So this has happened to me before, and now once again. I've lost some system UI sounds and keyboard tap sounds... Before, I reflashed after formatting SD card, issue fixed. However Saturday i noticed the sounds had stopped once again, formatted sd, reflashed CM9 Beta 2, no system UI sounds. Not having them isn't really a deal breaker, but i'm curious as to why they've stopped working. the only change i've made to my phone was to ditch Friendcaster and retry Facebook...I've done some restoring using titanium backup, could it be somewhere along the way some system settings have been corrupted? (NOTE, all the system UI sounds are in \system\media\ui like they're supposed to be, when i go to type w. keyboard sounds enabled, and headphones plugged i hear the system try to make noise, but no taps. Kinda stumped, any ideas?
EDIT: I've tried multiple keyboards, no sounds....
