Sound Server "hanging" after upgrade

You have both pipewire and pulseaudio active, so you should remove one. The usual recommendation is to keep pipewire. You should install the full manjaro-pipewire metapackage, as that will automatically remove pulseaudio and replace old pulseaudio packages with their pipewire equivalents:

sudo pacman -Syu manjaro-pipewire
