PipeWire compatibility

[mxmilkiib]

PipeWire implements the JACK API to allow interoperability between JACK, ALSA and Pulseaudio.

I don't think seq66 plays well with it atm. I see [seq66] JACK server not running then when I select to use JACK then close and restart, the main seq66 window does't show up.

Also I see errors at that point;

Pipewire is supposed to have a JACK compatible API so that existing applications that work with it. But these links indicate there is some setup to do, depending on the system. https://wiki.archlinux.org/title/PipeWire#JACK_clients That indicates running the audio app in what is essentially a container. https://askubuntu.com/questions/1339765/replacing-pulseaudio-with-pipewire-in-ubuntu-20-04 The only pipewire packages on my Ubuntu 20 laptop look to be pretty old. That link documents the use of a PPA to get the latest pipewire infrastructure. I will eventually look more into this issue (including if there are easy additions to seq66 itself), but I don't want to mess with that PPA right now, since I jacked up (get it? get it?) my system the last time and felt compelled to reinstall. Stay tuned. If you learn anything more about working with pipewire, let me know! Thanks!

I'm using the pipewire-jack-dropin AUR package to avoid having to prefix commands. It's surprising how easy it was to get PW working. Maybe if you have a spare laptop it could be worth throwing Manjaro on it, or it's really easy to make a persistent Manjaro USB stick (from a Manjaro environment, which one can get to just using a standard liveusb .iso stick).

Can there eventually be a section in the README, or wherever documentation is being collected, on pipewire compatibliity etc.. ?

There's mention of it in the "Let's Go!" chapter of the user manual. I could add it to the README and the INSTALL. But need a little more info. I see in the Arch AUR package in distros/arch that there's a "pipewire-jack-dropin" package. But I haven't tried pipewire or the drop-in yet. If you have pointers concerning the Pipewire drop-in that would be cool. I've gotPipewire support on tap for version 2 of Seq66, but that is wayyyyy down the road.
