Do not delete your drivers in Device Manager.

Go to Realtek.com and download and run the HD driver as often as it
takes to replace the MS one. MS driver has 06 date I believe.

Thanks to you both for your comments. I'll keep running the installer and
see what happens. Trouble is, as soon as you reboot, Windows goes right
ahead and installs the Microsoft drivers again without asking, which puts
me back to square one!

I never use Windows Update to get driver updates; unfortunately Service
Pack 2 comes with what Microsoft think are the best drivers and foil our
best efforts. I seem to remember the same thing happened with SP1 but it
was a lot easier to rectify (I only had to run the Realtek installer
twice).

When you install the RealTek HD Drivers you have to run the Installer
as many times as it takes to revert back to the Standard MS driver
and then one more time to get the new driver installed. So if someone
has been using Windows Updates or System Maker driver updates
they may have to run the RealTek driver 4 or 5 times before the new
driver is used. When I first ran one on my Laptop it went backward
5 times before the new driver showed up.

I have not seen any other driver with this behavior.

After installing SP2 I noticed that Windows had replaced my Realtek HD
Audio driver with its own older version. It also now appears twice in
the Device Manager; I can remove one of them with no ill effects but it
is redetected at next boot and reinstalled.

So I removed both of them, installed the latest Realtek driver and
rebooted. Now I still have two instances - one (called Realtek High
Definition Audio) with the Realtek driver and the other (simply called
High Definition Audio Device) with the Microsoft drivers. If I force
the Microsoft one to use the Realtek drivers it crashes horribly with a
BSoD (so I won't be doing that again!).

Once again I can remove the Microsoft one with no ill effects but it's
redetected and installed again on the next boot.

Something in my memory tells me I always had two entries under 'Sound,
Video and game controllers' but the second one wasn't called "High
Definition Audio Device" and the Driver Provider was Realtek, not
Microsoft. Trouble is, I can't remember what it was called, or what it
was for.

Anybody help? I could always do a System Restore to pre-SP2 and find
out that way but it's probably worth finding out here first whether I'm
worrying about nothing or not. It seems I've got two components of the
same chip with drivers from different releases.
