The jack developers have always been very insistent that two versions of jack can never be installed simultaneously. Note that having jackd and jackdbus installed does not necessarily imply two version of jack, because the jack2 installation will create both jackd and jackdbus binaries if dbus support is configured during compilation. One thing to try may be checking the dbus enabled selection in the qjackctl advanced setup tab, that way the same executable is started by qjackctl and by renoise, so if jackdbus is already running when qjackctl starts it should be able to display the current status, and not try to start a new instance. I run fedora, so there is only one jack package available in the official repositories (jack2, with an optional dbus support package which can be installed). If your debian repositories contain packages for both jack and jack2, only one should be installed, not both. If there is a possibility that the jack binary is from jack (ver 1), if you decide to keep the jack2 package you should probably re-install to be sure that any shared libraries which have the same name in both packages come from the correct package (jackd, libjack.so, etc.). -- Chris Caudle _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
