Have you checked that the output isn't muted, has the audio routed to the output you're using and has a suitable volume?
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.
Audio data should be sent over I2S, so there's no I2C traffic during audio playback.
