Complete Conexant HD audio driver set for Windows XP
For many HP and Compaq laptop & desktop models.
(It's very important to install this first, then the audio driver below)

Conexant audio driver
The above files are for a Compaq Presario C501TU Notebook PC which has the same motherboard as the E-System 3090 UK notebook.
These files will most likely work on many other HP/Compaq machines needing downgrading from Vista to XP.
Give it a try and let us know the result. Hopefully, you will have sound once these drivers are installed in the proper order.
Fix #2 (a bit more complicated to use but works)
After wasting several hours of work time uninstalling and reinstalling and trying to figure this crap out, I finally
searched the internet and came up with the following fix for getting Realtek HD audio to work in Windows XP w/SP3.
For everyone else who comes across this thread, here is the solution to this yes, Microsoft, problem (below).
SP3 not only doesn't have the specific update needed in order to install Realtek High Def Audio, but it also has problems
installing it. There is a rememdy for this someone built below. Realtek's drivers include an install of this needed update
with their driver package, but it only applies to Windows 2K and XP SP1/SP2--so that's why you have to do the work-around.
ED#73 : Microsoft Windows XP SP3 RC Does NOT Support High Definition Audio
In Windows XP, if we need to run a High Definition Audio (HDA) device, we would have to install the Universal Audio Architecture
(UAA) High Definition Audio class driver. This is either the KB835221 (for SP1) or the newer KB888111 [link posted at the bottom of this thread] (for SP2 or SP1).
However, this does NOT work for the latest Windows XP Service Pack 3 Release Candidate Release. If you've already tried installing
the Windows XP Service Pack 3 Release Candidate v3264 with a High Definition Audio (HDA) device in your computer, I'll bet you have
encountered problems with the audio drivers as I did.
When you try installing the KB888111 which works for SP1 and SP2, it will not work for Service Pack 3, at least for the current SP3
RC v3264. Instead, you will be prompted with a message saying that the current service pack installed is newer than the fix you are
trying to apply. Even the older KB835221 does not work.
It looks like Microsoft "forgot" to add the Universal Audio Architecture (UAA) driver for High Definition Audio devices in the
latest release candidate of the Windows XP Service Pack 3. We hope they will not forget to add it into the final release.
Fortunately, all is not lost. There is a way to fix this problem for the current release candidate.
You can try tinkering with the Universal Audio Architecture driver's INF file to make your Windows XP SP3 think that the driver
is meant to be installed on Service Pack 3. redxii from MSFN forum did just that and created a modified KB888111 driver which is
available for download. Before I tried it out, I found that the feedbacks were all positive!
I tried it on my Windows XP SP3 system and it worked! Just download the rar file file below, extract it and then
right-click at the ? mark at the Device Manager where your High Definition Audio (HDA) device is located and reinstall the driver
by pointing to the folder you extracted the files to. After that's done, install the audio driver for your motherboard. That's it!
If you need the KB8888111_hotfix (or add-on, as it's called), you can download it from the link below.
There are four main packages, all available in 24 different languages.
KB888111w2ksp4.exe - supports Windows 2000 SP4
KB888111xpsp1.exe - supports Windows XP SP1
KB888111xpsp2.exe - supports Windows Xp SP2
KB888111srvrtm.exe - supports Windows Server 2003 Standard (32-bit version only)
Have fun with Service Pack 3!
