We have a mixer design that use tlv320adc3101-q1 chip. The microphones are connected to a pream chip and then the pream is connected to the ADC. One for a while, we could not hear any microphone input. We measured and found out that the signals are ok right after the pream (pream->ADC). Somehow, there are no output from the ADC. Please help! Thank you very much.
