It plays through built in speaker even when headphones are plugged in

Every thing is low quality chines junk these days and probably head phone jack input is broken and it is not repairable as all similar items ,

How to Clean 1 8 3 5mm Headphone Jack

DO NOT
-use compressed air, or use any form of liquid to clean the inside

This is the normal way for this laptop ..leave it always with the headphones on selected in that list ..cause if the main speakers don't work well there is no point in using them ..This way you will run whatever yo will plug in ..speakers or headphones..The only setting difference in headphones and stereo out ..is that for headphones will but the speakers of the laptop when plugged in ..This way it will even help you if the speakers are making weird noises cause they are damaged ..

I dont think the JACK is the problem, I suspect a bad headphone wire (intermittent) or an incorrect driver, headphone jacks in laptops are software controlled, (no mechanical switch inside) if you hear sound in both the headphones and the speakes it is a driver issue, try updating the driver, if the headphone wire is erratic it can fool the software that controlls the input and do crazy things also...

Good luck!

It is a mecanical problem, not in settings. The laptop's headphone jacks have builted-in switches that disconnect internal speackers when the headphone jack is plugged in. You need to replase headphone jack with a new one or manually desactivate the swith - must to get ino your laptop and have skills in work with soldiering iron

If you plug in headphones, do you have sound in them?
If so, then the problem is either the built-in speaker or the headphone jack.
If it's the speaker, then you're in for a pretty involved fix involving soldering little tiny wires. Do-able, but not for someone just learning how to use a soldering iron.

If it's the jack, then you might get lucky and fix it by inserting and then removing your headphone's plug.

I've had this style of jack get a bit of dust in it before, and basically think headphones are plugged in even when they're not.

Let me know if you've got sound in headphones, and we can take it from there.

go to the control pannel, then go to sounds and audio devices, then click the audio tab across the top. under sound playback, choose your speakers as the default device. solution only works like this for windows xp. good luck

Hello Again,

When you Plug in HeadPhones into the Laptop the Sound Playing should automatically Bi-Pass the Speakers and go Straight to the Headphones

-Unless there is a Faulty Input for the Speaker/ Headphone, Try Pushing in the Headphones More to see if the Speakers Turn Off

Posting solution to mark this as solved (even though poster already found solution):

Go into Settings menu, select Audio, and speaker output settings. The best is Auto, which will use the built in speaker only if headphones are not plugged in.

Believe it or not, not all speaker plugs, even if they are of the same size are NOT made the same.Some times the "male" PLUG pushes into the "female" socket in such a way that it makes NO connection or does not make the right connection causing the headphones not to work.
TEST: play music that u can hear through the internal laptop speakers, and while the music is playing, plug in the headphones.
The internal speakers SHOULD cut out, and under normal conditions the music should pass through the headphones.
If the speakers cut out and the headphones don't work, your plug is damaged.
If the speakers DON'T cut out after u plug in the headphones, your plug is open.
Depending on the audio circuit, your audio amp. inside the laptop is going to get damaged.
It depends on the WAY the audio circuit was made.
