I've been using jack and qjackctl with audacity under Linux (FC6). It seems to be working OK with 1 approx 1 msec xrun in a half hour recording session, when unfortunately my backup system kicked in.
However there's something I don't understand about jack, even after reading a lot of the documentation. At the bottom of the qjackctl window is a set of arrows, like on an audio control device. When I click on the arrow pointing right, the green "Stopped" in the main window changes to "Rolling". What does this mean? What are the other arrows for? No useful info on the web. The above recording session was done while jack was "Stopped". Would jack work better if it were "Rolling"? Please excuse these elementary questions. Thanks - jon
