Try various Audio Sources.
Call recording is quite a mess on Android. Might not work on various devices, and work on others.
And each has its own configuration to try.
I wonder though what else can be configured, because I've noticed other apps can handle cases that changing the AudioSource alone can't handle, so I've written about this here:
