AFAICS, even libjack only provides functions to start/stop the transport or get/set the current frame. Unfortunately, the Jack2 DBUS interface does not seem to export access to this functionality at all: https://github.com/jackaudio/jack2/blob/364159f8212393442670b9c3b68b75aa39d98975/dbus/controller_iface_transport.c You could write your own minimal JACK client to query the transport frame and check again a few milliseconds later to determine whether the transport is running. Using the jacklib.py module included in Cadence (and which I borrowed for jack-matchmaker[1]), this is very easy to do in Python: https://gist.github.com/SpotlightKid/420b975c296b08bfc5ecdcbe82cedba7 Chris [1] https://github.com/SpotlightKid/jack-matchmaker/blob/master/jackmatchmaker/jacklib.py
