(I haven't used Ardour on that box of mine as it's too slow for that sort of thing.) That wasn't my point at all. Under Gentoo I haven't built in capabilities as I'm waiting for the new HDSP 9652 driver to get into CVS. Then I'll be able to rebuild Alsa without bothering Thomas. However, I'd agree with what I think your point is if I wanted real-time scheduling, but I didn't. I started Jack running normal scheduling as a normal user. All my other Jack applications have no problems connecting to the Jack server. Ardour said it couldn't connect to Jack. It was the only app that did this so far. Maybe Ardour cannot connect without real-time scheduling enabled? This didn't used to be the case, but possibly it is today? I don't know. Please understand I'm not asking you or Paul to change or fix anything. I don't care which way Ardour works. It's completely immaterial to me. My point was that if this father is going to turn his kid loose on his system learning Linux and Ardour, apparently on some distributions you have to be root to even start Ardour and that raises other risks that he might not want to take. (rm / ?) I know you don't do things like that, but my 11 year old kid does, so I'd never let him touch Ardour running as root on one of my systems. Longer term maybe more distributions with have the capabilities thing enabled out of the box, but I've been told there are good reasons not to do that so I wouldn't guess when it will happen. Mark
