I think I must have done my head in with all that googling. Another look at the man page for chrt, and the process was so simple. One xrun after 6m 33secs of 0.253 msecs, which is what I'm getting on Fedora 7. Will that change of priority I've made for the soundcard on the current pid, hold after a reboot?
