Brett, I'm not running Ardour these days, but I have used it a lot. Most of this is from memory.

Will it service any users who need it then? Jack can run as either root or brett. All Jack applications must run as the same user, either root or brett. Jack will not service all users. A couple of things about Jack. It now uses tmpfs, so you need that loaded in fstab I think. On my Gentoo box it seems to be there, but mounted at /dev/shm. I don't know what Jack thinks of that, but it works for me. On my PlanetCCRMA system it's mounted at /var/lib/jack/tmp, which I'm sure is what the developers intended. Maybe you can make more sense out of this than me! A second thing about Jack is that it will only run with real-time scheduling (not really required, but advantageous) if you run as root, not as brett. This should not be required for testing. You'll just get more xruns if you don't use it. > > 2. Why is ardour not seeing jack when it's running - my understanding is > that Jack runs as root and then ardour will make a connection to it.

Depends on which version you are running. There was a release early this week that locked up, but then that was supposedly fixed. Are you using an ebuild or building from CVS? - Mark -- [EMAIL PROTECTED] mailing list
