Unable to hear caller or speak after answering a call

Yes, it's best to do this with Manjaro's/Arch's command line package manager pacman.

Code:

# install the pulseaudio packages
sudo pacman -Sy pulseaudio pulseaudio-alsa pulseaudio-bluetooth

# remove the pipewire packages
sudo pacman -Rs pipewire-alsa pipewire-pulse

# find out about pacman's capabilities and see what the flags do
man pacman

When you install the pulseaudio packages you might be warned about conflicting pipewire packages and be prompted to remove them. Do that, you won't have to remove those in the second step then. You probably won't be able to remove the pipewire packages with their dependencies first though (before installing the pulseaudio packages) because other packages rely on them.

Thank you kqlnut, that did resolve my PinePhone Pro issue with the Plasma Manjaro dev OS.

I wasn't able to hear any sound from phone calls; yet I can hear my voice only; nor the caller was able to hear me from PPP.

Thank you!
