qjackctrl and cadence does not work (qjack shows jack as running but setting it up with a different buffer changes nothng)
that is expected when you run pipewire as a replacement for jack. buffers and stuff are set app per app. the drop-ins are there to be able to connect stuff. apps that don't have to option are set with
I suspected something like this.

Any idea why my I'm unable to set buffers lower than 256? Just a constant stream of xruns then.

I have no clue. tryed it one day and couldn't realy make it work. to make things worse, the alsa driver for my firewire device isn't realy usefull, so I gave up without trying too much

Hmmm. Think I'll wait... quite a while.
On a not particularly modern machine I'm running 48k at 32 frames *3 under jack without any Xruns

Whats your hardware / linux setup?

I struggle at 64 some times with too many plugins on a ryzen 3700x for some reason.

Dang that is much better than what I have got out of my computer so far, haha.

Could it be the rt kernel is that important? I have tested several distros so far, including ubuntu studio with low latency kernel, but never got below 64 without a lot of x-runs.

Maybe some USB settings? I dunno.

Guess I'll see when I try out the next AV Linux at some point ;)

Rosegarden has a small CPU footprint and can't load LV2 plugins, only LADSPA and DSSI. So most Rosegarden projects run fine even on older computers.

Pipewire certainly looks promising to me. Good to have some testers from the 'proaudio' community.

Watching the session on LAC I'm cautiously optimistic, although I'm concerned that it appears to be yet another lay on top of others.

My impression derives also from the LAC talk and the reactions by people who have the expertise to judge.

Pipewire is a layer above JACK, so JACK ain't dead. In fact, with a usb soundcard for JACK, I've no real problems with pulseaudio vs JACK. But it would be nice if the PipeWire API will fix some design mistakes of JACK (looping etc.) eventually and develops it strong points further.

So test, report and ask I would say.

Pipewire is not a layer above Jack, it's a layer above ALSA drivers and a drop-in-replacement for JACK.

As the person above me stated, it's not on top of jack. I ran it for some days for testing purposes and you need a pipewire-pulse and jack package to handle the API calls that pulse and jack applications make (think kinda like jack-pulse bridge, but it actually replaces pulse - and jack). Jack is still installed for most since it's a dependency for stuff like firefox. But neither jack nor pulse was running while I was using pipewire. On the arch testing repo I ran it had removed pulseaudio completely.


There are some bugs to iron out for sure, but it's a promising project.

OK, this wasn't clear from the presentation. The drawing they showed seemed to suggest it was an additional layer, rather than a replacement. I won't be looking at it myself for some time though. I've got far too much going on with Yoshimi!

you can run it as a replacment for jack (dropin installed), or you can run it seperatly. I haven't managed to expose pipewire to the jack server though

I've tried it a few times. I won't be trying it again soon. Just like PulseAudio, it can stay away from my system.
