I found two solutions:
1) Line out audio from Euroscart - connect euroscart interface to tv and get audio out from 1 and 3 pin and ground from 4 pin -

- in this solution You will have audio not from all inputs (not from smart applications for example)
2) Go to Service menu, unlock advanced menu then go to CONTROL->CONFIG OPTION->HP LINE -> change from HEADPHONE -> LINE OUT - after changing this option we have line out from all sources, smart applications etc.
