Sorry for the confusion. > > David, did you had a chance to test the patch? Hey Sebastian, sorry for the long delay! I got busy with other packaging/ infrastructure things and nearly forgot about this one. I have now tested with 5.11.2-rt9 with and without your proposed patch. Without the patch [1], the behavior is as before, only the parent device node of the controller (/dev/fw0) is created, but the attached audio interface is not recognized. With the patch applied [2], things get a little more exciting, as now both the parent and the child node are created (so both /dev/fw0 and /dev/fw1 show up). However, starting jackd on the interface leads to a zombification of the jackd process and the process never exits: ``` Starting JACK server using fw-fireface800-48000.conf profile... no message buffer overruns no message buffer overruns no message buffer overruns jackdmp 1.9.17 Copyright 2001-2005 Paul Davis and others.
