I gave you the literal instructions higher up to get rid of PulseAudio and install PipeWire. 
sudo pacman -Ru --nodeps pulseaudio pulseaudio-equalizer pulseaudio-jack pulseaudio-lirc pulseaudio-rtp pulseaudio-zeroconf pulseaudio-bluetooth pulseaudio-pa pulseaudio-alsa pulseaudio-ctl manjaro-pulse && sudo pacman -S manjaro-pipewire
