Hi, 

     I used the TPS65920 to generate 11.2896MHz , and connected this clock to CLKS in AM3703. then , I use an Audio DA  connected to McBSP2 , and I configured the I2S to master. 

     the Audio can be out , but ,just even i setted to dual mode , there is only single audio out  , not stearo . and there are some noise. 

     How to config this?any one know?

    Hi,

    Did you made all the settings for Audio I2S format with dual phase frame mode?

    The description is in the TRM 21.4.2.4 Frame Phases (Dual-Phase Frame I2S Support).

    A sample setup is listed in Table 21-18. Assumptions for the Dual-Phase Frame Example (p3106)

    Please note that word lenght for both phases must be set with corresponding values.

    Hope this helps.

    BR,
