iPhone 4: Text Tone, Lock Sounds Stop Working
For the last month, my iPhone 4 (iOS 4.3.2) just stops playing the Text Tone when I receive a text message and the lock screen Sounds also stop working. Pretty much the only tone that is working correctly consistently is the ringtone for incoming voice calls.
When I go to Settings- Sounds- Ringtone - and choose the various options I get the sample sounds to choose the appropriate ringtone
When I go to Settings - Sounds - Text Tone - and try to sample the tones the phone simply vibrates. I cannot hear the tones at all
I have Settings - Sounds - Silent - Vibrate = ON
Sounds - Ringer and Alerts - Vibrate = OFF
Changing them around makes no difference at all.
When I reboot the phone, sometimes the text tone will work for a minute until the phone goes to sleep. Then the sounds stop again.
I have lock sounds turned on as well. Usually works for the first unlock, but if I unlock after a period of inactivity the sound goes away.
I've updated the OS, I've restored the phone. Nothing is working.
