Main part of dongle is PCM2912 circuit from Texas Instruments. On one side of the board is USB type A connector and on the opposite side are two 3.5' connectors for headphones and microphone. Green LED signalize playing and red recording. Button is for mute of microphone. I am using PCM2912A for audio codec & INA21AIDWT for pre-amplifier. I am finding continuous noise at the audio output, Can you please guide me the arrival of noise and give me an solution to solve it. Its a serious issue going on.Kindly give me an solution to solve it as soon as possible.
