But it only happens the first time I start Jack, after that it doesn't do it anymore _unless_ I change which device on the card is being used by JACK.
My guess is that devices on sound cards have a default sample rate, bit rate or some other type of setting and when something accesses the device and changes one of those settings, it results in that pop sound.
