Android7.1 应用默认播放设备

qw1031150349

Android7.1 功放默认选择了rkhdmidpsound作为播放设备。
我使用的是第三方的功放，tinyplay播放正常，在安卓端点击APP默认声音输出是rkhdmidpsound，请问如何修改为自定义的功放设备？

意思默认要从aw8226输出，不要从HDMI输出吗？

对的，是这个意思

qq号2317783075

Android默认是接了HDMI 显示器后本体Audio就不出声了，可以自己进行修改播放路由选择

老哥有修改思路吗，是修改HAL层还是framwork层，不太熟悉Android，可否提供些思路呢

替换附件库试下

现在Android7可以播放了，还请帮忙导出一份Android10的对应文件

附上Android10 的logcat日志
