CC3200 Audio Booster Pack: Register configuration problem ( Using I2C bus )

Part Number:TLV320AIC3254

Hey Everyone,

I am using CC3200 Audio Booster pack with CC3200 launchpad. I am trying to configure the TLV320AIC3254 for 44.1kHz. Following are the clock and PLL configurations I am trying to make. 

            AudioCodecPageSelect(TI3254_PAGE_0);

            AudioCodecRegWrite(TI3254_CLK_MUX_REG, 0x03);       //PLL Clock is CODEC_CLKIN
            AudioCodecRegWrite(TI3254_CLK_PLL_P_R_REG, 0x91);   //PLL is powered up, P=1, R=1
            AudioCodecRegWrite(TI3254_CLK_PLL_J_REG, 0x38);     //J=56
            AudioCodecRegWrite(TI3254_CLK_PLL_D_MSB_REG, 0x00); //D = 0x0000 = 0
            AudioCodecRegWrite(TI3254_CLK_PLL_D_LSB_REG, 0x00); //D = 0x0000 = 0

The problem here is that these values are not actually being reflected in when I read back. Following are values read back immediately after writing: 

TI3254_CLK_MUX_REG = 0x01

TI3254_CLK_PLL_P_R_REG = 0x01

TI3254_CLK_PLL_J_REG = 0x00

I checked using oscilloscope that the read and write operation over I2C have no problem, it's going the way it should.

I also checked the application note of TLV320AIC3254 and the sequence is also being followed ( First software reset and then other things ). Also I checked the I2C section of CC3200 TRM, and I2C is being configured and used without any problems. 

I have already posted the issue in the SimpleLink forum (although, initially I thought that it's a different issue). Link: https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968/p/564160/2072550#2072550

There are other people having the same problem and they have posted in the SimpleLink forum, but without any reply or solution.

Any help would be much appreciated.
