This just started in the past month. Every day or so I find that the alert sounds, deleting a file & emptying the trash being the most obvious, just disappear. If I reboot or log out and log in the alert sounds return and after a day or so disappear again.
Any ideas what is causing this anomaly? I've deleted 'sound' plist but that didn't help. I'm using OS 10.6.8.
Mini 2.53, 4GB RAM, Mac OS X (10.6.8)
Is the interface sound effects checkbox checked in the sound system preferences? Check it again even if it looks checked just to reset that preference.
I'll give that a try and report back after a few days. Thanks
No luck with checking and unchecking user interface sounds.
Trash the sounder & Finder plist files
