TLV320AIC3104: background noise

Part Number: TLV320AIC3104

Hi 

When our customers use the TLV320AIC3104 audio codec to make voice calls, if they speak outdoors in an environment with background noise, the other party will not be able to hear the voice of the calling end, and the voice will be broken and distorted. Based on your experience, this part may be related to the parameter tuning of the Audio codec part? Audio input is from Pin12/Pin13.
