We are debugging Audio IC TLV320AIC3110 sent by FPGA signal to TI. The sound output will be truncated if the signal is higher than about 2.3v, resulting in noise in the sound output. If the volume input is small, there will be no problem. If the volume is turned up high, it will be cut off. Please refer to the following waveform: I don't know whether it is the problem of register configuration or the problem of hardware circuit.
