Short in Speaker Jack of my laptop

Hello,

There is probably a broken solder where the audio jack connects to the mainboard. If you are in warranty, then contact HP and they will fix it free of charge. If not, then pick up a usb sound card. They are cheap ($20), plug into a usb port, and have a speaker and headphone jack. This will fix it.

Regards,

Joe

it maybe that the cut off switch in the headphone jack has stuck as you place in a jack to the headphone socket there is a small switch that mutes the normal speakers and this should switch back on as you remove the headphones, this may have stuck. you will have to open the back and check the back from inside. try to short the mute and see if that is the problem. maybe squirt a small amount of contact cleanrer spray in the jack hole and insert and remove the headphone jack a few times this may resolve.

I hope this was helpful

Generally when the head phone jack is inserted the speakers will get disconnected automatically.

If you are going to use external amplifier you can try the AV sockets. Opening the TV you may require the special screw drivers some times.

Connecting Full-Size Speakers
1. Step 1 Insert the red and white plugs on a set of RCA audio cables into the right and left audio "OUT" jacks on the back of the TV.
   
2. Step 2 Connect the other ends of the cables to a free pair of audio "IN" jacks on the amplifier.
   
3. Step 3 Strip 1/2 inch of insulation from the speaker wires, and connect a pair of wires to the left and right terminals on the back of each speaker using the red wire for the right audio connection and the other wire for the left.
   
4. Step 4 Connect the other ends of the speaker wires to a pair of stereo speaker terminals on the back of the amplifier. The wires attach by raising spring-loaded clips on the back of the amp to reveal a hole for inserting each wire.
   
5. Step 5 Set the amplifier selector to the set of audio jacks connected to the TV to enjoy stereo sound from the television.
   
Connecting Self-Powered Speakers
6. Step 1 Insert the RCA plugs on the Y adapter into the TV's Audio "OUT" jacks.
   
7. Step 2 Connect the mini-plug on the wire attached to the right-hand self-powered speaker to the mini-plug jack on the Y adapter.
   
8. Step 3 Plug in the audio cable and mini-plug from the left-hand speaker into the Audio "OUT" jack on the back of the right-hand speaker.
   
9. Step 4 Connect the AC adapter to the power jack on the back of the right-hand speaker, then plug the adapter into an electrical outlet.
   
10. Step 5 Switch on the external speakers and adjust the volume.
    

Try it with an external speaker. The external speaker jack receives the audio from the scanner before it goes to the internal speaker. If the jack thinks there is still something plugged into it, the audio to the internal speaker is interrupted. If the jack is stuck, it may still work with an external speaker.

check the back of the computer, you will see a multimedia card, insert the speaker jack into the green port of sound card i.e the first port.

your microswitch is stuck. swab your earphone jack with light oil and insert in and out and around. This has work for me and others

It must be a hardware problem it can't be the driver which is software.If I were u i would have had a look inside the pc at the jack or ask toshiba for a repair/replace if in warranty but i think it's more likely the jack ur intrested in.Try putting a drop of water when inserting the jack(don't be affraid nothing can happen) and rotate it a bit and see if it comes only in the external device.This worked for me I hope it did for u.

That is not a software problem.
The headphones/external speakers jack socket has a switch to exclude from audio the internal speakers, when a jack plug is connected.
This is a very simple device and is not software controlled.
The fact that it has gone faulty at the same time you reinstalled the system is a coincidence.
If it does not mute when you insert headphones, all you can do is trying to play with the jack plug , inserting and pulling it out. If this does not unlock the switch, the alternative is having the jack socket replaced by a technician. This is generally an expensive repair, asthe socked is soldered on motherboard.
A cheap alternative to a proper repair is using an external USB to Audio Adapter and mute the internal audicard when using headphones.

The internal speakers should automatically be disconnected by inserting a 3.5mm jack plug in the audio out socket. It may be that your headphones or external speakers are using a 2.5mm jack which is too small to operate the switches in the audio out socket. Purchase a 3.5mm jack plug [cheap] and plug this in if it disconnects the laptops internal speakers then you need to connect accesories with the correct size plug.
