TPA6304-Q1: 【TPA6304】The voltage of TPA6304 is about 18v, which leads to output oscillation.

This problem occurred when TPA6304 was de-mute at a voltage of about 18v . Changing the inductance and capacitance of the power supply input will affect the probability of oscillation, and TPA6304Q1EVM will also have the same problem when changing C4 capacitance or L9 inductance.

When the output oscillates abnormally, it is easy to damage the device when the protection function of the output fails. I want to know the reason of this problem.
