Hi,
Next PipeWire version will have a rewritten jack backend (make
PipeWire become a JACK client based on jackdbus) that will also dlopen
the native libjack.so to make it easier to mix jack and pipewire-jack.
There has also been work on implementing multithreading in the
pipewire server which will make it possible to use a dedicated thread
for a device (used for the new JACK backend to use the native jack
thread to run the pipewire graph). This should then also make it
possible to use ffado as a device.
I'm still experimenting with some options for this but FFADO does not
seem as out of the question as it seemed some months ago...

The last I heard, there are no plans to implement any Jackd backends in
PipeWire. That includes net, FFado etc. There is already an auto dummy
device in Pipewire, but I do not think it is as flexable as the jackd
dummy backend.
In theory, Pipewire should be able to use a running Jackd as a device.
There are some problems with this. Libjack must be one of jackd1, jackd2
or pipewire. If Pipewire is set up to act as jack, then starting
jackd(bus) will not work as planed because jackd will try to load
pipewire's libjack and fail. So jackd must be run from a script that first
resets the environment libpath to point at jackd's libjack before running.
I have not heard anyone who has said they have done this.

To unsubscribe send an email to linux-audio-user-leave(a)lists.linuxaudio.org Pipewire has gotten around it because they
don't use device interupts. They
can give jack clients whatever buffer size they like so long as the entire
buffer is big enough. That is probably not an entirely correct assesment.
All I know is that jack with ffado is rock solid.
What do you think: Will pipewire finally support ffado?
