If I type on a command line (omitting the -d):<br><br>jackd -R -dfirewire hw:0 -r48000 -p1024 -n3<br><br>then jackd starts normally. If I then tell Qjack to start jackd, it finds jackd already running and controls it just fine from then on. I can start japa and ardour and patch them to my Edirol FA-101 in the Qjack connect window (it all works great!). Qjack will also stop jackd correctly.<br><br>Have I got the wrong version of something? Did jackd forget his interface options?<br><br><br></div></body></html>
