If you have Windows xp and service pack 3 and are experiencing difficulties with having no sound after a fresh installation,try this,it works
1) Open Regedit and go to :
2) Double-click CDSVersion and change it to 200, then restart your system.
100 (hex) means its sp1
200 (hex) means its sp2
300 (hex) means its sp3
3) Install kb888111xp2.exe (Microsoft UAA Patch which should be available from your Audio driver folder)
4) Install audio driver
5) Change CSDVersion back to 300 (remember this or else you system will think it's still SP2 and many SP2 updates may reemerge in your Windows Update, that's my logical guess anyway :mrgreen: )
6) Restart your system
When your computer has a conflict between SP3 and Realtek HD audio driver, right-click My Computer, select Properties, click Hardware tab and click Device Manager, double-click to extent Sound, video and game controllers, you will see there is a black exclamation mark in a yellow circle beside Realtek High Definition Audio. Try to reinstall drivers several times, but fail.
This problem would only possibly happen to Realtek High Definition audio users, and Realtek ac97 audio users would never come across such an issue. You can troubleshoot this conflict by modifying SP3 to SP2, specific instructions as follows:
Step 1 Click Start and then select run.
Step 2 Type "regedit" to open Registry Editor, under HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Windows, find out the DWORD value CSDVerision.
If the hex value is 100, the algorism value is 256, this system version is Service Pack 1 (SP1); if hex value is 200, algorism value is 512, this system version is Service Pack 2 (SP2); if hex value is 300, algorism value is 768, this system version is Service Pack 3 (SP3).
Step 3 Now you need to change the hex value to 200 and restart your computer, thereby the system version would roll to SP2.
Step 4 Now your version is sp2.Reinstall the driver.
Finally the conflict between SP3 and your Realtek HD audio
How I solved Realtek High Definition Audio driver problem.
I have Acer Aspire 5720z. Recently I downgraded my Windows Vista to Windows XP Professional SP3.
There was no sound. As you may experience it yourself, I had problems installing Realtek High Definition Audio driver. After reading forums and trying things for 8 hours (with breaks) I did the following, which WORKED:
1. Install Windows XP SP2 (format the disk with XP SP3 in the beginning of installing XP SP2)
2. I tried to install the Realtek HD Audio driver for XP taken from here http://www.realtek.com.tw/... I got ‘install realtek hd audio driver failure …227’
3. Uninstall Realtek from the 'Add or Remove Programs'.
4. Disable the Microsoft UAA Bus driver for Hihg Definition Audio (In the Device Manager, System Devices)
5. Uninstall the Microsoft UAA Bus driver for Hihg Definition Audio (same place)
6. Restart the computer.
7. Install the Microsoft UAA Bus Driver for Hihg Definition Audio taken from http://drivers.softpedia.com/... 8. Restart the computer.
9. After the restart Windows says 'found new hardware' - HDAUDIO Soft Data Fax Modem with SmartCP #2.
10. Unpack kb888111xpsp2 (taken from motherboard_driver_audio_realtek_azalia file downloaded in step 7) into a specific folder.
11. Direct 'Found New Hardware' wizard to the folder where kb888111xpsp2 is unpacked. It asked me for the Driver CD. The driver for the new hardware is installed (I don’t know from where: either from the folder or from the CD, but don’t care much now)
12. Check the sound - IT WORKS!!!
13. Install SP3. Check the sound - IT WORKS!!!
1. One of the K-lite codecs was installed at some step.
2. At the end I was not asked for the Realtek HD Audio driver. So Windows used the driver either from step 2 of the driver from the Driver CD.
3. kb888111xpsp2.exe was actually clicked somewhere
4. Possibly there is a more optimal combination of the above steps
Success to all of you how are about to solve the same problem. I just have joined a postdoc at one Uni before even finishing my PhD at another one (still the thesis has to be finished, printed and defended). So I have to work at both Unis at the same time. As you may imagine I don’t have much time now to study how to install stuff and tune hardware, etc. My computers just must work in this period of my life. Therefore, GOD BLESS ALL OF YOU WHO CONTRIBUTE TO THE FORUMS. This let me solve the problem. Cheers
I have pasted items 2 and 3 of ThomasK's solution - I jumped straight in at step 3 and it worked perfectly
Here's the solution that worked for me.
First check your System group in Device Manager and see if you see an
entry called "Plug and Play Software Enumerator." If you don't see it,
then I have the solution for you.
I remembered accidentally deleting Plug and Play Software Enumerator
from the System group in device manager. I reinstalled it, and
everything worked fine.
Here's how to reinstall it:
You'll need to find two files (try doing a Google Search)
Then Add New Hardware, System Device, and have disk. Choose swenum.
Install it. Reboot.
Voila. It should be fixed.
And, here are the basic steps:
Go to System in Control Panel, Hardware tab, Device Manager button.
Click the + in front of 'System devices' (near the bottom), and look for a line that says: Plug and Play Software Device Enumerator
This fix will only help if you are missing that line, or if you have a yellow exclamation point on that line! If you have that line, and there's no yellow exclamation point, then stop here and look elsewhere - you've got a different situation.
Okay, now that you've confirmed that you're missing the Plug and Play Software Enumerator, or that it's broken:
Make sure you have the following two files in Windows (do a search - they should be there):
You don't need to do anything with them, just make sure they're there.
1) Copy machine.inf from WINDOWS\inf to a temporary location
2) Edit the temporary copy of machine.inf - remove the line that says "ExcludeFromSelect=*", and save the file
3) in Control Panel, choose "Add Hardware"
at the 'Welcome to the Add Hardware Wizard' window - click Next
at the 'Add Hardware Wizard' window (when it finishes searching) - click 'Yes, I have already connected the hardware', then click Next
scroll to the bottom of the list of 'Installed hardware', and click on 'Add a new hardware device', then click Next
click 'Install the hardware that I manually select from a list (Advanced), then click Next
click 'Have Disk...', and browse to and select the edited machine.inf file
scroll down in the list of 'Common hardware types', and click on 'System devices', then click Next
under 'Manufacturer' on the left, select '(Standard system devices)'
under 'Model' on the right, select 'Plug and Play Software Device Enumerator'
Once the installation is finished, and the Device Manager shows the Plug and Play Software Device Enumerator under 'System devices', the audio should now work (no reboot required)
Hello guys, could do with some help here, iv'e fromatted my computer fair few times but never have I come across a problem as weird as this.

i got same ploblem with u..but now my pc ok liao...put ur window cd at ur cd-room..go device manage..choice multimedia sound device..then delete..after delete go control panel found add new hardware..then in install..i no sure will working..but my pc is like this ok de...if cant then take go shop repair XP...
Click start, control panel,sytem and hardware.Click device manager then scroll down to sound/video&game controllers and click on the "+" tab.There will be a yellow exclamation mark next to the hardware with a problem,look at the sound card name.If you dont get anywhere just download sisandra (free) which tells you everything about your computer and its hardware etc and look what the sound card name is then go to driverguide.com,register for free and get your driver or go to the manufactures website.
Right, once a new Operating System has been installed, you have a few options:
1) Try and utilize the Motherboard CD, although if you have separate audio card, you will need the CD that came with it.
2) Browse CNet.com (download.com) or similar for the hardware specific drivers. Although long and tedious, it normally comes out with the right ones. - more for the experienced user
3) if you rolled back to XP from Vista, then only certain drivers are currently available. Most are for Service Pack 2 or older. Very few compatible drivers are available for XP rollbacks once Service Pack 3 has been installed.
If this is the case, you will need to install XP upto Service Pack 2, THEN install all your device drivers before commencing with Service Pack 3.
To do this correctly, without Windows Update getting involved, do not allow it to install SP3, instead, use the Custom Update option until you are happy all your drivers are in place.
