Have you been using some GUI to be able to control volume, etc? I've been holding out on replacing PA with PW on Tumbleweed until [1] is resolved so I can continue using pavucontrol (pavucontrol's deps will be satisfied by pipewire-pulseaudio and not only pulseaudio), which is currently blocked at [2] being accepted. Probably another week or so.
