Headphone jack of my laptop does not work properly. I get sound from both the laptop speakers and in the headset. So i bought a USB audio device. Still the sound comes from laptop speakers and there is no sound in the USB headset.

The Laptop has 3 Ports on the side- Pink,Green,Black
Pink Port is LineIn for an external device player jack

Green Port is LineIn for the Microphone jack
Black Port is LineOut for Headset or External Speakers jack

Plug the Green jack on Headphone - into the Black Port on the laptop.
b) Go to Control Panel and open - RealTek HD Audio manager
On the top of Page are 3 Icons -

One Icon is labelled Speakers One is for Digital optics, one is for Mic,
The Speakers Icon is misleading as it is also for Headphones (LineOut)

Select Speaker Icon and make it Default. Also tick Full Range - Front LR
Ignore the 4 vertical Analog Icons on the right side.

You should now have Headphone sound if your volume is not Muted.

click start control panel on the left select hardware and sound then select manage audio devices then recording you should see a microphone right click select enable windows 7

click start control panel on the left select hardware and sound then select manage audio devices then recording you should see a microphone right click select configure speech recognition then

you will see earphones with a speaker among a list set up a microphone headset with microphone then next and next again you should see your earphones with microphone being configured

click start control panel sounds and audio devices select advanced there might be a tick in the mute box untick it or select audio from the microphone drop down list

make sure you have the right one selected and in the volume box make sure the microphone box has a tick in it or

select the voice tab

make sure that you have the right media selected also

select volume make sure the box for microphone has a tick in it

or you might have to depending on your operating system
Click start Control Pannel
click on Hardware and Sound

click on Sound
then you devices should come up ; speakers, Digital Audio, and headphones

plug your headphones in
then select headphones

at the bottom it will say set as default
select that!!

then when you disconnect your headphones it automatically switches to the speakers and when you plug them back in it automatically will switch to headphones

Hope this helps.

Find and Try reinstalling Driver for onboard audio look in device manager and see if there is an exclamation mark next to your sound hardware, also there maybe an audio out jack on your vid card that has priority over your onboard since its hd

Please clarify, Where is the Headphones connected? Front or back? if you tried it on the Front port without success, Plug in the speaker jack to the port where you did connect the Headphone and verify it's working or not. You can also try the headphone on the port where the speaker is connected.

Awaiting.

Is your headphone jack properly plugged in? If so there shouldn't be sound from speakers.

the reason for this is that the audio thru this jack is attenuated to a level where you don't loose quality and to prevent ear damage. You better try the audio out or audio monitor output jacks located in the back of the tv(if this model comes with them). you'll probably need an audio amp to get the speakers to work properly though.

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

Try changing the Windows Default Audio devices

1. Go to control Panel
2. Sounds and audio devices
3. The Audio tab
4. Then change the Sound Recording Device to Logitech Headphone INPUT
   

Hopefully this will work

you will have to uninstall your audio device, and uninstall SKYPE and re install the audio device and don't re install SKYPE, you can do this by going to add or remove programs, and remove SKYPE first and unplug u r headset and mic, and after removing skype you can reboot the computer, and sometimes the conflict is resolved, otherwise then go into your device manager in system manager and find audio devices, unistall the driver or Update the driver, and reinstall it and the reboot, that should take care of the problem.

right click my computer--> properties-->hardware-->device manager-->sound devices-->find realtek hd audio-->right click-->disable-->OK
