Would like to use audio output jack for headphones, how do you get it to work?

The speaker cutout feature whenever the headphone jack is connected is a hard-wired feature of the headphone connector, and cannot normally be bypassed without further electronic circuitry and the associated surgery to install a custom modification in the TV. In order to keep the TV speakers on while using the sound elsewhere, you will have to take the audio output from the IR Audio port, if there is one.

Go in to the "applications>utilities" folder. Run the "Audio/MIDI Setup" program. Insure the audio out is actually going to the headphone out.

The headphone jack on the computer connects to the sound card, a hardware device that controls audio input and output on the PC. The card contains a digital-to-analog converter that converts analog audio into digital signals and visa-versa. The performance of the headphone jack, therefore, depends on how well the sound card functions; if the card doesn't work, then the headphones connected to the PC won't output sound. Reconfiguring the audio settings will often fix problems with audio output on the headphone jack, but if the former fails to resolve the issue, replacing the sound card in its entirety is sometimes the only means of repair.
Click "Start." Enter "sound" into the search box. Select "Sound" from beneath Control Panel. Double-click "Headphones." If no "Headphones" option is available, double-click "Speakers." Click "Properties" on the General tab. Check the Device Status field for errors. Look up the message on Microsoft Support for more assistance, if applicable. Close the window if the Device Status field reads "This Device Is Working Properly." Go to the "Levels" tab. Click the speaker button to unmute the volume if the icon contains a red circle-backslash symbol. Drag the top slider to the right to increase the headphone volume. Go to the "Enhancements" tab. Check "Disable all Sound Effects." Go to Applications, and then clear "Allow Applications to Take Exclusive Control of This Device." Click "OK" to close Headphones Properties or Speakers Properties. Test the audio. If the headphones fail to output sound, unplug the headphones from the computer. Reconnect the headphones to the PC. Headphone jacks are color-coded lime green on most PCs. Look for the headphones symbol if the jacks are not color-coded. Plug the headphones into the line-out port on the back of the computer if the headphone jack on the front of the PC fails to work, or visa-versa. Test the headphones. If headphones still won't emit sound, the sound card most likely requires replacement. b> Replacing the Sound Card b> Shut down the computer. Remove the power cord from the back of the PC. Disconnect the keyboard, mouse, monitor and all other peripheral devices. Loosen the screws found on the back of the case, then slide the cover panel off of the case. Touch the chassis to protect the hardware from electrostatic discharge, or ESD. Set the computer on its side. Locate the sound card found on the opposite of the audio jacks and loosen the screw that secures the card to the computer. If no expansion card is located opposite the jacks, the computer uses an integrated sound card which can't be removed. Remove the new audio card from its protective packaging. Line up the card with an available expansion slot on the motherboard, then push the card down into the slot to install the new audio jacks. Screw the card to the computer case. Reassemble the computer. Turn on the PC. Boot in to Windows and insert the CD that came with the new expansion card. Follow the onscreen instructions to install the sound card software to the computer. Plug the headphones into the new line-out jack. Hope this helps.

you may have to set your audio input/output device back to the jack

Check you USER MANUAL to make sure it is actually a headphone OUTPUT jack and not a digital INPUT jack.

If your tv does not have a headphone output jack you can always get an adapter that plugs into the red and white AUDIO OUT jacks in the back.

If you want to turn off your tv's speakers, go to the MENU.
Then go to AUDIO then select SPEAKERS OFF.

Good luck and please post back with how you make out.

I have a Panasonic viera 32in lcd hd tv. I'm trying to hook up headphones but there's is no apparent audio output jacks. But there's is only one digtal output jack! is this the jack ? and if it is, what cables do I need to make the headphones work? or am I forced into by an amplifier

Try the Audio 1 rear. With the headphones plugged in on some T.V.s the headphone jack unfortunately disconnects the audio from the other outputs. Try looking in the documentation to see if you can change this in the T.V.s menu as some allow you to use both for hearing impaired people. Hope this helps.,

put the black pin of ur headphone in mic jack of laptop(mostly red color) and green pin of ur headphone in output audio (mostly green).

hope this helps u.. cheers Rajeish

if your tv has an audio output other than the hphone jack. either an optical or composite audio output.

Plugging headphones into the computer will disable sound output from the sound card by design.
