ADZS-BF706 EZ-KIT test program experiencing bad distortion

I think I am experiencing the same problem with the audio test program as shown in this previous post but I am unable to fix it. Can you direct me on the file that needs to be updated?

The solution says something about a file but I can´t find such file nor any line related to the solution:

We have a patch for you to apply to adi_adau1761.c. This source is part of the BF706 BSP and will be included with the example projects in system > BF706_EZ-Kit_MINI > drivers > codec > adau1761. For the two calls of adi_sport_ConfigClock() replace the forth parameter (true,) in each with:

  • Hi,

    You can find "adi_adau1761.c" file (in which you need to apply below modification)from below mentioned BSP installtion path after successfully installing ADSP-BF706_EZ-KIT_Mini-Rel1.1.0 board support package on your PC
    <Installation>\Analog Devices\ADSP-BF706_EZ-KIT_Mini-Rel1.1.0\BF706_EZ-Kit_MINI\Blackfin\src\drivers\codec\adau1761

    For the two calls of adi_sport_ConfigClock(), replace the forth parameter (true,) in each with:

    #if __CCESVERSION__ >= 0x02040000
    false, /* CCES-11151 fixed */
    #else
    true, /* passing true compensates for CCES-11151 */
    #endif

    or you can replace the attached file in the below path restart CCES and let us know how you are getting on

    <Installation>\Analog Devices\ADSP-BF706_EZ-KIT_Mini-Rel1.1.0\BF706_EZ-Kit_MINI\Blackfin\src\drivers\codec\adau1761
