    Hello,

    did you check the projects in

    \Projects\STM32F4-Discovery\Applications\Audio\Audio_playback_and_record

    and 

    \Projects\STM32F4-Discovery\Examples\DAC\DAC_SignalsGeneration

    in the STM32Cube_FW_F4 directory?

    regards,

    Yep. I did it. but I want from SD card to DAC only. not use I2S or CS43L22.

    Then at this point, you may need to dirty your hand a bit and merge the 2 examples.

    Sending the data to the DAC instead of the I2S is not that difficult...
