Sound only works with headset. No longer comes

goto your device manager and remove the headset , your speakers should work again

You need to Purchase some Amplified PC speakers as a lot of computers come without Built in Speakers

Hi Ted,

This kind of symptoms indicated of fault either the internal speakers or the earphone jack itself. To isolate where the fault came from, the speaker's resistance inside the set needs to check using the multimeter/ohmmeter.
Watch the video below to give you an idea how to test the speakers.




If the speakers are in good condition, then the fault came from the earphone jack itself. It has a built-in switch that will open/closed once you plug in your headset to cut the sound coming to the internal speakers of the TV and hear the sound only to your headset. The problem is, if the contact stuck or dirty, the sound will not pass through the speakers. You have to spray it with electrical contact cleaner while inserting and pulling the headset plug to clean the contact.

Hope I helped you.
Have a nice day!

KINDLY VISIT TO ANY HARDWARE ENGG WHO CAN REPLACE OR REPAIR SOUND SWITCH/CONTROLLER

Hi,

Welcome to FixYa!

What do you mean it stopped working? No sound at all?

Please try the following:

1. Please make sure the sound is not set to mute. Try to adjust the sound volume.

2. Reinstall the audio driver. You can do this using the drivers disc that came with the computer or you can download the audio driver from the computer manufacturer's website: http://support.lenovo.com.

3. Try to connect an external speakers or headset. If you can hear sound on an external speakers or headset then the internal speakers of your laptop is already defective.

Hope that helps. Thank you for using FixYa!

Go to sound settings in control panel and check each and every tab and you will find it simple.....goodluck!

Sometimes the headphone jack has its own volume control separate from the internal speakers. Check the levels in the volume mixer.

• after all the testings of the external devices, one thing proves that the internal speaker needs replacement.
  

Connecting headphones to the system will disabled the internal speakers until the headphone jack is disconnected, at which such time the internal speakers should function again.

If you disconnect the headphones and the internal speakers are not re-activated, then there may be damaged to the microswitch in the jack. (Try rebooting after the headphones are disconnected too)

MUTE THE SPAKER SOUND AND ADJUST THE SOUND SETTING FOR HEADSET
