No sounds device detected.

Asus A8n-sli deluxe motherboard
August 11, 2009 at 09:30:18
Specs: Windows XP Pro

Recently, I had to reinstall windows on a new hard drive. After installing all of my drivers, (and I've done this a hundred times, I know how to get the drivers for my motherboard), windows updates (I can't count how many times something bad happened to my computer because of windows updates), etc. and I discovered the computer will not detect a sound device.

I've reinstalled the usual drivers from my motherboard's cd and their website, I've tried updating the BIOS, I even reset the battery. But in no way will my onboard audio device be detected.

I do not have any exclamation points or any signs of missing or corrupt drivers, however I did notice a lot of my drivers have (2) instances and some of them say Unknown location. Even though I keep installing the correct drivers, they don't seem to show up in the device manager (even hidden devices.)

Maybe the onboard sound card died? I don't know but there are two of them on the board and neither of them work.

The windows audio service is started, I've restarted it many times. The device is enabled in the BIOS. The drivers won't update any further and if I wanted to install ones such as "Audio Codecs", or "Legacy Drivers", I can't because there is no Uninstall option. The devices in the list:
Audio Codecs
Audio Codecs }these two are unknown location and do not have an uninstall option.
Legacy Audio Drivers
Legacy Audio Drivers }these two are unknown location and do not have an uninstall option.
Legacy Video Capture Devices }no uninstall option.
Media Control Devices }no uninstall option.
MPU-401 Compatible MIDI Device }this comes back when I uninstall.
Standard Game Port
Video Codecs

Hidden Devices: (also come back after they're uninstalled)
Microsoft Kernel System Audio Device
Microsoft WINMM WDM Audio Compatibility Driver

Note: The drivers I've been installing (including realtek) do not appear in the list. I would think the problem is that I cannot uninstall the 2 instances of the unknown drivers. There are no other devices listed as 'other' or 'unknown'.

Windows XP Pro SP2 32bit
AMD Athlon x64 3500+

Hopefully it's enough info for someone to help me out. Everywhere I search, the only help I get is "be sure you installed the correct drivers" but that doesn't seem to be the problem here.
Also I had to go buy new speakers to find out that they didn't work, so my old speakers should be fine after all.

And stupid me I never have system restore enabled.

"I've done this a hundred times"

On the same system? lol

"I've tried updating the BIOS, I even reset the battery"


"But in no way will my onboard audio device be detected"

All the drivers you listed (Audio Codecs, Legacy Audio Drivers, MPU-401 Compatible MIDI Device, etc) are generic. Did you manually configure the BIOS settings after removing the battery? Did you confrim that the onboard audio is enabled?

The onboard sound must be enabled in the mboard's bios Setup. It is by default, and when you load bios defaults, or when clear the cmos and move the jumper back, or when you remove the cmos battery for a short while then replace it.

You must plug in amplified speakers into most onboard sound, and the speakers must be powered on, and the volume on the speakers must be set high enough for you to hear something . If you have a single pair if speakers, the 1/8" jack you plug them into is usually green. If you have more than two speakers, you may need to use a program supplied with the sound drivers to set up the use of other jacks for some of the speakers, or if that program is already installed, something may pop up and ask you what you are connecting to other than the green jack when you plug something into the jack. Sometimes an icon for that setting program is in Control Panel after you install the sound software.

You should always install the main chipset drivers before you install other drivers, otherwise the software for other devices may not install, properly.

Whenever you load Windows from a regular Windows CD (or DVD) from scratch, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP or PCI-E, ACPI, USB 2.0 if it has it, and hard drive controller support. If you have a generic system and have the CD that came with the mboard, all the necessary drivers are on it. If you load drivers from the web, brand name system builders and mboard makers often DO NOT have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them.

When an installation of drivers and associated programs (the sound drivers download usually includes associated programs) fails to yield you sound, if you can't find any reason for that, you must un-install any listing for that in Add/Remove Programs BEFORE you attempt to install that or other sound driver related software. If you do not do that, the previously installed software is likely to interfere with the proper installaion of the software you're installing, especially if it's made by the same chipset maker.
If there is anything unknown to do with the sound in Device Manager after un-installing entries in Add/Remove programs and re-booting, Remove those entries in Device Manager before installing the sound software. If they appear again after rebooting, you may need to Remove them again, and NOT reboot, install the sound software, then reboot.

DO NOT install the sound drivers while booting the computer. (This also applies to lots of other devices.)
When you boot the computer and Windows detects the sound device, and you have it search for drivers and it doesn't find any, and it asks you to point to the location of drivers, if you DO load thedrivers that way, in most cases at least somefeatures of your sound will probably not work properly, if you get any soundat all. CANCEL that, and let thedesktop screen load, then run the proper installotion download or sound software installation from your mboard CD.

Sound chipset makers make lots of versions of sound chipsets. You must install the right drivers and associated software for whatever chipset. The sound software that came with the mboard on it's CD, the sound software for your mboard model, and the sound software that can be downloaded from the chipset makers web site for your specific chipset model is the correct version, but a version you get randomly on the web may not work properly, or at all.

NOTE that some mboard models have TWO possible onboard sound chipsets - e.g. a simpler AC97 compatible codec one, which usually has only 3 1/8" jacks, or an optional more sophisticated sound chipset, which usually has more than three 1/8" jacks. A mboard CD or the downloads for your model on a mboard manufacturer's web site may have software for both types. See your mboard manual. Check the model numbers of the sound chipset on your mboard.

If you have a sound card (in a slot) installled as well as having the onboard sound, Windows supports you installing support for more than one sound chipset, but only one can be used by Windows at any one time. Whatever software you installed last for whatever sound chipset becomes the default sound device used.
You can change the default sound device in Control Panel - Sounds and Audio Devices - Audio

Nothing is unnecessary when
a. I've tried everything else before doing it.
b. It won't hurt as resetting the battery solves a lot of problems anyway.

Well, it didn't turn it off in the BIOS because it's enabled by default (on board device.) But yes, I checked as said in first post, the whole reason I post all the information is so I'm not asked about it.

The only thing I can think of is the drivers that I can't uninstall would be interfering with the ones I need but I have no idea how to get rid of them to find out.

In the beginning I had no choice to install the chipset drivers first, the ASUS disc does them both one after the other.
Like I said I had to try a new set of speakers.
I don't have any other sound card installed.

The realtek driver I use, and always have used, does go into ADD/REMOVE programs list but I have tried uninstalling and reinstalling from sources other than the asus disc.

No, wrong, you can't change the audio options when it doesn't detect a device (refer to title), everything is grayed out.

"... I don't have any other sound card installed..."

The term CARD is frequently mis-used. Anything built into the mboard IS NOT A CARD!

"....the drivers that I can't uninstall ..."

If you can't uninstall existing listings for sound related stuff in Add/Remove Programs, many software installations these days use the Windows Installer. Search the Microsoft web site for "Windows Installer Cleanup Utility" with the quotes, download it, install it, run it, and have it remove anything to do with the sound entries.
If it's listed, and you remove it, that will at least prevent the listed software from running, and probably prevent it from interfering with a new sound software installtion - it may also remove all the files and registry entries that were installed from the computer. I think what it does is examine the *.inf file for the installation and uses that to determine what to remove.

NOTE that you can't un-install some things listed in Add/Remove Programs in Safe mode.
