The method includes: reading an audio file transmitted by the IS audio bus, by a master controller; the master controller reading sampling rate, data bit length, and number of channels of the audio file, and, calculating data volume for each frame according to the data bit length and the number of channels, generating a master clock signal according to a multiplier requirement of a slave controller on the master clock signal, a frequency of the master clock signal being f×X, wherein fis the sampling rate, and X is a selected multiplier; and the slave controller receiving the master clock signal, and using the master clock signal as a clock source, to realize modulation and filtering for an audio digital-to-analog conversion.",
