Not quite yet. You _need_ pulseaudio installed, because it defines the API and ABI presently. I'm not aware of any way to build pulse software with i.e. pipewire as the bdep? > IIUC, pipewire was (at least initially) developed as > the "successor" of pulseaudio and not intended to be installed > alongside (choose one basis), and provides pulseaudio > compatibility for apps not yet natively support pipewire. pipewire-pulse (included in our default install) is a stand in. "Eventually," software should write directly to the pipewire graph. But that will take a long time, if ever, because Pulse wasn't awful as a client API (which is an easy problem space). Overall, pipewire is pretty nice. It is analagous to something like Apple's coreaudio. It can do bitperfect with my sink, and you can build graphs that avoid any SRC (Sample Rate Conversions) for proaudio and such. I've basically reached a local maxima on the sink to where the kernel would need some work to support things like digital passthrough or more pro audio oriented stuff, but I think it's basiaclly feature complete for desktop audio. > And when I've tried pipewire a bit in early days it appeared > in ports tree, I've experienced the same on Mate DE. > The only workaround was to deinstall pulseaudio, but as > pulseaudio is depended upon by many ports, upgrading ports > forcibly pull pulseaudio in again unless nothing depending > upon pulseaudio is upgraded. Read my instructions again and let me know how it goes. All you need to do is prevent pulseaudio from starting.
