问题定位
针对如下打印，猜测是音频流存入缓存时路径cache path有问题：

在源码中加上打印将缓存路径打印出来：
问题解决：OpenHarmony系统setting应用无法使用TonePlayer音频播放-鸿蒙开发者社区
打印结果：

而setting应用沙箱路径的物理路径如下，将红框中的phone改成entry，再次调用TonePlayer播放音频，功能正常使用！！

解决方案
由上验证可知，音频流的缓存路径默认是entry模块，而setting应用命名为phone模块，这里我直接将setting应用中的phone模块重命名为entry模块，重新安装后，TonePlayer播放音频，功能正常使用！！
