I have to use cachyos since I found a way to get my rme raydat interface working with bitwig. The only issue i have now is ardour (9.2-3.1) crashes on startup. Safe mode loads up but I don’t have my u-he plugins there. I’ve tried removing the .vst3 folder but still crash on startup after the memlock message.
It’s probably simple but I don’t know where to look for issues and I’m so tired of trying to work around issues that hopefully some generous folk might point me on how to get around this last hurdle to my fully working, “goodbye forever, Windows” audio machine!

I am asking because there is a bug in XWayland that allows you to interact with Ardour’s main window before setup is complete, which can lead to a FPE (divide by zero, because sample-rate is not yet set).
I think you can avoid this by first interacting with any Ardour dialog windows before moving the mouse to the main window. With X11 on cannot interact with the main window when there are modal dialogs.
yes.
after more fiddling:
I start the program for the first time and all is well until i close it and reopen - I get the SIGFPE error in the konsole.
cleaning the apps config gets the app running again. Something seems to be getting stuck. probably my rme raydat’s i/o streams? IIRC i get two audio streams for i/o rather than a single one for the interface. I think one of the streams is left open so ardour can’t use it on next launch…??
I’ve had so much struggle with this raydat in linux. I have a feeling herein lies the problem
Another option is to uncheck “Auto-start the audio setup” so that that dialog always pops up. That might be why I’ve never run into this bug (the main interface I use with Ardour isn’t usually plugged in and sometimes I just want to use my desktop’s audio interface for some quick mixing, so I don’t auto-start the audio setup and configure it every time).
