No Sound - Kernel Wave ! Will not stop happening.

[Guest GW]

This keeps happening to this computer. Sound stops. Device manager shows

yellow ! and the device error states: Windows cannot load the device driver

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

 

I cannot stop this problem. Please help...

 

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.
