hi all:

  i am now woking audio function. i am sure i can transmit aduio data  from external device -> aud6 -> aud7->ssi2, but i don't konw how to let SSI port audio data as esai "SRC", I also not found any doc to describe this function from freescale offical document. A freescale told me it maybe ues ASRC, but i am not understand, can anybody give me some suggestion?  i think it maybe need modify kernel and Android HAL(tinyalsa_hal.c)

  our board is base SDB, Android 4.4.2
