Is it the same for you ?
im using an os based on arch.
If you want to replicate the bug, make a call and in alsamixer mute earphone, unmute speaker, enable mic1 boost, and see if the other side hear noise.
Thanks.
Most likely, it audio coupling of the speaker to the microphone, with a lesser chance of being electrical coupling. Note that with the speaker muted, there could still be some noise (see https://forum.pine64.org/showthread.php?tid=13922) but with the speaker unmuted, the speaker is most likely the primary cause.
