小米 MIX2，LineageOS16，也出现同样问题，权限里倒是有录音权限，也给了，但没用，现在能发语音，不能微信电话，不知道是不是 los 的 bug，凑巧赶上 los 因为 license 问题暂时停更了小米的设备，这个问题困扰一个多月了_(:з」∠)_

看起来的确是 Los 的问题，XDA 论坛上有很多人问了~看起来要么换别的系统，要么等更新。
> After upgrading LineageOS 16 to recent one and firmware to 10.4.1.0 I can't hear anyone and they don't hear me in the apps like Skype and Telegram. But phone app works well and microphone can record audio. Does anyone has the same issue?
> I'm also having problems with VoIP Assisi calls using WhatsApp and Zoiper. Didn't try skype but I suspect it will also be problematic.
> I have the same issue with Facebook Messenger, not tried other services. Also running latest LoS and firmware.
