I'm sure some people will think I'm being nitpicky, but I've noticed that my Enchanted Blade spell doesn't go "Ka-Ching!" anymore when I cast it. Neither do Magic Screen, Missile Shield or Armorplate. I'm casting them out of battle mode, and I distinctly remember that they used to make some pleasing audible feedback to let me know that they had been cast. Perhaps it was changed in one of the patches? I kind of miss it...

It's strange.... tray patch...

I had the same problem after I accidently changed my sound driver using the Wiz8 setup program.

Check to make sure that the correct sound card is selected in the 3d setup program
