Issues starting Sonic-PI

General system Applications
1

I’d really like to try using sonic-pi to play around with but am struggling to get things working. My system is setup using pipewire but admittedly my undetstadning of these lower level multimedia frameworks is limited.

I tried booting it using pw-jack sonic-pi as I understood that this provides a way to handle jack clients which I assumed this application expects?

In the logs I can see it complaining about jack_connect being missing :confused:

Here is the log output:

There’s a new package of pipewire-jack just hitting [testing] that might also fix this.

Thanks for the reply - what makes you say that it might fix it?

I’m guessing this is something that’ll just need to wait to see when it hits extra right? Or can I easily pull in just this one dependency change?
