Stephane is right, qjackctl makes no use of the d-bus interface in jackaudio.org domain, although the latest in qjackctl cvs has some d-bus stuff of its own (rncbc.org domain) and only serves for starting/stopping qjackctl control--found useful for example to any system suspend/resume script you may think of. otoh, the only other jack application i know of that writes to ~/.jackdrc is ardour; have a look at your use case when starting jackd from behind ardour's open session dialog... cheera -- rncbc aka Rui Nuno Capela rncbc@xxxxxxxxx _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
