Setup:
TLV320AIC23B codec
MCLK: 3.1457 MHz
Input frequency: 700 Hz
Base sampling rate F(s): 8.192kHz
Oversampling: 384 * F(s)
Do not want an anti-aliasing filter on the outputs because full bandwidth audio is needed (20 Hz to 20 kHz).
Problem:
~8kHz frequency heard on the microphone output and lineout outputs.
Question:
Where do you think this person is going wrong?
