Radio station bleeding through?

[Snïpëd]

Why do I keep getting a radio station bleeding through my headset when I connect to any vent but when I am not on vent its not bleeding through? Also my friends on vent can hear the radio station bleeding through my mic when I am talking aswell? Its been going on for quite a while now was hoping someone might have a solution. This is a brand new headset and a brand new computer only 4 months old so I know its not my headset or computer cause it only plays a radio station when I connect onto vent?
