No sound on normal use

[Ktysai]

On my Nokia 830 for a day or so the sound does not work. The phone does not ring when I receive a call, alarm or when I put a song.

I've tried a couple of soft resets without any luck. The wired headphones are working, fortunately. Only one funny solution has worked for a few seconds: blowing on the loudspeaker. I'm not sure if it's a software or hardware issue.

Somebody have some other suggestion before trying a hard reset and finally tear up the phone?

Thanks!

Hard reset has work, let's hope it's a permanent solution.
