Hi,
I'd installed a PC based on ASUS P5B-VM motherboard (E4300 CPU, 2GB
RAM). To keep the cost of build low, I determined not installing extra
display & sound card and use existing low speakers (just ordinary 2
loud speakers) . Installation of Windows XP ran smooth until I found
that there was no sound coming out from the powered on loud speakers
even Windows XP booted up successfully. Also, from XP control panel ->
Sound & Audio device, XP seemed doesn't detect sound & audio device at
all.
What's worse, when I tried install SoundMAX drivers from service
support CD came with ASUS motherboard. Installation couldn't complete
with error message "The HDA Audio bus driver is required and not
found".
I would like to ask is ASUS tailored made audio driver was needed to
onboard sound to work ? If so, what's the meaning of that error
message (PS: all hardware & driver disk were original from ASUS
dealer). Do I need to install additional XP service pack to eliminate
the above error message & make SoundMAX installation proceeded ?
Tks!
HDaudio consists of two parts. WinXP needs an additional component
called UAA. The first release was KB888111. That version used to be
included with HDaudio driver packages. Which means, if you don't want
to get that one from Microsoft, you can find it by looking for the
right motherboard driver packages instead.

It is possible there is no UAA bundled with the Asus CDROM. In which
case you should get it from the Microsoft web site. Or find an old
one bundled with an early HDaudio package.
UAA is probably the "HDA Audio bus driver" referenced in the error
message.
If you don't wish to deal with Microsoft, this is my previous
recipe. This actually appears to be KB835221, which is also mentioned
in the above link:
********
Unzip the three parts, then execute the first part. Unrar will
prepare the CMI folder. The "BusDriver" folder contains 32MB
of Microsoft's stuff, for 26 different locales. Select a kb835221.exe
from the right language folder for your OS. Too bad this
part cannot be a 1MB single language download from Microsoft
themselves.

If you are at all concerned about this process, set a "restore point"
before adding kb835221 and then installing the driver on the Asus
CD. You can always back out later, if you have a restore point.

Every audio setting mentioned default in manual
http://dlsvr01.asus.com/pub/ASUS/mb/socket775/P5B-VM/e2642p5b-vm.pdf
section 2.4.5 Onboard Devices Configuration was not changed.
Also, it seems the SoundMAX utility in support CD is just an enhanced
feature for 8-channel audio capability (manual section 3.3.1 SoundMAX®
High Definition Audio utility), not a pre-requisite for sound to be
fed from on board sound circuit to loud speaker (PS: I had connected
the loud speaker input to Line Out port as indicated in manual section
1.10.1, page 1-28).
