No sound in calls on Xiaomi Mi A1
Summary
There is no sound (incoming/outgoing) during voice calls, regardless of who initiated the call. If I use Signal for voice calls I can here the other side, but they can't here mere. I can record from Mic and send/receive/hear voice records from Signal.
Steps to reproduce
Fresh install or upgrade.
Fixes
adb root
adb remount
adb shell
nano /system/build.prop
set "persist.vendor.audio.fluence.voicecall=false"

It will be nice if I can toggle this setting from Settings (eg. through the developer menu), because I have to do the adb dance again after /e/ upgrade. Also, the lowest volume is still too high (people around me can easily hear what the other side speak), but I don't know how it was with stock android.
