This happens because there is insufficientpower supplied to the amplifier.
If the requirements go beyond this, the amplifier “clips” the input signal.
This can be because the volume is too high or the amplifier gain is improperly set.

How Does Clipping Happen?
Effects of Clipping
Audio clipping can be hard, soft, or limiting.
Hard clipping delivers the most loudness but also the most distortion and loss of bass.
Soft (also called analog) clipping delivers a smoother sound with some distortion.
Not all clipping is bad or unintentional.
It’s advisable to record digital audio while keeping the input signal within limits.
