Running XP Home (SP3)
Problem :
Lost Sound Icon in System Tray
Played Some sounds and Not Others
Some sound in WMP, no sound on UTube or other apps.
No Start Up/Log Off Default Sound
No Alert Sounds
For the last 2 days I have searched the web trying to find a solution to this problem. I have updated drivers, ripped the soundvol.exe file out of the XP Disc, tried numerous other tweaks and finally I have found a solution that actually worked.
When I opened the Drivers32 Regestry Key in regedit, I noticed there was only 1 value and I could not alter or open it. This Registry entry should have a good number of driver value entries in it such as midimapper, wavemapper etc but they were not there. Therefore I realised I needed to alter the permissions to this key and try to reconfigure what I thought were my lost drivers.
However I realised they were not lost but instead a malicious script had altered the permissions making the registry entry look empty. I simply removed the permissions the malware added and the drivers all re-appeared as soon as I closed the permissions box.
Solution:
Open the Registry : Start, Run, enter "regedit", click ok.
In Registry - Navigate to Drivers32 key.
HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Drivers32
Right click on the Drivers32 Registry Folder, then click on "Permissions".
Remove all the permissions for Drivers32 for ALL users and then press "Apply". You will see that all the drivers, codecs etc for Drivers32 will re-appear.
Reboot and your system will have all its sounds back. I was so relieved when I turned the system off to hear the defeault log off sound nice and loud. As the system started again I was more relieved to hear the start up sound also. Now all my sound programs are working again and all the sounds that were lost are now back.
I am sure this will help all those out there who were as frustrated with this as I was.
