Default [Q] - Internal speaker

Hi. I had a problem for a few days. The headset sensor, always reportet i plugged in the headsets, and unplugged. This generated a great cpu usage, as it alwas made like plugged - unplugged continuously.
I tried to use air pump to blos into the plugger, and i used an cotton buds to clean the headset plug. But did not work.

So when it again began with that trick, i tould him not to adwise me again.

But now if someone calls me, i cant hear anything except plugging the headset, or activating the speaker button.
It seems like if the internal speaker doesn't work anymore.

Someone any ideas? Or is it broken?
