opening unreal engines opens steavr

iv been away from unreal for a while and have only recently got back into it. however whenever i open one of my projects steamvr opens. if i close down steamvr it open itself up again several times. this isnt a big problem its just irritating because when steamvr opens it switches to the vive headphones and after i close steamvr i still have to go into sound settings to change it back to the speakers. usually exiting vr will switch back to my speakers. has anyone else experienced this or know of a fix? thanks
