Zoals je ziet gaat niet alles een twee drie zoals het moet, ik denk dat je ook veel info op het net moet zoeken hoe het een en ander te tweaken.
Hierbij in ieder geval http://jackaudio.org/documentation
Ik hoop dat je wat aan bovenstaande hebt verder heb ik nog niet heel veel know how van jack en heb me zelf nog niet de tijd gegund om er wat dieper op in te gaan.
Met vriendelijke groet,
