I know that sounds like key clicks and the lock sound are more subtle than before. They're barely audible even with the volume turned up. The problem I'm having is that the New Mail sound has gone AWOL, no matter what I do. I've changed the sound, turned it off, rebooted, and from a suggestion on a different forum, a hard reboot. Multiple times. That did actually have the odd effect of making the keyboard and lock sounds louder, but the New Mail sound is still silent. BTW, in that other thread, the main complaint was that apps were playing different sounds from what were played, and selected, before. Methnks there's something rotten in the sound department.
