Besides the reboot and SIM trouble I have a lot of sound issues. Sometimes I cant change the volume, sometimes the music stutters or sounds scratched. A reboot and everything is ok for a few hours. I am the only user with this sound issues?

You are not the only one. See here Wired Sound issues. People are having similar challenges with the Nokia Lumia phones as well. That is the phone I have.

I am having it too. Sometimes through the headphones, or other connection, sometimes with text message, email, etc. notifications.

Thank you both for the feedback. So its a WP8 issue and have to be fixed by MS.

You'd better contact the service center asap.
