I think i tried just about everything but iv had no luck at getting the sound back The volume control is gone and when i click start>control panel>sound and audio devices everything is greyed out and it says 'no audio device'

I have a conxant high definition 4.8.0.0 audio driver and have uninstalled it and reinstalled it from the disk that came with my laptop and still no sound.

In device manager there is a yellow exclamation mark next to conexant and microsoft kernel audio device. I'v tried a system restore but it never works. I'v tried the run>services.msc it is already started and set to auto

I have an advent 7111 laptop and windows xp media centre 2005 and im at my wits end.please help!

Oh and it happened after i installed a windows update.

Do you know which update it is? You can uninstall that update and see if that fixes the problem. If it does, then you can decide if you want to just not install that update.

It was the sp3 update and after i rebooted the volume was gone. And i uninstalled it from add/remove programs and still no sound.

Hi snnncts,

Sometimes this will work. Go to the Device Manager and delete the audio tree. Reboot and let Windows discovery new hardware and install it with a driver. If you then have the yellow mark, use the Audio CD to reinstall the drivers.

If it is still a SP3 issue, I think I have some info on removing it, will have to look it up. There have been issures with SP3 and AMD processors.

Hope this helps,

Thanks for the help but still no luck when i reinstalled the audio everything says - 'Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)'

Btw when i reboot i get a message saying 'cannot access volume control!'

And it's now sp2 but with the same error so the changes made by sp3 havent gone.

In Device Manager, is there a yellow question mark by any Audio devices?

snnncts

Theres a yellow exclamation mark next to everything in the audio tree in device manager.

No luck...

Downloaded -
Windows 2000, Windows XP/2003(32/64 bits) Driver only (ZIP file)

Clicked setup, after setup i rebooted and still no sound and everything in Sounds and Audio Devices is still greyed out and when I go to hardware the only thing there is the conexant hd audio with the same message 'The driver may be corrupted or missing code 39'

Thanks for the help though.

I'm just wondering why the realtek isnt appearing. Do i need to do anything else once i've installed it.

Hi snnncts,

Look in System Information and see if it lists any conflicts with your audio. Make sure the audio device is seen there. Expand the branch and see if all the CODECs are OK.
You can't do any repairs there, but it might point to an offending interrupt, or something.

Best regards,

All of my codecs are fine but in sound device it says there is an error with conexant high definition audio.

Also in problem devices there is a list of microsoft kernel audio devices all with the same error (code 39)

Hi snnncts,

I think the error 39 simply means Windows couldn't load a driver. You may have to download several versions of the driver, unzip them is required and place them in a folder. Then go to the Device Manager and rightclick on the audio device and pick "update driver". Select the method that will "let me pick the driver" and navigate to the folder with the drivers in it. Sequentially try the drivers until you find one that will work.

Hope this helps,
