Question, did the patch have "rt_prio" or "rtprio" in it? Not sure if you saw my other email about it, but the official PAM has "rtprio" and most patches I saw out there had "rt_prio" in one place, but "rtprio" in another (in the README). By default, you are in the audio group, so I would propose a realtime group. It makes sense anyhow, since that's what it is for. Also, the recommendations I saw elsewhere said rtprio = 99 (some say 100, but looking at the patch, 99 is the max), nice -10, and memlock I am not sure about. I set mine to 250000, but others put 4000000 even. On another note.. I hope that the new Ardour 0.99.1 gets into Dapper too. It has a lot of maintenance fixes. Dana
