    Hi,

    I looked over your mixer configuration and saw some problems.

    Switches "Right Playback Mixer Right DAC" and "Left Playback Mixer Left DAC" are set on "false".

    Please open alsamixer navigate to before mentioned items and activate them (press M key).

    Also if in your DSP program you don't have I2S inputs configured you should set the DAC Playback Mux to AIFIN and not DSP.

    Regards,

    Bogdan
