Hello, I've successfully compiled and installed obs-studio with jack support. When I start it, it shows it's loading jack. That said, I am using jack2 and I don't see jack in the audio drivers available on obs-studio's settings. Any idea of what could be the problem? # OBS sample run renich@introdesk ~ $ obs --verbose Attempted path: share/obs/obs-studio/locale/en-US.ini Attempted path:

I've not played with JACK in a long time, but I have had other reasons to look into it for quite a while, and that inspired me to do so now. With regards to OBS Studio, I was able to get a 'JACK Input Client' by adding it as a new Source (not as a new 'Audio Capture Device'). Is this not what you're looking for, and/or is it not available in the 'Add' context menu for you?
Ah, you're completely right. Sorry for this; but thanks a lot for helping out. Not a bug.
Closing then. :] And no sorries; I'm glad it was easy to 'fix'.
