Audio not working on advent 4211c netbook. Driver shows 'unknown device on high def audio bus'

    I don't think that its that simple. I've reinstalled the drivers numerous times, and actually even reinstalled the entire os system on the computer. The drivers were included in a folder in the computer and I used them after the first installation, however it failed again. This time I reinstalled new OS and am grabbing the drivers off another site so that I can be sure the problem is not in the drivers folder that came with the system. 

    After reinstalling the OS the first time, before I even load the drivers, its quite strange. It has the 'unknown device on high def audio bus' repeated in the device manager about 12-13 times. 


    for good measure I'll try the link you sent me and reinstall the drivers, although I'm about 99% certain that will not work. Do you have any other ideas about this? 

    Thanks, 
    Robert

  • robstabile Feb 03, 2010

    The drivers are not there that's true. . . but every reinstall has the same problem. . . I cleaned the entire drive, reinstalled a different XP off a CD because I didn't want all the rubbish that comes with 'The Tech Guys' Self installed software. In order to get the proper drivers I originally took them from the original os that came installed prefabricated on the computer and copied them to an external hardrive, then reinstalled them on the new system. This failed so I took the drivers from the tech guys website, and installed them again. This failed as well (although the audio drivers installation every time went through without a hitch). Finally I took the link you gave me (thinking perhaps that your coding within the link would provide something different than the ones I installed previously from the same site) and then reinstalled the Win XP again and then reinstalled all the drivers. 

    I thought perhaps the order of the drivers may also cause a problem, for some reason I thought I remember someone speaking about there being two sets of drivers for the audio that may lead to problems when installing the drivers on this particular netbook. I was sure then in the last installation to install the drivers in the following order (and restarting the computer after each driver was installed) First-Chipset, Second-Bluetooth, Third-LAN,  Fourth-WIFI, Fifth-Card Reader, Sixth- Audio, Seventh-Graphics. 

    I followed your instructions and copied the info below. Hopefully this can help you locate the correct drivers. 
    Here is the info:

  • robstabile Feb 03, 2010

    Still no luck. I currently have both versions of the audio drivers. First I installed the one from the tech guys website you sent me to. This did not solve the problem. This version was realtek v 1.54  (even though the file is exactly the same size and thus seems to be the same as the other).I then downloaded a copy from the realtek download site you sent me to. This was version 2.41 and I installed it. No luck. I thought perhaps I needed to try some variety with these two drivers. So I uninstalled the driver and then tried to reinstall the ver. 2.41. Still didn't work. I then installed v1.54 without the uninstallation of the earlier version still it didn't work.Therefore I covered all different orders. Both with and without uninstalling the previous. 

    There is something very odd about the way this sound driver works, not sure what it is, perhaps it has something to do with a separate set of drivers for audio (something like two drivers), and perhaps to do with the order that they are installed. I know this sounds as if I just don't understand how to install the drivers, but there is something more to it (unless these are not the correct drivers, but I find that difficult to believe)

  • robstabile Feb 03, 2010

    Trying this out but a slight problem. . .there are a lot of .inf files and i'm not 100% certain which to use. They seem to have the complete .inf files for many different computers. I can't seem one that really describes this model. I attached the image for you to take a look at.Hopefully  it went through. I used the WYSIWYG editor here to upload it (although I dont see the file attchment anywher) Keep in mind this is from realtek. The techguys link only gives an .exe file which I am not sure how to work with.

    I can see the file did not sent . . . to large. . unfortunately I am print screening and have nothing on this computer but paint.. . . hard time cutting the file. I'll type in the folder by hand. .

    Ok I am looking for a bit more direct way to handle my situation than just installing and uninstalling over 30 .inf files to see if a driver will work.

    I have a advent 4211c computer that has problems with the audio driver. I have reinstalled an OS 3 times in the past 3 days to try to solve this problem. I used all the drivers provided for by 'thetechguys' in order to try to get the audio to work. Every other driver worked fine which I install although the audio still does not work

    I also downloaded the drivers from realtek to try to install them instead of the techguys audio, although this failed as well. The expert I worked with suggested I install the drivers directly by using the .inf file. Upon checking the drivers .inf files I have found over 30 files in the download (from realtek) although no real way to determine which .inf file is correct for my computer . . if in fact any of them are.

    I'm wondering if there is a more direct way to handle this problem then attempting to install and uninstall these .inf files over 30 times, or if someone has had any direct experience with this issue on this type of netbook.

  • robstabile Feb 04, 2010

    I did that at first and received a 'the hardware was not installed because the wizard could not find the necessary files'. 


    Perhaps that is the wrong realtek driver for this computer. . . or am I missing something? 

  • robstabile Feb 04, 2010

    After all this I'm at the point where I just don't have the drivers necessary to install them and I don't know where to get them. The original installation folder that came with the computer (i saved it on an external) is only an .exe file. The only zip I downloaded from realtek doesn't have the proper .inf file on it. Any clue how else to get the proper driver? 


  • robstabile Feb 04, 2010

    thanks trying that out right now. . 


  • robstabile Feb 04, 2010

    yes its paid, yes I paid, and no luck yet. I sent out a support request with them to see if they will be able to handle this hopefully so. I'll give them a little time and see how it goes. 

  • robstabile Feb 05, 2010

    do you think this could have anything to do with it? The Advent is really just a msi wind u100 and i found a thread talking about this problem, Your thoughts on this?

    For the second comment the drivers at softpedia that is the kb update there. . question is though cannot get it to work. They offer these drivers

    Microsoft UAA Function Driver for High Definition Audio - Adi 1983
    Microsoft UAA Function Driver for High Definition Audio - Adi 1986
    Microsoft UAA Function Driver for High Definition Audio - CMedia 9880
    Microsoft UAA Function Driver for High Definition Audio - Conexant Waikiki

    Microsoft UAA Function Driver for High Definition Audio - Sigmatel 9772
    Realtek Content Creation Bay
    Realtek High Definition Audio



    although mine is a Realtek 888 integrated soundcard. Was wondering if you knew what the 880/860 or 260, 261 all of that mean in realtion to my computer. Thansk

  • robstabile Feb 05, 2010

    Ok there is are some issues. The computer is a netbook and never came with a cd for it has no optical drive. Therefore the orginal drivers were installed on the computer and held there. The audio did work for some time then one day it vanished. The computer had a reinstall option on it, although when i did this . . same problem. I was also tired of the version of windows that came with the computer for it had a number of terrible options (techguys) that I no longer wanted on the computer.



    Since i had deleted my entire hard drive I decided to borrow an optical drive and install a fresh vesion of win xp sp3 for the computer. I stored all the original drivers in a folder. I then installed xp sp3 to the computer and then installed the drivers. To my chagrin same issue.



    The driver installation goes through the motions but never installs. I tried to install it manually with the original driver, but the installation wizard never finds the proper file. There are over 30+ inf files in the folder, and not sure whatelse to do with that.



    I dug further and found that some issues are out there when installing these HD Audio Drivers from Realtek to win xp sp3. There seems to be some flaw as mentioned in this thread. . .



    http://social.technet.microsoft.com/foru...



    I tried to manually install the kb hotfix but alas there is no realtek ACL 888 .inf file on it . . only 880 and other versions. So tried it anyway with no luck . . . not sure if that thread is even applicapable to my situation. Thing is nothing seems to work when installing this driver. It did work at one point. . but that was a long time ago. I'm just sick and tired of it not working and have devoted over 40 hours now trying to fix this problem. Any suggestions are welcome.

Try this, its only a suggestion being as you have tryed everything else. Goto device manager find the driver in there for your sound card right click and goto properties, goto resouces, check to see if it has conflicts and check the irq it should i beleve on ...00016( 22) there may be a conflict there. And maybe somthing more simple like a mute setting.

    I really hope that they can sort this for you, i havent herd of sound drivers given somone this much trouble before, hopfully because its a paid site they will get to the bottom of it for you, i am sorry i couldnt find a free one for you, but if it was free you would have proberly downloaded the same driver you have already got. I hope you get this issue resolved, and post back and tell me the outcome. thanks.jim.

  • jimnuggats Feb 05, 2010

    Have you tried updating the bus driver in the device manager, somtimes instead of trying to download the correct software doing an update through device manager does the trick, goto device manager and click update driver on the bus driver thats missing, use the internet option to download the driver, it takes a few minutes so be patient, i had i realtek sound card myself a few years ago i found the same type of problem with the audio bus driver even though the driver was installed, it wouldnt pick up the bus driver. if you have already tryed this then you could try driverguide.com you register for free and hopfully they will have the drivers you need.

The audio driver needs to be reinstalled. If you have the disc that came with the computer, it will be on there. If not, you can go to Advents website, go to support, and download the latest audio driver for your computer. Going to their website is probably faster and easier than trying to locate the correct driver on the disc. Hope this helps...

Hello,

When did this problem start?
Has the sound card been working before?
It looks like your sound drivers are not recornising your sound card, as a result there is no sound on your computer.

If you installed the drivers and they were working before, then the drivers must be corrupted.
To solve this, you need to reinstall the audio drivers.

If the sound has never worked at all, you must have installed the wrong audio drivers for the sound.
You should install the right drivers, which match the current Operating System you are using in your computer.
If you are using Windows XP, then install Windows XP drivers, if it is Vista, then install audio drivers for Windows Vista.

These drivers must be available in the Drivers CD that came with your computer, use the CD to install the drivers.

Let me know if you require more assistance regarding this problem.
Thank you for using Fixya,
Kenneth.

    Fine, I've fixed over 300 laptops/desktops in the past year not counting the advice I post here, now, you tell me what is it then, the unknown devices are devices or parts of a device or software that has not had a driver installed.

    why don't you tell me all the pnp id's from the devices that have a problem, to do that, hold down the windows key and press R, write msinfo32 and click ok.

    on the right side of the window find +components and open that up, under there find problem devices and open that.

    Copy and paste me all the lines from that window, and I'll get you the drivers that are missing.




  • Ekse Feb 03, 2010

    what folder are you talking about? if you did a fresh install from a windows setup cd, you won't have such a folder. Most likely the folder does not contain your drivers, and you are missing the drivers from your laptop.

    you are missing realtek hd audio drivers.
    http://www.realtek.com/downloads/

    take the "High Definition Audio Codecs (Software)"

  • Ekse Feb 03, 2010

    the tech guys link I gave earlier has the same realtek drivers, take both anyway. you may have to direct the driver wizard into the driver folder - to the inf file to get them to install, from the download of the tech guys website, if the realtek link doesn't work.

  • Ekse Feb 03, 2010

    install the drivers for the card manually, do not use the setup utility

    http://www.youtube.com/watch?v=MFS7DUH7U...



    Please jump to 1 minute and 50 seconds 1:50, anything before that is irrelevant.


    Basically

    Right click on my computer on your desktop or in your start menu Select Manage
    on the left side of the window, click on device manager.

    now on the right side you need to find the unknown devices or any device that hasn't had its driver installed.

    right click on the device and select update driver, don't search online, take the advanced method of installing, then select I will select the driver to install then click on have disk and point it to the folder where you extracted the drivers to, more spesifically, where the inf file is in.

    the wizard will find the driver and install it.


  • Ekse Feb 03, 2010

    Okay, you can try the search method - point the wizard into that directory, in the wizard on the screen where you selected Let me select the driver, you could instead use the search option above.

    or you can try each of the inf files blindly.

  • Ekse Feb 04, 2010

    Sorry you got it wrong, use the search method and it automatically looks them all over, the inf file - wizard will tell you if a driver for the hardware was found or not.

My realtek audio driver is not getting installed. everytime i am trying...at the end its showing a message install failure. pls help..


Hi,

1. Make sure your installation windows XP has been updated to service pack 1 or service pack 2 before continuing. Right-click on “My computer” icon on desktop. Select “Properties\ General. If your system does not include service pack, please update from Microsoft's official website. Connect to internet and launch “Internet Explorer”, click “Tools” on the tool bar and select “Windows Update”.

2. Make sure that the “Microsoft UAA Bus Driver for High Definition Audio” exists in “Device manager\ System devices”. Right-click the “My computer” icon on your desktop. Select “Properties\ Hardware\ Device Manager. If the “UAA Bus Driver” does not exist, install it from the download link below to install on your system (for some reason, Microsoft does not post a download link for this update anywhere on their site). Launch the sp32646 file you have downloaded from HP's website (URL below) and reboot computer after the installation.

3. If the “Microsoft UAA Bus Driver for High Definition Audio” is working properly, there may be an “Audio Device on High Definition Audio Bus” or "Realtek High Definition Audio" behind “Sound, video and game controllers” or an “Unknown device” behind “Other devices”. Please disable any of these devices. You can skip this step if device mentioned earlier does not exist in “Device Manager”.

4. Disable the “Microsoft UAA Bus Driver for High Definition Audio” under "System Devices".

5. After that, uninstall the “Microsoft UAA Bus Driver for High Definition Audio" by right-clicking the device and select uninstall.

6. When finish with the above steps, click the “Scan for hardware changes” button by clicking on the computer icon with magnifying glass toward the top of the page. When the “Found new hardware wizard” is displayed, don't click the “Next” button. Instead, cancel the installation by clicking cancel.

7. You can now install the audio driver from the driver file that you have downloaded from the internet or from your driver CD/ DVD.

Thanks.

That doesnt have an internal cd/DVD drive because it's a netbook. You need to buy an external drive and plug it in to the netbook to use CD's or DVD's
