我正在将AOSP(Android 10(移植到一个新设备上。音频正在工作。呼叫音频不工作。

我在这里看不到任何错误。
我也看不到任何迹象表明新路线正在使用。(通话中还没有音频。(
我如何让Android注意到audio_policy_configuration.xml的添加，并让它在通话中使用路由的Telephony Tx和voice_rx？
当查看这个也有Telephony Tx和Telephony Rx端口的示例时，与您的配置相比的一个区别是，它还定义了从Telephony Rx到大多数接收器以及从所有麦克风到Telephony Tx:的路由
<route type="mix" sink="Speaker"
sources="primary output,deep_buffer,compressed_offload,BT SCO Headset Mic,Telephony Rx"/>
<route type="mix" sink="Wired Headset"
sources="primary output,deep_buffer,compressed_offload,BT SCO Headset Mic,Telephony Rx"/>
<route type="mix" sink="Wired Headphones"
sources="primary output,deep_buffer,compressed_offload,BT SCO Headset Mic,Telephony Rx"/>
<route type="mix" sink="Telephony Tx"
sources="Built-In Mic,Built-In Back Mic,Wired Headset Mic,BT SCO Headset Mic"/>
这可能是您的配置中缺少的部分内容，以便路由正常工作。
由于某些原因，Telephony Rx没有被添加为Earpiece信宿的源。我不知道为什么。也许是疏忽(？(。
如果您使用的是Agora Android视频SDK，那么您可以使用setDefaultAudioRoutetoSpeakerphone方法
