Question about Computers & Internet

1 Answer


Eight nights ago, Realtek AC97 was uninstalled from my pc and mywindows soundswent with it. when I reinstalled realtek, sound did notreturn. and updating the drivers did not bring it back, either. I eventried a system restore. no good; no matter what date I attemptto returnto, my pc won't accept it. a message says ''system restore wasunable torestore your computer to the date specified''(or somethinglike that). Ishould also point out that my pc is slower without sound. why is theloss of sound making my pc slow? So, to reiterate and summarize: all Idid was uninstall realtek ac97.nothing else. when it was uninstalled, Ihad no sound coming from mypc. I know my pc has sound because whenmy.pc is booted up or shutdown, I hear a 'thump' sound from thespeakers. plus, I connected thespeakers to a cd player and sound comesfrom them, but not when theyare connected to my pc(other than the thumpsound). I just wish therewere one person, at least, on this earth whoknows what the problem is.why or how did the uninstall of realtek ac97cause the lack of sound?this pc is windows based, but yet microsoftdoes not have any driversor updates for their drivers? they don't orcan't solve this problem? what gives, bill gates?

    Yes, I thought of all of that and did all of that prior to asking for assistance. I did EVERYTHING I can think of. nothing works. sound is cranked on the speakers and audio properties and media players. no mutes. like I said, I did nothing else except uninstall realtek. that's when my sound was gone. and btw, I also already updated the drivers you mentioned. so guess what? no luck. still no sound. I hear a airy sound coming from my speakers, but no music, etc.

    I don't know the model number. I assume I would have to take the CPU apart and look for it? sounds time consuming; but I don't know if I want to do that since I am afraid I might do more harm than good. I don't want to damage anything inside of it. it's frustrating to not have sound because 2 things I am unable to do are watch videos (such as youtube) and download music.

  • roalau Dec 29, 2008

    Well, I deleted all files associated with realtek. so now maybe I can use something else other than having to deal with that realtek ****. there must be another sound source/service/whatever that can be used. I doubt that realtek is the only one there is in all computers on gates must offer something. if I could sue realtek for removing my windows sounds when realtek was uninstalled, I would. I still don't understand how realtek caused my sounds to be gone just because realtek was uninstalled.

    Maybe you could also explain why my computer is slower without sound (sites take longer to load). why is it dependent upon sound?

Reinstall the newest Realtek drivers. These are the sound drivers for the sound card and you shouldn't have uninstalled them.

Alternatively, on rebooting the computer, you can press F8 and enter the BIOS and use the arrow buttons to navigate to the sound settings for the motherboard and change the motherboard sound output from PCI (sound card) to OS (onboard sound). This will mean you have to plug your speakers into the other set of audio holes inthe back of the computer and the sound will come straight from the motherboard.
Most people prefer to use the sound card though, as it is far superior, especially when using the latest Realtek or Creative drivers installed. (don't you use a creative driver... you have a RealTek card!)
So reinstall the Realtek Hd Audio driver and don't mess with it anymore :)

Good Luck!

PS Did you try playing a song and trying the different audio ports on your computer? Or checking the Volume Control to check that nothing is muted or turned down?

    Hi again,
    We'll get there, mate.. Just got to keep trying :)
    I have one more suggestion, download and install the UAA driver for your motherboard. Normally you would do this when installing a system from scratch, just after installing the Chipset driver and BEFORE the Audio driver.
    "The goal of the Universal Audio Architecture is to solve a very common
    problem in modern Microsoft Windows products, that of inconsistent
    support for audio. Due to the lack of a common system by which audio
    devices could describe their capabilities to the operating system, not
    to mention a lack of ability to control those capabilities, audio
    device manufacturers (such as Creative Labs, Realtek, Turtle Beach
    and others) have had to provide a series of control panels and custom
    interfaces to let a user control the device. This, in turn, requires
    kernel-mode drivers so that the user's actions can be communicated to
    the hardware itself."

    I can't give you a link because I don't know the motherboard model number, but just google the model number followed by UAA driver and surf a few sites till you find it.

    Good Luck with that one..

    You can find out if the audio bus (the UAA) driver is installed properly by going to the control panel and expanding system devices:

    Click on the High Definition Audio Controller, hit the Driver tab, and make sure it's working properly or Update the driver.
    Anyway, when building a system from the chipset up, we install this and THEN we install the sound card driver.
    So see if you get anywhere with that, and manage to get the UAA driver for your motherboard, install it, THEN install the RealTek driver I suggested before.
    If you get it up and running, congratulations, and don't mess with your Realtek sound card drivers again! Or until you are at least knowledgeable with such things and how they work! ;)

    Happy New Year when it comes!

Somehow lost my sound card driver

The super-cheapie models use Realtek AC97 2-channel drivers, while the multi channels use Realtex HD drivers. You can go direct to Realtek's website (google "realtek drivers" and go to their website.

Control Panel / System / hit the "hardware" tab, device manager, scroll down to "sound video and game controllers" hit the plus sign to the left, and your audio devices should be listed. The one with the yellow sign of doom is the problem device, and the name of the device is the one you want from Realtek.

Rather than let Windows search for it, I'd rather take it from Realtek, and run the install. Afterwards, burn it to a CD for use when you upgrade, or reinstall your OS.

That will happen sooner or later, so best be prepared.

best sol: go to start button ----->click RUN----->Type devmgmt.msc in Text Box -----> 

              Device Manager windows appears , click on Sound, video and game controllers(+), 
              if you see "Realtek AC97 drivers"(if they are visible...) then we can make sure that sound                     drivers are loaded in ur system, otherwise you have load it again.....


i) my best advice would be, dont mess up with installing, reinstalling, uninstalling sound drivers rather try   to format or reload your OS again(Windows XP) and then install drivers.

ii)  try to check volume on your speakers, volume in windows or system , volume in media players sometimes they may set to mute of no volume.......

iii) try to check all sound physcial connection that run from your computer to speakers, including power connections, cable connection ....or just remove and replace them(reseating...)

iv) try connecting a headset to your sound port, sometimes your subwoofers or speakers may fail.....

Thanking You

Realtek AC'97 driver

Before installing the AC97 software drivers, open System than click the Hardware tab than click Device manager. Scroll down to Sound, video & game controllers. Do you see a yellow ! point? If so than your drivers do need to be reinstalled. I could send you to Asus's site but they are a bit out dated so go here for updated drivers. The first one listed under Description will do just fine.
When you open the sound, video & game controller find AC97 & uninstall by right clicking on AC97 & uninstall. Only the AC97, leave the rest alone. Restart the PC than install the new drivers that you saved to your hard drive.
Check driver installed by opening controll panel than open Sound & Audio Device icon. Under Audio tab Realtek AC97 should be listed than click the Voice tab & the same should be listed.
Test both Audio & Mic functions. If either fail your intergrated controller could be defective. Lets hope everything works fine.
