Part Number: TLV320AIC3104-Q1


we used TLV320AIC3104-Q1 codec, when calling, the codec PCM out(DOUT pin5) is delayed about 15 seconds,but mic's ADC has been inputed to MIC1R.
at the same time, RIGHT_LOP(pin 29) & RIGHT_LOM(pin 30) output is OK(no delay).
we use single mic, MIC1RP/LINE1RP(pin 12) & MIC1RM/LINE1RM(pin 13), MIC2L/LINE2L/MICDET is not used.

How can I try to find out the solution to the problem?
