I began to enable my iPod's sound today so that Calender alerts would work and a distressing problem has arisen. The AIM application makes a sound, which cannot be turned off. I see the switch in settings and I turn it off but the sound plays every time I am im'ed. I know I could use Meebo, or a similar service, but the native client drains battery life less. Does anyone else have this problem? I tried wiping the iPod completely...twice...and reinstalling the app, but it won't work. The sound is supposed to be off, but isn't.
