Since upgrading my iPhone 4s to IOS 5.1.1 I no longer get text alerts. After messing about with the handset its also affecting –
- When the volume buttons are pressed on the home screen i get “ringer” and the speaker symbol appear but nothing more (ie. +/- volume)
- When playing back from iTunes with no headphones in, I get nothing through the internal speakers, nor do the volume buttons work, nor is the volume slider visable.
- When i playback Youtube content with no headphones in, I get nothing through the internal speakers, nor do the volume buttons work, nor is the volume slider visable.
- With headphones plugged in sound is audible and volume buttons work.
- Whilst using voicemail, (no headphones connected) i can play the message through the speakers and control volume using side buttons.
