CCS/TLV320AIC3106: Audio playback issue with CC3200 I2S

Tool/software: Code Composer Studio

Hi,

I am working on TLV320AIC3106 interfaced with CC3200's I2S port. I could read I2S data send out from the audio codec and I've sent it to cloud and is working fine. There is also a speaker in my application. For testing the speaker I bypassed Line2LP/M to MONOLOP and it did work fine. Now I need to play audio which is sending from the processor to TLV320aic3106. but this is not working unfortunately. Data is sending to the audio codec, which I verified using oscilloscope. Please see the register configuration below and check whether I missed anything? 

    AudioCodecPageSelect((unsigned char )0x00);
    AudioCodecRegWrite((unsigned char) CODEC_SW_RESET, codecPage0Regs.SW_RESET);
    // clock generation and control
    AudioCodecRegWrite((unsigned char) CODEC_CLOCK_GENERATION_CONTROL, (unsigned char) 0x02); // CODEC_CLKIN uses MCLK(CLKDIV_OUT)
    AudioCodecRegWrite((unsigned char) CODEC_ADDITIONAL_GPIO_CONTROL_B, (unsigned char)0x01);
    //   AudioCodecRegWrite((unsigned char) CODEC_PLL_A, 0x91);// CODEC_PLL_A_RESETVAL);
 //   AudioCodecRegWrite((unsigned char) CODEC_PLL_B, 0x60); // J value 24
 //   AudioCodecRegWrite((unsigned char) CODEC_PLL_C, 0x09);
 //   AudioCodecRegWrite((unsigned char) CODEC_PLL_D, 0x00);

    AudioCodecRegWrite((unsigned char) CODEC_GPIO1_CONTROL, 0x28);// 0x28);   // clock out on gpio1 pin

    AudioCodecRegWrite((unsigned char) CODEC_SAMPLE_RATE,0x00);//0xAA);  // fs = fsref/n

    AudioCodecRegWrite((unsigned char) CODEC_MIC_BIAS_CONTROL, 0xC0);// (unsigned char)0xC0);  // MIC bias

    //When selecting an input, unmute the PGAs after routing the input and powering up the ADC.
    AudioCodecRegWrite((unsigned char) CODEC_LINE2L_LEFT_ADC_CONTROL, 0x80);
    AudioCodecRegWrite((unsigned char) CODEC_LINE1L_LEFT_ADC_CONTROL, 0x7C);  // power up left ADC
    AudioCodecRegWrite((unsigned char) CODEC_LEFT_ADC_PGA_GAIN_CONTROL, 0x00); // unmute PGA

    if((temp_readptr&0x01)==0x01){
        monolop_success=1;
    }
    else
        goto SET_MONO;
