The Playback Noise Issue of TAS5805

When using the TAS5805, with a 100Hz sine wave and a 16kHz sampling rate, obvious high-frequency noise occurs.

The schematic diagram is as follows:

The captured speaker waveform is as follows:

I would like to know how to resolve this abnormal speaker waveform issue, and whether it is a software or hardware problem;

Which aspect should I start with to make improvements?
