I recently replaced a failed motherboard with an Asrock 4CoreDual-SATA2 board. Only one unexpected surprise - no audio.
Figured no big deal I'll just use the supplied drivers disc. XP however says it can't find the drivers. Figuring I may have an imperfect disc I went to the Asrock website and downloaded the available drivers. Still no sound.
Audio is a Realtek ALC662 Anyone know how to get XP to recognize Windows drivers?
System is dual boot with PCLinuxOS 2009.2 where the onboard audio plays just fine.
I have that board. 4CoreDual-SATA2 R2.0.
Right now, I have both the onboard RealTek HDAudio installed, as well
as a separate sound card (CMI8738 PCI based). I can switch between then,
using the controls in the Sound control panel. Right now the CMI8738
is my sound card, but occasionally I switch over to the RealTek for
some comparison testing.
If I go to Start:Run, run "msinfo32.exe", select Components, then Sound, I get...

The PCI sound card uses an IRQ. I don't see one for HDAudio.
Check the BIOS, to make sure the HDAudio is turned on. (I only
turned mine on recently.) WinXP can handle having multiple
sound devices turned on, but likes to select one of them
as the Primary device. That is what the Sound control panel
is for.

I got a RealTek driver here. Two weeks ago, release R232 was being offered.
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=14&PFid=24&Level=4&Conn=3&DownTypeID=3&GetDown=false
The download is 30,914,690 bytes for the one I got. Their servers
are slow, so you may want to walk away from the computer, while it
downloads. The Asrock download could just be a copy of one of those.
Inside, you'll find it consists of two parts. The MSHDQFE folder
contains "kb888111xpsp1.exe". The purpose of me identifying that
part of the installer, is to point out that Microsoft issued an
important part of your HDAudio solution, in KnowledgeBase article
888111.
http://support.microsoft.com/kb/888111
If you were to actually download something from the 888111 web page,
it would contain support for 25 languages and three different service
pack levels. You would end up using a little over 1% of your download,
to good effect. So that is pretty wasteful.
The RealTek installer, includes a copy of UAA for you. It is the
English version only. The other 24 languages are missing.
kb888111w2ksp4.exe
kb888111xpsp1.exe
kb888111xpsp2.exe
Notice something ? There is no version for WinXP SP3. The SP3 service
pack already has 888111 bundled with it. If you have SP1 or SP2,
then the RealTek installer should use the appropriate file.
If you look in Device Manager, under "System Devices", and 888111 was
installed, you'd see
Microsoft UAA Bus Driver for High Definition Audio
(Driver = hdaudbus.sys)
The other part of the solution, is the RealTek specific part. The installer
has a WDM folder. There are INF files in there, and one entry in one
INF file, should match the characteristics of the 662. (It could be,
the match was against HDARt.inf.)
Now, if that part was to install, you'd see a device in the
Sound, Video and Game Controllers section. There would be a
"Realtek High Definition Audio". The driver list is extensive,
and consists of both Windows elements and Realtek files.
The "RtkHDAud.sys" is an example of just one of the files.
Anyway, that is an overview.
Enable the BIOS setting for HDAudio.
Unzip the RealTek downloaded ZIP file. (Even Windows has a built-in
unzip function in its folder view capabilities.)
Drill down until you see "setup.exe".
Double click setup.exe to install the driver.
If you have problems, please report what you see
in Device Manager.
Mine went in, no problemo. I had WinXP SP3 already,
and installed the RealTek R232 driver on that. People
do have problems with RealTek, and if it doesn't work
out, report any error messages or yellow marks you
see in Device Manager.
The file "setupapi.log" on your C: drive, contains
info on attempts to install drivers.
HTH,
Paul
