All of the sudden sounds are gone but speaker is fine when I play music or listen to the radio. I mean clickimng sound when I turn it off, clicking sound when typing on the keyboard,sounds associated with apps, etc, etc. Also the sounds when receiving and sending e-mails. I checked of course General, Sounds and everything is turned on. Also, when testing sounds for e-mail - there are tons of it - everything is OK. Anybody have an idea what could possibly by wrong?
