Manjaro ARM 20.04

From your post, it is clearly at least partly a software issue
Dying  hardware can sometimes exhibit these sort of issues too,
but if sway always works, this is not likely
xfce, try armbian, that is their default wm OR the original mrfixit
OR fedora,,,,  https://builds.armdevelopers.com/pineboo...eases/dev/

Yes, I bought Pinebook pro about two months ago; I will be very surprised if it is a hardware problem.

I tried both Armbian and Fedora XFCE. Both are very nice; I particularly liked Armbian and Fedora XFCE feels very modern. However, both of them have soundcard related problems I belieive. When I use my wired headphones, I end up having sound from both speakers and my headphones. I switch to headphone from from the pavucontrol and the problem disappears. However, having to manually switch the sound interface concerns me.

Armbian has an additional sound related problem in that volume up and down keys do not work. I removed the pulseaudio aplet, the alsamixer shortcuts in the default keymappings and installed xfce4-volumed. After adding the volume applet to panel the volume keys somehow worked but I receive multi notifications when I up/down volume. I am guessing the default volume applet is still somewhat working in the background.

Due to the sound issues I will switch back to Manjaro XFCE. None of the above problems exist in Manjaro; yet it has its own issues related to wifi/bluetooth.

I am particularly interested in Armbian. If I could fix the issues, I would definitely use it as my main system. For the records I tried Armbian Focal with 5.8 kernel. Any help would be appreciated.
