this is my xinitrc
if which dbus-launch >/dev/null && test -z "$DBUS_SESSION_BUS_ADDRESS"; then
eval `dbus-launch --sh-syntax --exit-with-session`
fi
sxhkd &
exec bspwm
/usr/bin/pipewire

how do i set pipewire-pulse -a?
i typed pipewire pulse -a native but thats wrong

mplayer complain like this with pipewire installed
mplayer: error while loading shared libraries: libpulse.so.0: cannot open shared object file: No such file or directory
