No Sound

[MSG68]

I'm asking in several places for help as this problem is driving me nuts. I
do not think it is the card that's bad as I think it came on after an update,
however the problem is that the system tells me that the driver for the
realtek hardware device has been loaded sucessfully by Windows , but that
hardware device cannot be found (code 41). I have a Toshiba A105-S4334 and I
have unistalled, installed, changed just about everything around and still no
sound. It started with no keyboard, dvd/cd or sound and now it's just no
sound. Can someone please help me fix this or I am just barking up the wrong
tree?

Next time please crosspost instead of multiposting. I answered your post in
XP General already. It would have been more useful if you had included the
information about thinking the problem arose after an update, but my answer
would have been the same.

Please find your post in microsoft.public.windowsxp.general and read my
reply. If you have questions, please keep it in that thread as I won't be
monitoring this one.

"It started with no keyboard, dvd/cd or sound"

Why was that ? No drivers installed ? Or were
you editing the registry ? Bad things happen
if you delete all the UpperFilter/LowerFilter
instances.

No I'm not sure I simply came in to do some work on the computer and none of the things I mentioned worked. A friend from the military computers folks said try reinstalling keyboard, ect drivers so I did and got back 2 out of three.

One option would be to use a System Restore point, to a date just
before the failure. That would presumably restore the registry and
drivers to a state just before the failure. (Also wiping out the
fixes you've just done.)

Otherwise, for an amateur like me, it would be hard
to determine just what part of the protocol stack is
failing. You can try reinstalling the driver, and
in the case of HDaudio, there are the two parts,
Microsoft UAA component and Realtek driver part.
For AC'97 sound, just the RealTek driver is responsible.
The AC'97 or HDaudio should be enabled in the BIOS, in
order for an installer to work. Typically, the ReakTek
driver comes with KB888111 included in a separate folder.
Some downloads, like say one from HP or Dell, might include
KB888111.xpsp2.exe, implying there are separate versions
of the KB888111 UAA package included, dependent on OS
service pack level. The installer included in the package
should run the right one for you.

There is a recipe for uninstalling and reinstalling,
which seems to have something to do with banishing the
current version of UAA, so that the UAA in the installer
can take its place. This is paraphrased from an Asus
Tech Support email.

*******
1)Go in safe mode

2)Disable the HD audio device under Sound Video Games
controllers, do not uninstall it here!

3)Disable under the system devices "Microsoft UAA bus driver for high
definition audio", do not uninstall it here!

4)Now uninstall the "Microsoft UAA bus driver for high definition audio"
(via this device manager in safe mode), the HD audio device will then
also be uninstalled automatically

5)Install the latest driver for your motherboard.
*******

For AC'97 type audio, it should be a more straight
forward driver install.

A part I don't understand, is for the HDaudio packages
that include several versions of KB888111, none of them
so far included a version for xpsp3.
