I used (notify.wav) for a test and it worked on a Boot or a return from Hibernation. Bob G
I dont know why, but ever since I've had XP, I've been unable to change the login sound. I saved a wav file in the same location as the default ones. I've applied the sound. But when I login, the default sound plays. I go back to the control panel it and says my sound should be set...
Anyone able to help?
Thanks,
