No sound

[cgandini]

HI! Since a week or two my ipad stopped playing sounds in almost all apps i.e. angrybirds, tagesschau, qtom. Also when i type my screen password or hit the v-keyboard. I ve checked settings, switched off, etc etc? Curiously youtube does great, bbc radio also! Even trying to define ringtones and alarms.....
Anyway, any help will help
