Hi Christoph, Some extra info: In case your system does allow real-time, it could be that the maximum priority is set too low. Zita-ajbridge will run the thread talking to the ALSA device with a priority that is 10 higher than Jack's callback threads. So if your jack is configured for e.g. 80, and the system limit is 85, zita-ajbridge will fail.
