Headphone jack does not work


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.

Is my sound card damaged? My sound driver is present and i think it's working fine, sound bars are moving also when i drag the slide up and down. But, theres no sound coming from built-in speaker...


Hi,
Based on the information you have provided, it seems that the issue might be with the Audio Output Jack.
Usually some Computers have an additional Audio Jack on the CPU.
If you have such an option you can try connecting the Speakers and Headphone to that Audio Port and check.
If you do not have an additional Audio port, then it is confirmed that the issue is with Audio Output Port.
It is recommended to replace the Sound Card. You can also check with your favorite Computer Retailer, if only the Audio Output Port can be replaced.
Please let me know if you have further questions or need any assistance.

No sound out of the speaker of my lap to dv9000


hi im josh may i he lp you? try this; Sound cards range from simple built-in features to elaborate two-piece devices with physical control panels that mount into a 5 1/4-inch drive bay. The basic purpose of sound cards is to allow the user to hear sounds played by the OS and programs, along with music from audio CDs and other audio files, plus sound from DVD and other types of videos. In addition, these allow for voice communication using software such as Yahoo Messenger, AOL Instant Messenger, and Windows Messenger, along with Internet telephone calls, voice-recognition software, and other uses.
Sound Card Removal and Installation Sound cards are physically installed and removed in the same way as any other card using the same interface (PCI or ISA), except that there are likely to be analog audio cables connected to it inside the computer. On a motherboard with onboard sound, there will also be audio connectors. These connectors are for connecting analog audio to optical drives, modems, and other devices. Some of these connectors are polarized, but even if they aren't, the worst that can happen is that the right and left audio channels could be reversed. Figure 8.4 shows the audio connectors on a sound card.
0804.jpg
Figure 8.4: A sound card's audio connectors. External Sound Connections Sound cards can vary as to the number and type of external inputs and outputs. The most basic, usually found on motherboards with built-in sound, have three:
Microphone input: This is for a computer microphone, although battery- powered condenser mics usually work in these jacks.
Line input: This is for an external line source such as a cassette deck or CD player's line outputs.
Speaker/headphone output: This is a headphone-level output that can sometimes drive small, non-amplified speakers. They are usually connected to amplified speakers.
A sound card with a built-in amplifier would have full-power speaker outputs, able to drive most non-amplified speakers. More advanced cards have a whole assortment of inputs and outputs. On many cards, the icons that identify each jack are very difficult to see and interpret, especially when you are struggling just to see any part of the back of the computer. Consult the manufacturer's documentation. Figure 8.5 shows sound card jack panels.
0805.jpg
Figure 8.5: A sound card jack panels. Now look carefully at Figure 8.5. The concentric arcs represent sound waves. An arrow pointing toward the center indicates a line input, while an arrow pointing away from the center represents a line output. The microphone and speaker icons are more illustrative than are the others.
Diagnosing and Repairing Sound Problems There are a number of steps you can take to correct sound problems. First, make sure the speakers are powered, turned on, and turned up. Make sure all external connections are correct, and that the cables aren't damaged. Run System File Checker (see Chapter 11). Reinstall the sound drivers. Sometimes, you'll have to remove the device in Device Manager, shut down the computer, remove the card, restart the computer and uninstall any programs that came with the sound card, and then shut down the computer again. Then, follow the manufacturer's directions for installing the card, or just reboot and see if Windows will install it correctly. If you have any trouble with resource conflicts, which would be evidenced by instant lockups, go into the BIOS and make sure Plug and Play is enabled.
Selecting a Sound Card A basic sound card is good for most people. High-end models are good for gamers and musicians. Some people like to have surround sound with their computers, so surround sound models are common.

good luck

Built in speakers don't work.i have sound only when i plugg the headphones


Looks like there is some problem with the stereo headphone connector. As its a hardware issue, I would recommend sending it to the service center.

You may also use external speakers temporarily.

It sounds like a hardware problem, but to be sure, trying playing different kinds of files and also use a different player. For example, if you're using Itunes, try Windows Media Player or playing a sound file from the internet such as a myspace page.
