I’ve been noticing the same thing on Windows lately as well (using head of v2 branch as I type this), hangning in RtAudio on startup once every 3 or 4 launches of Rack. I don’t think this was happening with the early v2’s, so perhaps something has changed in that library.
@marc_boule - could this possibly be related to that bug I am getting where a patch loads from template in the VST and the Audio Module is actually at 44.1 kHz sample rate even though it says it’s at 48 kHz (fixed by initialising the audio module).
I’m also getting an issue where when I save a template in Live that has VCV in it, although working fine when I save it, when I try and open that template again Live is crashing (and the template/project is therefore essentially lost… again, could possibly be related if it’s Rack crashing when opening and taking Live with it. Need to investigate this one a bit more though.
I don’t know, but for any crashes I’ve been having with Rack2 CE, I’ve been thinking that it’s cause by ABI incompatibilies with plugins vs Rack, and so I’ve recompiled everything from scratch and it seems to work.
For Rack2 SE, I couldn’t get the version I downloaded with our dev access to start up (it was always crashing), but I tried the idea of replacing the Fundamental plugin by one I built myself against the latest Rack CE (219bbaf1), and Rack2 SE is working fine now.
Since I didn’t see anyone mentioning this, and devs seem to have their Rack2 SE working, I thought it was just me, but come to think about it again, I think perhaps the Fundamental pack that came with Rack2 SE might not have been the correct version. I’m not sure about this, and not pointing out a fault, but those were my experience and thoughts. EDIT: after trying it again on another PC, it worked fine, so it’s probably not the case.
