Hi
I’m having problems getting ardour (or any jack software for that matter) to output to the audio interface. I’m running manjaro linux with kernel 52, on a macbook pro 13" from early 2015. The connections for “system” appear in the Qjackctl graph as shown, but there is no sound output no matter how i connect them.
My log looks like this, there’s no error that seems out of place to me?

I’ve tried using the intel PCH, as well as the Cirrus C4208 DAC, but both have the same issue, and I’ve also disabled pulseaudio on startup.Is there a config file to configure jack system outputs or something? Some guidance would be appreciated.
