Thread Summary

                The user requested a schematic review for the ADAU1761BCPZ audio codec. The final answer confirmed that input pins LINP and RINP should be tied to the CM voltage, not grounded, and that the 1K ohm resistors on LOUTN and ROUTN should not be populated. The user also clarified that the input signal is connected to two different inputs with 0-ohm resistors for flexibility, and that the pin numbers were corrected. A subsequent issue with no output on the line outputs when using a 4KHz square wave input was noted, with the only difference being the MCLK source (oscillator vs. FPGA).
