音频播放速度与接收速度不匹配

官方的USB音频例程中,USB下传的速度与MCU传送给(wm8960)coder的速度不匹配,造成缓存在音频buff的数据越来越来多,最后USB下传的数据覆盖了即将播放的数据,造成声音波形断续。请问我该如何处理这个问题?

 

In the official USB Audio routine, the speed of USB down transmission does not match the speed of MCU to (wm8960) coder, resulting in more and more data cached in the audio buff. Finally, the data transmitted by USB covers the data to be played, resulting in intermittent sound waveform. How can I deal with this problem?
