Cant get the audio working on my PC

October 23, 2006 at 00:22:06
Specs: Windows XP, Athlon 2600+ / 1GB RAM
I can’t get the sound on my PC to work. It used to work just fine, then, one day, it stopped working, and I haven’t been able to get it working since.

My system is Windows XP Pro SP2.
My motherboard is ASUS A7N266.
I recently purchased a new PCI sound card (Creative Sound Blaster 128 – CT4810).

I know that it’s not a problem with wiring or my speakers. I have tested the cables and speakers with my laptop and they work fine.

It seems like the audio “device” is just simply not recognized. From the Control Panel, when I go to “Sounds and Audio Devices”, I see the message: “No Audio Devices”. So, there’s the problem. Of course, the issue is that I DO indeed have an audio device, so this statement is wrong.

I was originally using the onboard sound card with my motherboard. I never had any problems with it. After the sound disappeared, I tried the following:

I uninstalled and reinstalled the latest driver for the motherboard and sound card – same problem. I disabled and then enabled the device – same problem. I checked the IRQs, looking for a conflict – there wasn’t one. Looking in the device manager, there were no yellow exclamation points, and all of the devices listed under “Sound, Video, and Game Controllers” had properties which all said “This device is working properly”. I even ran the Windows Audio Troubleshooter – it was useless and didn’t get me anywhere.

Thinking it was a problem with my motherboard’s audio hardware, I went out and bought a PCI audio card (see above). According to some docs I read on the web, I needed to disable my onboard audio through BIOS in order to get the PCI card to work. I did this. Next I installed the driver for the sound card. Everything seemed to go fine.

Looking in the device manager currently, all items under the “Sound, Video, and Game Controllers” section are ok and have no yellow exclamation points (and have properties which say “This device is working properly”) except the “Game Port for Creative” item. Big deal, I figure…

But now, I still have the same things as before.: The audio “device” is just not recognized. Under “Sounds and Audio Devices”, I see the message: “No Audio Devices”.

As I mentioned before, my audio used to work just fine. For years. Then, I used my computer one day and the audio was completely gone! Argh! This is driving me nuts! Please HELP!

1. Can anyone fathom what could possibly be going on?

2. Can anyone give me some suggestions on how I can diagnose the problem, or steps I can take to correct the problem?

Have you tried a different slot?
"This device is working properly”) except the “Game Port for Creative”"
I would go to device manager , right click and uninstall the sound card then reboot and reinstall your software (drivers)
The software if correct for the card should have the gameport drivers also

" Please Post back to let us know if we helped "

Have you installed any new devices that use IRQ's such as a card in a slot since the sound last worked? If so you may be experiencing an IRQ conflict that prevents the sound card from getting an IRQ it can use. If you did add a card, try removing it to see if your sound comes back.

If your computer and and everything connected to it connected to something that protects them from power surges and spikes?

No, I haven't tried a different slot. But, I can't imagine how it would help. I experienced the same problem when I was using the on-board audio card. Since I'm seeing the same thing with the PCI audio card, after successful installation of the driver, it sounds to me like it's definitely NOT a problem with the PCI card. Wouldn't you agree? But for lack of anything else to try, I guess I'll try it anyway.

No, no new devices were installed that might cause a IRQ problem. The onboard sound was working, then the next day it wasn't.

And yes, I do have spike/surge protection on this PC.

An interesting suggestion. I restored by registry settings for audio, but to no avail. After a reboot and a re-install of the audio driver, I have the same problem again.

Thanks for the suggestions guys, but none have helped yet. Any others?

Is everything connected to the computer protected, including all the AC cords and power packs for things that plug into the computer, and your phone line and/or cable that connect you to the internet and/or so that you can fax?
Have there been any recent power outages or lightning in your area since the sound last worked?.
Does your spike/surge protector have an led that indicates it is still protecting (if it doesn't it's an el-cheapo) - if so, is it still lit?

A defective power supply that isn't putting out some of the proper voltages can cause some devices to not work. Check your PS.

Some of the files on your Windows installation could be damaged.
You could try checking your hard drive, and/or running an XP Repair Setup.

UPDATE: Based on a good suggestions from another forum, I tried to perform a Windows XP Repair installation from the XP Setup CD. Unfortunately, this failed. However, I DID clone my disk and re-install XP onto that hard drive. Guess what? The audio worked fine. So! That tells me that the problem is most likely with the Windows XP Audio sub-system (i.e. Windows Audio Service, DLLs, etc.).

So, now what I need help with is figuring out how to re-install the Windows audio "sub-system". Does anyone know how I can do this? Does anyone have a list of DLLs and other files I'd need to extract from the XP setup CD (and where to find them) in order to completely reset XP's audio?

Any help in this matter would be greatly appreciated!

"I tried to perform a Windows XP Repair installation from the XP Setup CD. Unfortunately, this failed."

What do mean by "Unfortunately, this failed."??

If you mean it went all the way through but didn't cure your problem, it can't fix all problems.
If you mean an XP Repair SETUP (I also suggested that in response 5) where it takes almost as long as a regular Setup, that only works if what was wrong can be fixed by replacing corrupted files or providing files that were missing that were on the original XP CD, or by correcting settings related to those files.

You could try running: sfc /scannow
(system file checker) - that will replace any files that were missing, but it may not help either if the ones you need were not on the XP CD, and if you ran an XP Repair Setup all the way through, they're probably already been replaced.
Insert the XP CD in a CD drive.
Start - Run - type: cmd (press Enter)
type: sfc /scannow

Something corrupted some of the files on the hard drive. It could have been the drive itself. See response 2 in this for how to diagnose your hard drive:

Also see response 5 for other things that can cause data problems - no spike/surge protection, or a bad PS.

As for the CT4810 drivers, if it came with a CD, un-install the drivers in Add and Remove Programs, re-install the drivers from that. If it didn't, CT4810 is one of the Creative PCI 128 family of cards. There are several different chipsets used in that family, and the same drivers cannot be used for all of them. From previous experience I know XP has drivers built in for some of the PCI 128 family but not all of them.
If the drivers were not included with the card, and if Windows did not install the right built in drivers, see response 1 in this for the correct ones:

Well, I did finally manage to get my sound working again. I used the Windows XP Repair Installation tool, but I ran into some problems with it:

I first cloned my disk and then tried the XP repair installation on the cloned drive. I think there were some errors or indexes on the drive that were out of whack that prevented the XP setup from properly recognizing the XP installation on the drive. That's what threw me off to begin with.

Later, I tried the XP Repair Installation on my actual drive, and similarly the setup couldn't detect the XP installation. The problem this time, however, was that my disk is formatted with a single 200GB partition. My Windows XP setup CD is one of the old ones that didn't recognize drives larger than 137GB. To solve this, I had to borrow a more recent XP Setup CD.

Anyway, long story short, my sound now works! The repair installation somehow knocked out my wireless adapter, which I had to re-install, but aside from that, everything else seems to look good. And best of all, my sound now works! Hooray!

For anyone curious, this is link I used for help in using the XP repair installtion tool:

I'm glad to hear you can now hear your sound, but....

An Xp Repair "installation" or "install" is an mis-used label of the procedure you used - unforunately it's a common one. The proper label is an XP Repair SETUP procedure, of your already existing XP installation - it's the same thing as a regular SETUP procedure, except it preserves what is already on the Windows partition rather than starting over from scratch. All your Windows settings and the stuff added after Windows was initially loaded such as the registry entries and files added by program installs are left as they already are, unless they are corrupted or files are missing and Windows can fix that because the needed files are on the original Windows CD.

The link at the end of your last post is not about some magic tool he discovered that no one knows about - it merely tells you how to use the Repair Setup procedure already built into XP.
If you had looked at the last link I pointed you to in response 5, that points you to a similar link about the same procedure.

As far as the XP installation you had on the drive where the sound wasn't working, if you have an older XP CD that doesn't have at least SP1 updates included on it so that it already supports partitions larger than 137gb manufacturer's size (= 128gb in Windows), one way to get around that is what you did, use a newer XP CD for the Repair SETUP, but it must be of the same version (e.g. Home or Pro) or the Product Key for your original XP CD may not work with it (if you use the key for the newer CD you are using it illegally and will have problems because of that - if not at first, you will later). A better alternative is the link you pointed to at the end of the last post has a link near the beginning that tells you how to "slipstream" your older XP CD data with newer updates such as the SP2 ones onto a burned CD, and then use that instead of your original CD, using your original Product Key.
