Hi @gamergrlashley ,
Does the headphone icon appear on the display when you plug in the headphones?
If not it may be that the headphone jack is either loose from the systemboard or is faulty and needs to be replaced.
Here’s a link to the [guide|60719] guide.
It is helpful as it shows how to open the tablet to gain access to the headphone socket.
Not quite sure but I think that the socket is an SMD type component (surface mounted device) mounted on the systemboard, so you’ll need SMD tools and expertise to carry out the repair.
If this seems too daunting, contact a reputable, professional mobile phone repair service and ask for a quote to repair the tablet.
