NO Sound Resolution - Kernel System Audio

[Guest]

I have lost all sound twice now in the last two months. I did the fix below
both times and it worked. Does anyone know why I have to keep doing this?

Thanks

On the System Properties panel, Advanced tab, Environment Variables button,
under the User variables click New and create a variable named
devmgr_show_nonpresent_devices with the value of 1.
Open the Device Manager and select Show hidden devices from the View menu.
Under the Sound, video and game controllers group, find your sound card(s)
and
disable it/them (don’t need to uninstall).
Then uninstall the following devices:
Microsoft Kernel Audio Splitter
Microsoft Kernel System Audio Device
Microsoft Kernel Wave Audio Mixer
Microsoft WINMM WDM Audio Compatibility Driver
Select Scan for hardware changes from the Action menu. Now the system should
redetect and reinstall the deleted devices automatically. You may get non
signed driver warnings, click continue.
Enable the devices you disabled in step 4. You may need to restart the
computer.
The problem should be disappeared, you should be able to play sounds.

for this hardware. The driver may be corrupted or missing. (Code 39).

I had a VERY similiar problem a few months ago. But it was with my NIC.
Every three weeks or so I'd have to delete it and then let win redetect
it again. I got a new NIC and problem solved.

You have used the correct drivers from your manufacturer, and NOT winupdate?

If you have recently updated the driver, and the problem appeared after this
update, roll back the driver

No, have not touched the driver. It's the same one from 2001. If you go out
and search for an update, there is not one.
