Hello,
We are working on C5515 EZDSP TI's board. We are facing problem with the board. We have made hearing aid application on c5515 ezdsp. We have inserted headphone in Stereo out female jack and mobile is connected to stereo in. When we get a call or dialed a call our input signal(Input signal to AIC3204) is effecting. we have tried by shielding the device with aluminium and copper foil, but, we haven't get any better result from that.
Can anyone please suggest me, how to remove this noise?
