Yes I have checked all that things. I have 2 routes from VOUTHP{LR} and 
from VOUT{LR} and I think it's ok because of info in logs "asoc: 
uda1380-hifi <-> pxa2xx-i2s mapping ok".
I have also observed that if I change Output Mux from DAC to Analog 
Mixer and change Anolog Mixer volume up the noise and louder.
In my opinion problem is somewhere else. I think that I forgot to enable 
sth in ALSA. As I said when I enabled I2C debugging data flows only when 
playback is starting or when I change values in alsamixer, when music is 
played no data are send to codec.
