PipeWire is aiming, and positioned to be this service. I don't have a particular case for low-latency audio so I can't comment on that but it is amazing that you can use pavucontrol to tweak your device configuration and volumes then use qjackctl to wire the devices however you want. I'm impressed at how well it works and it even supports better bluetooth codecs than pulseaudio does.
It has already shipped by default in Fedora and is available in Arch and NixOS. It does look like it will quickly wipe out PulseAudio by default. I'm sure Jack and ALSA will hang in there longer but they are already used much more rarely (by users, the ALSA API will stick around for decades more I'm sure).
