参考实现源码：

demo中的主要修改点如下：

  1. 修改蓝牙同步时钟为本地时钟 imageimageimage
  2. 修改dac输出为主设备输出 image
  3. 使用switch 节点将媒体音频流数据同时输出给到PC_MIC 上传 数据流参考如下：
    imageimage 代码修改switch 的获取状态判断代码

修改USB 插入上线时候，直接启动pc 功能，不需要切换模式
image 处理第一次拔出USB后无法挂载问题
image 处理 在 OTG 上传时直接拔掉USB接口，导致媒体或mic_effect 等switch 上传OTG的数据流dac 无声问题，log 异常一直打印fffffffff
