Ok thanks for you answer, but I can't see a register for volume control, the audio core register map contains only control, fifospace, leftdata and rigthdata registers, where I can find the register for volume control ?

You can refer audio codec data sheet for volume control register for line out and head phone output.  

 

You have to send these register value using I2C interface.
