No alert sounds whenever I receive a new SMS. I searched all over this forum and I couldn't find anyone who had the same problem or a solution that worked. When I get a new SMS, all that sounds is the nominal "click" sound that is default for things like the keyboard or when you open the BiteSMS quick compose. This started after I installed several sound themes via Cydia. I think something told the iPhone to look elsewhere for tones and now it doesn't know where to look.

I've tried the following to correct this:
- restore from backup
- reset all settings
- delete all sound themes or sound controlling apps and reboot. I had downloaded Star Trek and Star Wars sounds yesterday. I also had an app called MyVolume.
- make sure BiteSMS isn't controlling ringtones. In fact, BiteSMS can't make the right tone, either when I let it control ringtones.
- install other sound theme to see if it will control things for me again. This worked for a little while and then failed again.
I REALLY DON'T want to restore as new because even when I restore from backup nothing gets put back where it's supposed to on a jailbroken phone. So, any help would be great.
