<div dir="ltr">Hi Andrew Thanks for responding to my queries.  I've now added raw1394 to /etc/modules, as you said, and that bit works fine.  You mention that "having -controls add raw1394 to /etc/modules" is not a bad idea.  I'm not sure what that means, though.  Are you saying I should type it like this - "raw1394 -control" (without the quotes)? The command I use to start jack from the terminal is just the one I copied from your former post (I'm afraid I don't know that many commands!) - "jackd -d firewire".  I still get the same error message (as when I had to modprobe) in the terminal, as follows: JACK compiled with System V SHM support. loading driver .. firewire ERR: Incompatible libffado version! (libffado 1.999.36-) cannot load driver module firewire no message buffer overruns no message buffer overruns And ffado still (probably obviously) doesn't appear in qjackctl. My system is completely up-to-date, including the last jackd update. Thanks for your help. Neil PS - I'm not sure of the correct way to reply to the Digest, I hope I got it right this time, but I'm sorry if I messed up again. </div>
