If you try that it will help to rule out to be an issue of any jack client.
you can try to run jack with --verbose, maybe it gives another hint.
I did that already, see the pastbin links below:

SR.
jack_bufsize buffer size = 1024 sample rate = 48000
the alsa
device could be the issue. you could try to start a dummy jack
and add the alsa device with alsa_in to see if it makes a difference.
also make sure that you use a vanilla jack (git clone
https://github.com/jackaudio/jack2/) to rule out any other side-effect.
OK, I will compile from source later an re-run the captures.
Thanks again
