Audio Drivers not detected.

I recently reformatted and reinstalled windows xp, but now even after I enable windows audio service, enable onboard soundcard, and install drivers I get a "No Audio device detected' In the device manager,my onboard sound card is listed as Audio Device on High Definition Audio Bus with a yellow question mark next to it. On its properties it says it is not configured correctly. I have a Asrock k10n78m motherboard. Anyone know how to fix this?

Install the audio driver from the motherboard installation CD or go online to the motherboard product page and download and install the latest sound driver from there.

Maybe the onboard sound chip is defective and no longer operable. If you have the correct audio driver installed, try deleting the audio device with the yellow ! in Device manager. When the machine restarts perhaps the driver will install on restart. Otherwise, when you did the reformat and reinstallation, some of the files may have been corrupted/omitted. You could run a chkdsk and see if that finds anything.

Didn't work, tried both.

Ok, will try installing in safe mode, its late here, so probably going to be going to bed after.

I would try instaling the sound driver on the MB CD.

Do yu have any other devices like a PCI device tv tuner card or a usb/pci wireless adapter installed on the machine? There could be a conflict with another device on the system.

In Control Panel what happens when you click and open Sound? Also, is there a Realtek sound control panel installed on the Start Menu? How about in Control Panel, any Realtek software control panel for sound?

I hate to say try a repair install. But if there is a problem in the registry with sound device, this would repair any problem.

perhaps try agin to 'uninstall' the realtek sound device in Device manager then reboot the system and if realtek sound can pick up the driver and install it.

I have tried uninstalling the device, and have downloaded those drivers, will download them again and reinstall though. Also there is no realtek option in control panel, when my sound works there should be a red speaker icon, and "no audio device " when i click sounds and audio.

Be sure to install SP3. Again, for some reason the driver is not installing like it would normally. Could be the result of a 'bad' sound chip. But the sound worked before the reinstallation of XP. Maybe something in the registry is corrupted during the reinstallation of the OS. You may try running CCcleaner's registry cleaner. A Repair Install of the OS is another option.

Sorry, was busy. I have an radeon hd 4650 with the latest drivers installed. Downloading that patch though.

Okay, and that nvidia onboard patch said I do not have the right hardware.

I think I would uninstall that realtek audio driver then try and reinstall the original realtek driver from the MB CD. In fact, you might install driver sweeper and uninstall any realtek audio drivers on the system. That would hopefully clean up any registry entrys too.

Well, did Driversweep, deleted everything to do with realtek and then reinstalled the drivers from the cd. Now Its back to having a ? next to it in device manager.

It failed to install, going to try and reinstall.

Downloaded the required files and installed but it still cannot run for some reason.

I'm setting at a system that the LAN controller does not show at all in Device manager. It's a refurbished unit I kept because everything else on the board workd fine and it's out of production. I installed a $9 LAN card and it works fine. 'Scuse me while I reboot and enable LAN in BIOS for the umpteenth time. I have to check with a magnifying glass for phsical damage to the plug when I get time. Been messing with the missing onboard LAN controller for some time now. It's all magic by now LOL.

Your welcome. I wish we could have solved the problem.

I forgot, if you do not have have MS's .NET, ATI drivers won't work. Installing .NET will be an option when you load the HD4650 Installation CD.

ATI's HD audio channels the audio through the HDMI cable to the TV/Monitor and its speakers. The Realtek HD can run through analog speakers using the colored jacks on the rear of the motherboard, or with an optical cable using the S/PDIF jack on the rear of the motherboard. What speakers and jack/cable are you using to hear your audio?

That is the analog line-out for a 2 or 2.1 speaker configuration. Really dumb questions: Are the speakers connected to each other properly, and powered-on?

More dumb questions: Volume control on the speakers turned up? Volume control in the tray turned up (not muted)?

You know I'm reaching here. You should have sound.
