TLV320AIC3104 MIC and Headphone cross talk issue

Hi Sir,

I used AIC3104EVM and used 4 rings earphone jack. When I playback and record in the same time. I can record the playback music. Do you have any solution to solve it? BTW, I test AIC3204EVM-U, it has the same problem. Thanks!

    Hello Jerry,

    The issue may be related to the common ground of the headset, if your application permits, it is recommendable to capture the record without playback. I'll make some research to find a way to improve this.
