I have an HP ze4145 (Laptop) and my headphone jack after 2 years has broken on me. Before it completely broke I would have to move the plug around inside the jack to try and get the right connection. Now that im completely missing a headphone jack I have two questions. First, is there any way i can disable the jack and force all of the audio to come out of my laptop speakers? and Second, Would i be able to buy a new jack or soundcard and how much would it cost on average? Thank you to anyone who can help.
