I'm curious what you think of PipeWire:

https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Per...

It claims to get near Jack latency, while implementing a more generic audio graph with better security than PulseAudio.

In regards to Linux scheduler performance, do you have any experience with SCHED_DEADLINE?

We don't use SCHED_DEADLINE with audio, because things are driven by hardware interrupts/requirements, which makes SCHED_FIFO more appropriate ("wakeup! time do the work! right now! until it's done!"). macOS doesn't really have SCHED_FIFO, so we end up forced to use something to deadline scheduling there. It works fine.

I commented a lot on PipeWire when it started. Thankfully Robin Gareus and others managed to get its developer to change course somewhere along the journey to use a better basic model (notably, pull not push). I no longer follow its development. If it works, it will be good for Linux audio. I don't know if it will, or won't.

[for anyone who doesn't know, I'm the original author of JACK]

Hey, thanks for all your work.
