I think you will find this is because the PA-jack bridge is not
"finished"... actually it is example code which could use some love.
ignore the warning in other words. The reality is that Pulse does not
ensure bit perfect throughput anyway. Samples are lost over time whic is
why Pulse is not suitable for most proaudio applications with the
exception of live on air phone calls via skype.

Cadence is an all in solution. If it does what you need it is great, but
if you need something else, you need to learn what Cadence has done. In
other words you not only have to know jack and pulse, but cadence as well.

use Catia or the Carla. (my opinion)

Calf looks nice but there are others with better DSP.
