Andrew, I am doing this from memory but try the following as an alternative to your jack line in rdadmin:
jackd -R -d dummy -r 48000 then ps ax | grep jackd should show something like: $ ps ax | grep jackd 4243 pts/4 SLl+ 0:00 jackd -R -d dummy -r 48000 4262 pts/19 S+ 0:00 grep --color=auto jackd but not quite as I started that jack from my user terminal but Rivendell will start jack as root on startup.

To get your desired card back for jack use, you most likely have to run rdalsaconfig (or has it changed? memory does not serve, my 3.x test/learning box is not booted up right now) and deselect it. Switch back from my dummy line to your alsa line and try again. > If I try and manually start jackd using QjackCtl I get the error message > saying that hw0 is already in use and cannot start.

(If you are on a centos7 install that is, which all of this is assuming) Pretty much everything jack *and* rivendell related must be run as root so they can see and interact with each other. > Can anyone point me to somewhere that has a good guide to get jack running > on centos7 & Rivendell 3.4? > Nope, but if you come to #rivendell on freenode irc, you may find someone willing to walk you through a setup interactively. > > TIA > Andrew > > all the best, drew -- Enjoy the *Paradise Island Cam* playing *Bahamian Or Nuttin* - https://www.paradiseislandcam.com/
