I am using Windows 7 pro 64 and am having a problem where none of the system sounds will play. All other audio seems to be working as per usual; it is only the system sounds that aren't working.
I went to the
Sounds settings window and when I hit the "Test" button for various sounds, nothing plays. So, I ran
sfc /scannow but all my files were fine, so I created a new user and logged into the new account, and all the sounds were playing fine. Also, if I go to the .wav file on my main account (problem account) it plays fine in windows media player.
I'm not sure what else to do, I must have some setting that I can't find disabling the system sounds or something.
