ADSP-BF706 EZ-KIT-MINI

Hi Analog Team,

We are using ADSP-BF706 EZ-KIT Mini EVB for Audio Testing. In that EVB J1 jack is for Input (MIC) and J2 Jack is for Output (Speaker). Input is working with Line-IN but when we try to connect with MIC of Headphone Input is not working.

We tried to give MICBIAS by wiring from P7-5th pin to J1-2nd and 3rd Pins with 2K series resistors. We have enabled MICBIAS in R10: Record Microphone Bias Control, 16,400 (0x4010). but MIC of Headphone is not working.

Is there anything to do. Please suggest us.

Thanks & Regards,

Rekha.
