it with no enhancements on. Its not a power issue, hard drive issue since I have a ssd or fans noise. My OS is Windows 10 64 bit. Any help would be appreciated.
