Pa_OpenStream error = Unanticipated Host Error

[ghost]

I've been having this issue lately when trying to start Jack - Port Audio via QJackCtl. Jack cannot start no matter what I try. Jack will boot properly via dummy, although the result is that QJackCtl lags alot. Also, I've tried editing settings in the GUI for my Focusrite 2i2 (the interface i'm trying to use with Jack), and Jack will boot properly when I enable "playback only" mode instead of duplex. Here's my logfile for some context.

Any ideas?

sample rate is set to 22050, that might be why. this is super odd though...

-p1024 -u -dportaudio -r22050 -p16

did you manually added -p1024 in there??

No I didn't. Also I've been upgraded to QJackCtl refusing to open at all, even after reinstalling it. So now I cant even go in and mess w/ the sample rate.

This program will reset qjackctl settings. Maybe qjackctl will run after running it: https://github.com/kmatheussen/reset_qjackctl/tree/main/bin_windows

You can also try this version of qjackctl: http://users.notam02.no/~kjetism/qjackctl.exe This is the one that's included with radium.
