Sound processing method, and sound processing system

A sound processing method of a sound processing system that is provided with sound device, a first sound processor, and a second sound processor,

• wherein:
• the sound device receives a first sound signal from the first sound processor, generates a second sound signal based on the first sound signal, and transmits the second sound signal to the second sound processor;
• the second sound processor performs signal processing to the second sound signal to generate a third sound signal;
• and
• the sound device receives the third sound signal from the second sound processor, checks a state of the second sound processor based on a signal received from the second sound processor, transmits a fourth sound signal based on the third sound signal to the first sound processor when determining that the state of the second sound processor is normal, and generates a fifth sound signal based on the first sound signal or the second sound signal to transmit the fifth sound signal to the first sound processor when determining that the state of the second sound processor is abnormal.
