Sound card Hi, I simply do not have sound from the speaker or through the speaker jack. It was sudden, no static or sometimes working, sometimes not. I suppose this means that I need to replace the sound card. Thanks, Alexander

No sound from my speakers, only from earphone jack


You must have some needed materials: driver and application recovery CDs and updated sound driver software.
Step 1: Check your sound card. Click "Start", than "Control Panel", and then "System" and "Hardware" and navigate to "Device Manager". Double click "Sound, Video and Game Controller". If Sound Card have been listed in this page, then you system already have sound card installed. If not, please check the enclosed information of your Lenovo IdeaPad Z500 to see if you should installed a sound card. If sound card is a must, then you should install a sound card. Note: if you have already installed sound card but not be listed in "Sound, Video and Game Controller", then go to "Other Devices" to check the list. Portable computer normally have no card sound because they have integrated sound management system.
Step 2: Take a look at all the output devices to see if they have been turned on and plugged in. The three jacks in following picture are for Microphone, input and output respectively. Check whether your output device have been put on mute or not. Check volume control setting. Go to "Start" "All Programs", "Accessories", "Entertainment", and "Volume Control" or just click speaker icon to set your volume.

What follows is the "Hardware", the "Device Manager" and "Sound", "Video" and "Game Controllers". Click on Sound device and then delete it. Click OK when they are a window prompt and say something like whether or not to continue the deletion. Delete all sound devices except Legacy Audio Drivers and the Audio Codec. Go to official website of your Lenovo IdeaPad Z500 and find out the updated sound driver for your sound card and download it. Then restart your Lenovo IdeaPad Z500 and reinstall the sound driver.

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.

Sir my delln5010 laptop internal speakers are not functioning , yesterday when i was listening to music it suddenly stops and after it was not functioning


Hi sir,
How can you say that it is the internal speaker that is defective? Have you tried another sound output, like headset or external speakers? If you have, and it works then the problem is definitely the speakers. You will need to have it serviced/replaced. If even the external speakers do not dork, then the problem is the sound card which is embedded on the motherboard. That means you will need to have the motherboard replaced.
But before anything else, try to check the sound playback if it is properly set to default. Sometimes we may have installed an application or clicked on something that changes the default output of our speakers. Check it first and hopefully it fixes it. Make sure that you have the right default sound output.

Getting static sound through speakers it only goes away when music plays but can still here it in the background could it be my sound card


it is a improper earthing of the pc (not likely) but definately a condensor leaky discharging while it self getting charged..its detected by seeing the amplifier and the condensors usually 100-1000 ufd.(electrolytic). one can see a buldge(if faulty) on the condensor(top) usually that area is flat.
leave a testimonial later.

Hellppp!


Sounds like a problem with the mainboard. Both of those jacks are attached directly to the mainboard. Anyhow, try doing a windows system restore to a day or two before the problem started. This will help to eliminate any software/config issues. If still no good, your best option is likely a PCMCIA (slot card) sound card. This will allow you to connect speakers and a microphone for probably less than 50 dollars. Let me know what happens.

Hi, I have a problem with Acer Aspire 5570. When the sound output is all fine with inbuilt speaker but when i connect to the external headset or to any desktop speaker, I dont receive sound. My device...


This is a common problem with all DJ's I know. Sometimes this is due to the fact INADVERTLY one connects powered equipments to the jack. The card is OK, but the jack gets fried. One nice solution is using USB sound cards (the ones that resembles Pen-Drives) and be in business again.

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

The speakers on my laptop do not have any sound. I can hear sound only when I plug in headphones. Is there a way to switch speakers? I have a Compag Presario v2000


You could have damaged the sensor in the 3.5 mm headphone jack so your computer does not realize that there are no headphones plugged in. If thats is the case you will have to have the sound card replaced. Another problem could be that the driver is messed up if you recently updated drivers roll back the sound cards driver or update it. Finally you can simply hook up old non usb speakers that use the headphone jack.

Dell 610 lptop - haedphone not working,


First try uninstalling the sound drivers from the device manager, then reboot. It will find and reinstall them, then check Dell's support site for updated sound drivers. If you find updated drivers you will need to use the update button for the device in the device manager. If this doesn't work, then it may be a faulty headphone jack. The jack should override the speakers when the headphones are plugged into it. If you can still hear the speakers with the headphones plugged in then the jack is faulty and needs replaced. If the jack does override the speakers or if you get some static then it could be that the jack has come loose or has a loose or broken wire. The only other thing is try a different set of headphones, sometimes laptops get picky and one set will work and yet another set may not.
