No sound at all Iphone 4S

Hi all,

Since a couple of days I don't get any sound from my Iphone 4S. Not any of the apps, ipod or phone function will produce any sound. I also tried earplugs and a dockingstation but it doesn't make any difference.

The Iphone has been updated to the latest IOS version and I used the restore and reset functions as well.

At this moment I'm running out of options, any suggestions from you guys?

Thanks,
