dear sir,
our current product uses this audio codec (TLV320AIC3106). when we communicate using our product to a mobile phone, echo heard. Its happens specifically when mobile phone guy is talking for more then 1 minute. after 1 minute of talking, mobile phone guy can hear his own voice/echo. but from our product side, its good. we can talk and we dont hear the echo. take note that our product is using tlv320AIC3106 and no echo in our product.
the mobile phone is working fine and ehco only happens when communicating to our product.
may i know why its happening? any settings in codec (tlv320AIC3106) related to this issue?
