When I look at the signals. 

Everything looks fine except the data from the codec (SD EXT), I'm sending in a line signal audio to the analog in, and now I want the analog signal to be converted and send back to the STM32, that would be nice, but nothing happens the pin just stays low :-( 
So does any one haveexperience with thees type of code, so they can help me in the rightdirection, you help is highly appreciated Thank.

PS:when sending data to the codec, the analog out is “moving”.
