You can try to stop Jack and restart it for device 3 (notice: after a re-start of Linux the device number might have changed). Stop Jack:

Code:

pkill -9 jackdbuskillall jackd

Now start Jack again w/ the aforementioned command. I hope it'll work. If not then I hope that de developer of Ubuntu Studio is active on this forum and replies or maybe there's a separate forum for it. On the Ubuntu Studio website the "Features - Audio" page mentions Jack and not PipeWire. However this page of theirs does mention PipeWire. Ubuntu Studio recommends contacting the AskUbuntu forum for support: they apparently don't have a support forum themselves.

Apologies for the delay in answering:
There is a GUI in Ubuntu Studio from which you can configure everything related to JACK (Studio Controls), connected devices, the main device to boot with, etc. When I turn off the JACK service and try to boot it with priority to the ProFx10v3 device, even unplugging my Roland piano so it doesn't interfere, JACK simply is not able to boot. I can change the device settings (Sample Rate, Buffer Size,....), but in the end the message "Start failed" always appears.

If you have several USB audio devices connected, then you need something like this:

Code:

options snd_usb_audio vid=0x0a73 pid=0x0023 quirk_flags=0x20

Also note that latest LTS and stable kernels have a workaround for this firmware bug.

Well, this attempt has also caused the connection to my piano to stop working (only the sound comes out intermittently) , the version I use is: Ubuntu Studio 22.04.4 LTS, but taking advantage of the failure and tried installing Ubuntu Studio 23.10 (which uses PipeWire), I have also tried with Fedora Jam and AV Linux, (that's why I took a while to respond) the results are always the same, the Roland piano works perfectly as soon as I plug it in, the Mackie ProFx10v3 never works.
I'm starting to think that maybe there is some conflict with the system's audio card.. ???. I'll start looking for help in other places AskUbuntu... and if I don't find a solution I still have time to return the device, I was hesitating between this device and the Behringer XENYX QX1204USB which has similar features, does anyone know if this will work well with Linux?
Thank you very much for your interest. I keep trying and if I find a solution I will tell it here.
