I lost my sounds at startup and shutdown (all other sounds are played). It is not a hardware problem, because if I login as another user the startup sound is played. In 'Control Panel->Sound and audio device' the sound is set to the default windows sounds and the volume is at maximum.
I also looked in the registry, if the sounds are deactivated, but in 'HKEY_CURRENT_USER->Control Panel->Sound' the key 'Beep' is set to 'yes', the key 'ExtendedSounds' is also set to 'yes' and the (Standard) key has '(value not set)'. For the other user the keys look exactly the same.
I even exported the registry 'HKEY_CURRENT_USER->AppEvents->Schemes' from the other user and replaced it in my registry, but still no sound.
Is there another possibility to deactivate only the sounds at startup and shutdown? Thanks for your help!
