Inverted speaker stereo polarity

Hi,
I've been using my Pinebook Pro since January and one of the first things I notices about the speakers is that one of the speakers is in reverse polarity from the other.
This results in audio that sounds very weird with almost a kind of a fake "surround" effect.
Here is one video that you can play to verify this situation yourself.

This only appears on the speakers, not the headphones. I also tried to look if it is easy to reverse the cables but it's unfortunately not and the cables are very thin and I'm not confident enough of my soldering to hack it in hardware.
One way to fix it in software is to use alsamixer and then enable either "R invert" or "L invert", however, now the headphones have incorrect audio.
I'm curious if your Pinebook Pro has similar issues and how did you solve them. I will probably try to hack it on the hardware level at some time in the future.
