在通话中打开扬声器，在Android 10及以上版本中不工作

权限

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.RECORD_AUDIO" /> (Optional)

当应用程序在前台、后台和从后台删除时尝试。在任何情况下都不起作用

我已经查看了谷歌开发者网站，但没有提到安卓10限制或其他不起作用的东西。如果有人有线索，请提供建议。

您找到解决此问题的方法了吗？我也有同样的行为。
