Ok, I have a strange problem. I've been Googling around, and a few people had this same problem, but there have been no fixes. Whenever I used hit my Windows Key+L shortcut (short for Switch User) a sound would play, Windows XP Logoff Sound.wav, and when I would log back into the account, it would play Windows XP Logon Sound.wav. However, as of today, they don't play. There is a catch, however. If after I turn on my computer and log into my account, I log out of the account completely, and log back in, the aforementioned sounds begin to work via the shortcut again. I have checked Sounds and Audio Devices in control panel and verified that the sounds are enabled, and I downloaded TweakUI to verify that "Beep on errors" is checked, and I just don't know what else the problem could be. Any help would be greatly appreciated, thanks!
