I find: pasuspender --sleep 5 & ; jack_control start Will allow me to start jackdbus even while pulse is streaming. Actually I use pasuspender from qjackctl to do the same thing. > I have noticed some issues with jackdbus though: > > a] jack_control start sometimes doesn't work at all after the first time > it failed to aquire the device.

This is part of the bug above, when jackdbus fails to get the device, the jackd part dies but the dbus part doesn't (it seems, I don't know the code well enough) It would be interesting to compare this behaviour with jackd2. > b] after some hours of operation jackdbus starts to eat 100% cpu on two > of my four cores. I have left jackdbus running for at least 5 days and have not seen this show up. PA has been used during that time (audacious and fire fox) as well as other jack clients. I would be interested to know if running jackd instead of jackdbus is the same or different. There are some patches on the way for jack2 in ubuntu as well. (in testing) > > Are these known issues?
