Hi Mike,

Have you tried changing some of the settings in Jack to get rid of the
xruns? I started qjackctl, clicked on setup and on the settings tab I
changed the "periods/buffer" from 2 to 4. This increased the latency
(it's tolerable) and stopped the xruns.

I hope this helps. It's a fantastic system when everything is working
