[...] client event poll on 13 for qjackctl starts at 19123690163 back from client event poll after 13 usecs start poll on 7 fd's could not handle external client request server thread back from poll marking client rosegarden with SOCKET error state = Not triggered errors = 0 waking server thread trying to lock graph to remove 1 problems we have problem clients (problems = 1 ++ Removing failed clients ... client oss error status 0 client rosegarden error status 10000000 removing failed client rosegarden state = Not triggered errors = 10000000 removing client "rosegarden" removing client "rosegarden" from the processing chain +++ deactivate rosegarden [...] and rosegarden says...

(..and without jack support enabled in rosegarden I also didn't get sound even with the builtin synth plugin.) I'll Cc the rosegarden port maintainer. :(, Juergen
