Question
How to avoid audio distortion in BF706mini BSP audio example?
Answer
The below modification to be applied in "adi_adau1761.c" file located in ADSP-BF706_EZ-KIT_Mini-Rel1.1.0 board support package
<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 replace the attached file in the below path restart CCES. This would resolve the audio distortion issue.
