Sorry for the late reply. I did “Install Boot Override” but the sound mixer software would only show a single port. After months of disgruntedly using Windows I finally “fixed” the issue by installing manjaro-pipewire and inputting these commands found on reddit:
systemctl --user mask pulseaudio.socket --now
systemctl --user disable pulseaudio.service --now
systemctl --user enable pipewire.socket --now
systemctl --user start pipewire.service
Second command failed but after a reboot I finally can switch between headphones and speakers. Unfortunately pavucontrol will still only let me switch between specific devices for programs, not ports… (Browser with Youtube to speakers, Teamspeak to headphones is the desired usecase).
I’m honestly shocked that basic audio for common hardware is still this troublesome in 2021. Thanks for the reply nikgnomic but that’s way over my head.
