"Could not start MOD Host. Process crashed." error on JACK/PipeWire setting #41

Closed Inqb8tr-jp closed 10 months ago

Inqb8tr-jp commented 10 months ago

I downloaded ver 0.0.7 on my Manjaro Linux with MOTU M4 audio interface. Works fine when I select "M4, USB Audio (hw:4,0)" but the audio interface disappears on the qpwgraph. When I select "JACK/PipeWire," the error "Could not start MOD Host. Process crashed." window pops up. screenshot_2024-02-04T16:45:10

The following output appears on the console.

if you run the included jackd (same dir as the mod-desktop binary) with the CLI arguments as described in the logs, does that work?

Thank you for your reply. I got the following output.

right, it needs a little env var first, just this:

from the logs I see it never tries to connect with pipewire, and tries to use regular system jack2

you are using pipewire, correct? do you have the pipewire-jack stuff enabled? also, what is your pipewire version?

maybe try running as pw-jack ./jackd ...

even with that it cannot find the pipewire-jack libs, something is off.. I only tried this on a debian system and it was working there.

see if you find where the pipewire jack lib is located, and set an env var to it, like this:

the one with the "segmentation fault" looks good, it crashes just like on the GUI side startup. start it with gdb (as gdb -- jackd ...), then r to run and bt to get a trace of the crash.

I'm sorry I don't know well about gdb.

Don't know much about GDB too sorry =/

victorolinasc commented 10 months ago

I've just checked and pipewire has a bug release 1.0.3 (not yet on Fedora) that says

Fix ALSA version check. This should allow the alsa plugin to work again.

Although it has nothing to do with jack per se and every other software audio is working here besides the mod-desktop.

I can try to run things here although I am more of a memory-safe language programmer and haven't melded much with C/C++ and GCC/GDB

Thanks for your wonderful work @falkTX I'll keep testing the betas or anything here!

falkTX commented 10 months ago

The Fedora part is not the same issue, this log line is very clear:

Failed to load JACK DLL, reason:
/usr/lib/pipewire-0.3/jack/libjack.so.0: cannot open shared object file: No such file or directory

something is missing?

oh yeah the export was meant for archlinux, not fedora.

on fedora the pw libs are found properly, you dont need to set the path to them. anyhow, this is a completely different issue (just with similar results), please open a new ticket for it.

Here are my results when run in Arch. Maybe it will be somewhat helpful. Without running e. variables:

potentially fixed with the latest 0.0.8 release, please check, thanks!

Inqb8tr-jp commented 10 months ago

On Manjaro the ver 0.0.8 works fine. Thank you.

I experienced the same error with version 0.0.12 when starting it after Ardour has been started. However, now it seems to be no issue. I'm using jack2 started by qjackctl. The terminal output is:
