Well-integrated desktop environments should have this built in (GNOME
certainly does).

If you're building your own desktop environment from smaller pieces,
then you've taken some of the responsibility for doing the necessary system
integration and finding a combination of components that works together.
Not all of them are necessarily going to come from the same upstream.

It's fine to control Pipewire via PulseAudio's IPC protocol (that's what
gnome-control-center and gnome-shell do!) and if that doesn't work,
then it means pipewire-pulse is not fully doing its job. Switching to
a different sound server implementation shouldn't require rewriting
every graphical and TUI/CLI mixer/control utility, if the compatibility
layer is good enough.

If you prefer to use CLIs, pw-cli is a low-level CLI for Pipewire, and
wpctl is a somewhat higher-level CLI for Wireplumber; they're analogous
to PulseAudio's pacmd and pactl.
