Strange Sound Problem

[h90]

just tried to call someone with skype, had no sound.

Looked at the small speaker icon on top right.

There is non anymore.

No speaker icon, no sound.

I didn't install anything, I didn't change anything.

I reboot the computer but still sound is gone.

Anyone has an idea, why this could be and how I can get it back?

ubuntu-bug audio

this than tells that it is muted amd you can start a mixer somehow.

than unmute everything.

But problem: After every restart it is muted and need to be unmute over the Terminal

Microphone does not work at all anymore.

I think it is somehow time to have a look at Win7. Ubuntu really makes too many troubles.
