ADAU1701 bad run quartz

Hello,

 

Faced with the problem, the quartz resonator is run badly.

The load of 22 pF connected in series via a resistor 100 ohms (OSCO).

Wiring diagram standard.
Runs only the touch of a finger on the quartz body.
I Tried 18pF - the best start, but still a problem.
Tried one shoulder connect 18pF and 36pF for the second - it became better, but still a problem arises.
Perhaps a bad quartz quality factor, but it is possible to somehow improve the reliability of start?
