OMAP L137/C6747 Audio example PSP and I2S mode

I would like to convert the audio example for the C6747 in the PSP 1.30.01 to use i2s rather than DSP mode.  I made the following changes

Aic31.c

const Aic31_Params Aic31_PARAMS = {
    ICodec_CodecType_AIC31,         /* acType                 */
    ICodec_ControlBusType_I2C,      /* acControlBusType       */
    "NONE",                         /* acCtrlBusName          */
    ICodec_OpMode_MASTER,           /* acOpMode               */
    ICodec_DataType_I2S,            /* acSerialDataType       */ <---- change 1
    (Uint32)ICodec_SlotWidth_16,    /* acSlotWidth            */
    ICodec_DataPath_TXRX,           /* acDataPath             */
    0,                              /* isRxTxClockIndependent */
};

audioSample_io.c

Mcasp_HwSetupData mcaspRcvSetup = {
        /* .rmask    = */ 0xFFFFFFFF, /* All the data bits are to be used     */
        /* .rfmt     = */ 0x000180F0, /*  <------ change 2
                                       * 0 bit delay from framsync
                                       * MSB first
                                       * No extra bit padding
                                       * Padding bit (ignore)
                                       * slot Size is 32
                                       * Reads from DMA port
                                       * NO rotation
                                       */
        /* .afsrctl  = */ 0x00000000, /* burst mode,
                                       * Frame sync is one bit
                                       * Rising edge is start of frame
                                       * externally generated frame sync
                                       */
        /* .rtdm     = */ 0x00000003, /* slot 1 is active (DSP)               */ <------------ change 3
        /* .rintctl  = */ 0x00000003, /* sync error and overrun error         */
        /* .rstat    = */ 0x000001FF, /* reset any existing status bits       */
        /* .revtctl  = */ 0x00000000, /* DMA request is enabled or disabled   */
        {
             /* .aclkrctl  = */ 0x00000000,
             /* .ahclkrctl = */ 0x00000000,
             /* .rclkchk   = */ 0x00000000
        }
} ;

I also put the in the same changes in mcaspXmtSetup structure.  However I got no audio pass-thru.  Any help from the PSP team would be appreciated.

Thanks,

Fawad
