audio - Debian Wheezy no sound through jack output

I have strange problem with sound on my Debian wheezy powered notebook. Sound is not playing through jack output, but speakers are working just OK.

My ~/.acoundrc

A have checked if Headphone output is not muted in alsamixer too.

Is there a possibility to automatically switch to JACK when headphones is connected? It worked on Ubuntu 12.04.
